Sea Jellies

Purple-striped Jelly

Jellyfish, or sea jellies, can be found in waters all around the world, but they are primarily translucent and difficult to see. For a good look at them, a visit to the Monterey Bay Aquarium is rewarding.

 

Highly regarded around the world, the Monterey Bay Aquarium houses 35,000 animals of over 550 species. The Aquarium is also prominent in research and commitment toward ocean protection and public awareness.

They have many exhibits with sea creatures, and about a dozen tanks filled with different kinds of sea jellies. (The term “jellyfish” has officially been replaced by “sea jellies” because jellies do not have spines and are therefore not fish. I use the terms interchangeably here.)

 

Sea jellies are gelatinous invertebrates and 95% water, and appear almost invisible in the underwater world. To aid with viewing, the aquarium tank backgrounds are blue and illuminated by side lights.

 

You can see in this photo what a sea jelly (center) in the San Francisco Bay really looks like — ghostly and almost imperceptible.

Sea jellies require currents for locomotion. In public aquariums,  there is a complex system for water flow, with precise inflow and outflow.

 

Sea Gooseberry Jelly

 

According to World Atlas, there are more than 2,000 species of jellyfish in the world, and it is thought that there are over 300,000 species yet to be discovered.

 

The sea nettles and purple-striped jellies photographed here are found along California’s Pacific coast. They are highly efficient in their movement, using muscles in their umbrella-shaped bell to propel; this is also where the mouth and digestive system exist.

Tentacles are the long stringy body parts, and have stinging cells, or nematocysts, that sting their prey. The “arms” are frilly extensions, and move the prey to the mouth.

It is a marvelous experience to observe this exhibit…mesmerizing. A dark room with colorful, glowing cases filled with exotic sea jellies. Soft music accompanies as we watch the jellies rhythmically pulse and propel throughout the illuminated tanks.

But . . . if you have ever been stung by a jellyfish, and I have, you don’t forget the sting, no matter how attractive and enticing the jellies appear.

 

The first time, Athena and I were snorkeling in the Great Barrier Reef when we came upon eight or ten sea turtles in one small area. Usually you see one or two turtles, but here we were thrilled to find so many.

 

When we swam respectfully near, we found ourselves in massive clouds of sea jellies. Each jellyfish was the size of a large coin, and there were thousands. The turtles, we realized too late, were there to eat the jellyfish.

 

Stung instantly and by the dozens, we shot out of that cloud like rockets. Came to the surface, stunned. Even so, we both laughed then and there, because the experience was so atrociously the opposite of what we had expected.

 

Within 24 hours the bites had disappeared; and thereafter underwater garments were purchased.

 

Most jellyfish stings are not deadly, but a few species can produce stings fatal to humans.

 

Usually I prefer seeing creatures in the wild, over observing them in an exhibit. But in the case of sea jellies, I think these other-worldly and sting-free exhibits are just the ticket.

If any of my friends in the Northern Hemisphere are feeling a little blue about the waning of summer, here is a panoply of blue wildlife to uplift your spirits.

Birds this blue sometimes blend into the greenery; but I have spotted them from far across an opposite ridge…gasping from behind my binoculars, such stunning beauty.

We found these blue-headed parrots at a river bank in the Amazon. They were busy extracting minerals from the clay soil.

The color blue is a bit complicated when it comes to nature. Peacock feathers, for example, are actually pigmented brown, but their microscopic structure, through light reflection, expresses blues and greens.

Birdnote.org explains it well:

“Unlike many other bird colors, blue is not a pigment but a color produced by the structure of the feathers. Tiny air pockets and melanin pigment crystals in each feather scatter blue light and absorb the other wavelengths. The even finer structure of the feather gathers the bouncing blue wavelengths together and directs them outward.”

 

I think the blue feathers on this Glossy Starling take scattering and bouncing blue wavelengths to a new high.

I’ve noticed some birds sporting blue always seem to be bright, like these two tanager species…

… whereas other blue-pigmented birds can sometimes look gray or black, depending on the light.

These blue-footed boobies are performing a mating dance. The blue pigmentation in their feet comes from carotenoids in their fresh fish diet. The bluer the feet, the more healthy the bird.

How wonderful to have all these blues in the world–so much pigmentation or light or wavelengths or whatever…to celebrate.

Lizard Land — Part 2 of 2

Green Iguana, Belize, native

 

Last week in Part 1 of this series we looked at lizards’ antipredator adaptations, camouflage, and size. Today we look at their skin, and various ways they move, sense, and communicate.

 

For starters, they are gloriously prehistoric. When you watch a lizard, especially the way it moves, it’s almost as if you are watching a dinosaur. The evolution of reptiles dates back 310-320 million years; more info here. 

 

Marine Iguana, Galapagos Islands

Skin. Lizard skin is covered with overlapping scales made of keratin, providing protection from the environment. Scales also help prevent water loss, especially important in hot, dry deserts.

 

This photo shows the textured scales.

Western Fence Lizard, California

 

Tough and leathery, lizard skin is shed as the animal grows; they usually eat it for the minerals.

 

Locomotion.  Lizards live on the ground, in trees, rocks, underground, and even water. Therefore, they move in many different ways.

 

Although there are some legless lizards, most lizards are quadrupedal. Their gait has alternating movement of the right and left limbs, requiring the body to bend–shown in this photo of the Nile monitor.

 

Nile Monitor, Botswana, Africa

 

One of my favorite lizards for their movement is the common basilisk. When alarmed, basilisks rear up on their two hind legs and skitter across the water, earning them the name Jesus Christ Lizard. I’ve seen them run bipedally on the ground as well.

 

This photo demonstrates the basilisk’s muscular hind legs, necessary for bipedal locomotion.

 

Basilisk Lizard, Belize

 

Many species of lizards can effortlessly leap two and three times their body length. Lizards with short legs, like the skink, undulate like a snake.

 

Skink, California

 

Some lizards are extremely fast, while others, especially larger ones, are more languid. In addition, how much sun they have stored in their body is directly relational to speed.

 

The black spiny-tailed iguana (Ctenosaurus similis) is known as the fastest lizard, clocked at 21 mph (34 kph).

Geckos get the prize for hanging upside down. Their adhesive toe pads allow them to adhere to most surfaces.

 

The Asian House Gecko has the broadest distribution of any lizard in the world.

Senses. With over 6,000 species of lizards, there are many variations of how lizards sense their environment–here are a few notable ways.

 

Eyes. Many lizard species, especially iguanas, have a parietal eye, a third eye, on the back of their head. It is photoreceptive and regulates circadian rhythm and hormone production for thermoregulation. Although it does not form images, it is sensitive to light and movement, helpful for detecting predators. The eye is difficult for us to see.

 

A chameleon can steer each eye in opposite directions. Geckos do not have eyelids, so they lick their eyes to keep them clean and moist. Geckos, like monitors, have acute vision.

 

Ears. Instead of external ears, lizards have ear holes or openings. The eardrums, or tympanic membranes, are just below the surface of the skin. These two close-ups clearly show the “ears.”

 

Dragon Lizard, Australia. Ear hole is reddish-brown circle below and left of eye.

 

 

This frill-necked lizard’s ear opening is just right of center photo, in an almost straight line below the eye. Australia.

 

Nose. All lizards, like snakes, have a specialized olfactory system for detecting pheromones or chemical signals. They have a vomeronasal organ (VNO), located in the soft tissue of the nasal septum. When you see a lizard sticking out its forked tongue, as in the photo below, what you are witnessing is the transferring of scent information from the tip of its forked tongue to the VNO.

 

Golden Tegu Lizard with forked tongue out, Trinidad

 

Mouth. Most lizards are predatory and hunt small invertebrates and/or insects. We have lizards to thank for keeping the insect population in check.

 

This western fence lizard had a fruitful day in my backyard. As winged nuptial ants were streaming from a rock fissure, he gorged for at least an hour.

Here in California we are lucky to have the western fence lizard, because ticks that feed on this lizard do not spread Lyme disease. This lizard’s blood kills off the Lyme bacteria.

 

The marine iguana, found only in the Galapagos Islands, forages on algae, kelp and other marine plants. They will dive up to 98 feet (30 m), and can stay submerged for an hour.

 

While underwater, marine iguanas ingest salt. The salt is filtered from the blood and then nasally excreted. We saw many of them squirt salt out their nostrils.

 

This photo shows the marine iguana’s lovable face encrusted with algae (green) and dried salt (white) on it.

 

Marine Iguana, Galapagos Islands

 

As squamates, lizards have movable upper jaws, and some lizards, like the green iguana, have very sharp teeth capable of shredding leaves and even human skin. All lizards have teeth, dentition varies.

 

Communication. Lizards make sounds for courtship, territorial defense, and distress signals. Geckos are the most loquacious lizards, with chirps and squeaks that can be surprisingly loud. Sometimes you’ll hear a lizard hiss, a warning.

 

Other forms of communication include:  various body postures like push-ups and head-bobs, as well as the expansion of the dewlap. Tail-flicking is common in territorial disputes.

 

We found this dapper anole with a bright orange dewlap in a Texas swamp.

 

Green anole, Texas

 

This green iguana below, near a river in Costa Rica where it is native, was nearly five feet long (1.5 m) including the tail. An arboreal lizard, they hunt and bask in the trees and can easily break a fall with their hind legs.

 

This photo shows his crescent-shaped, uninflated dewlap under the neck. Dewlaps are muscle-controlled, and help regulate body temperature; also used in courtship and territorial displays.

Lizards are one of the most diverse and remarkable creatures on this planet; there are 6,000 species living on all the continents except Antarctica. Here are some of my favorites in this two-part series.

 

Although most lizards may seem vulnerable as fairly small, soft-sided creatures, they are hearty and flourishing survivors.

 

It is their antipredator adaptations that have rewarded lizards with success on the planet. Features such as camouflage, self-amputation, venom, and reflex bleeding aid these reptiles in numerous ways.

 

Camouflage. In the Hawaiian tropics, this gecko surprisingly blends into the lush tropical flowers and greenery. We were lucky to find this one on our rental car where it stood out.

 

Gold Dust Day Gecko, Hawaii

 

Here you see the Lobed Chameleon in Serengeti grass…barely noticeable in its camouflaged state. Imagine how many ferocious wild African species could eat this palm-sized chameleon…yet in Tanzania alone there are 100 species of chameleons.

Lobed Chameleon, Serengeti, Africa (in exact center of photo)

 

The chameleon, like many lizard species, changes color to hide from predators. They also have the ability to extend their long, sticky tongue to snap up insects without having to leave their hiding spot.

 

This frisky pair of spiny-tailed iguanas would have escaped our notice if they hadn’t been rustling in their chasing.

 

Spiny-tailed Iguana pair, Belize

 

We found a frill-necked lizard on every tree in this northern Australia eucalyptus forest. Invisible to us at first, the guide pointed them out.

Frill-necked Lizard, Atherton Tablelands, Australia

In addition to camouflaging, the frill-necked lizards have a unique scare tactic. Named for the ruff of skin around their neck, frill-necked lizards can expand their neck skin like the instant opening of an umbrella. They have bones in the frill that form rods extending their ruff, quickly transforming them to be bigger and more fierce.

 

This is a good BBC YouTube video of what the frill-necked lizard looks like when defending. 

 

Self-amputation. Another example of anti-predator adaptation is autotomy or self-amputation. Skinks and small lizards are known for their ability to escape from a predator by this method.

 

If a predator grabs onto their tail, they sacrifice it by ejecting it, and escape, leaving the predator with only a still-squiggling tail. Miraculously, they grow the tail back. It has been found that lizard DNA is responsible for regeneration, involving 326 genes.

 

You can see this lizard with its battle scars: a segmented tail, indicative of regrowth.

Green Anole, Costa Rica; segmented tail indicating regeneration

 

Venom. While most lizards are not harmful, there are a few who produce venom, like the Gila monster, Komodo dragon, and some monitors. Lizard venom has led to ongoing scientific research for medicinal drugs to help with blood clotting, weight loss, and diabetes.

 

Reflex Bleeding. Horned lizards have an antipredator adaptation called reflex bleeding. At least eight species of this lizard can squirt and aim a stream of blood from the corner of their eyes, shooting it a distance of up to five feet (1.5 m). The blood confuses the predator, and is also foul-tasting to dogs and cats.

 

Another extraordinary lizard characteristic is thermoregulation. As cold-blooded animals, they rely on the sun for supplying energy to move and function. For this reason, lizards can often be seen basking in the sun.

Basilisk Lizard, Belize, Central America

 

Lastly, lizards vary incredibly in size and shape. This land iguana is one of the largest lizards in the world, weighing up to 25 pounds (11 kg) and measuring 3-5 feet long (0.9-1.5 m).

Land Iguana, Galapagos Islands

 

In contrast, this full adult gecko, aptly named the dwarf gecko, is half as big as a paperclip.

Dwarf Gecko, Belize

 

And finally, as an aficionado of wild lizards, I ask that if you ever seek to purchase a lizard for a pet, please be responsible in purchasing only lizards that are bred in captivity and legally bought and sold. Help keep our wild lizards wild.

 

Solar-generated animals that can change colors, regrow their tail, magically blend into their surroundings, and shoot blood. How incredible is that?

My Favorite River

Elephants in Chobe River

Our California winter this year has been blessed with abundant rain. As I walked in my neighborhood park last week, I marveled at the numerous rivers and streams.

 

I pondered what my favorite river on earth was, thought about it all week.

 

Rivers traverse all the continents. Over the centuries, cities have been founded on rivers for their power. They support large populations, and carry heavy loads of people and products. Rivers are the basis for the growth of civilization.

 

I have known so many rivers. How could I pick just one? Could you?

 

One favorite at the top of my thoughts: the Chobe River in Botswana. A popular watering place for African game. We watched wild dogs celebrating a kill, elephants crossing, and hundreds of ungulates.

Then there is the Zambezi, another favorite. It is immense, and one of its most spectacular features: Victoria Falls.

In Zambia, where the Chobe and Zambezi Rivers converge, we had many lively experiences as we waited for the ferry to cross the river.

And the Luangwa River, a major tributary of the Zambezi, holds the largest concentration of hippos in the world. Native residents share the river with crocodiles and hippos.

Folks who fish rivers can read the water like a book.

 

Across the world in South America is the Amazon; we spent a week on the Madre de Dios River, a tributary.

 

It was buggy and humid in Amazonia, almost uninhabitable. I treasured the time we spent cruising this river, for the cool breeze and mosquito relief; and the myriad of wildlife species.

I have many favorite rivers elsewhere, too. My home country has so many rich riverways. The Yellowstone River, a tributary of the Missouri, brings frigid waters tumbling down from the Rocky Mountains.

Yellowstone Falls

The Colorado River, the Snake, the Columbia…and many more that I have had the opportunity to behold.

Colorado River, CO

In California, my home state, the Sierra Mountains deliver our highly revered water every day. We talk in winter about the snowpack, and every time officials measure the snow levels it makes all the newspapers, because this is the year’s source of survival. Dozens of rivers transport this liquid gold to us.

Deer Creek, CA; in the Sierra Nevada mountains

Drought and fires haunt us, and we revel when it rains.

 

What about the river of my childhood, the Mississippi? I was born and raised in the Midwest, where the Mississippi is integral. I’ve had decades of adventures on this river’s numerous branches.

Could the Mississippi be my favorite?

As I continued to ponder the earth’s rivers, I remembered my times on the Rhine, the Danube, the Thames, the Amstel, and more.

Australian rivers, where I saw the rare Papuan Frogmouth (bird) from a motorboat; and my first wild platypus.

As I walked in the park beneath the California oak trees, I heard rambunctious acorn woodpeckers conversing, and red-tailed hawks declaring their territories.

 

I love it that every day the river here is different depending on the light, time of day, precipitation.

 

It is here that I finally got the answer I was seeking. For today, my favorite river is this one…

 

…where my feet are planted, where my eyes take in the ever-glinting movement, and my spirit is calmed by the whispering waters.

Northern California neighborhood park

This funny little river, a stream, really. Quiet, perhaps unnoticed by some, it is a wealth of life and bliss.

Celebrating Bats

Spectacled Flying Fox Bat, Australia

With Halloween around the corner, a bat celebration is in order.

 

Bats occupy every continent except Antarctica, and represent 20% of mammals worldwide. There are 1,200 different species.

 

Grey-headed Flying Foxes, Sydney, Australia

 

Grey-headed Flying Fox, Sydney, Australia

I have only one memory of bats when I was young, and it was my grandmother getting hysterical because one had somehow gotten into the attic. It was a big thing for us girls, who were repeatedly warned that bats make nests in your hair. We all feared bats.

 

This is a curious memory, because I spent many nights outside, playing, and I am sure they were all around me. But all I remember is the bat in Grandma’s attic and my deathly fear of getting one in my hair.

 

Fortunately I grew up. Fortunately I found the beauty of bats.

Grey-headed Flying Foxes, Sydney, Australia

Grey-headed Flying Fox, Sydney, Australia

Bats have so many outstanding qualities, here are just a few. They…

• navigate by echolocation  — use sound to see.
• are the only mammal who can fly on their own power.
• consume large quantities of pests — up to 1,000 mosquitoes a night.
• are prolific pollinators — over 530 species of flowering plants rely on bats for pollination.

 

Bats — Wikipedia

I often go out in the dark to look at stars and listen for owls. Sometimes a bat will come near me, I feel their flutter. Even though I am a tall pillar in complete darkness, they zoom around me effortlessly. And no, they never get caught in my hair.

 

While traveling, I have had some fantastic bat sightings.

 

In Trinidad we came upon a species in the rainforest that we discovered came out every night from underneath our lodge. Fortunately we found them on the first night, and every night thereafter had the thrill of witnessing their emergence.

 

One whizzed by so fast I didn’t even see it, I just felt the breeze on my ear. A post I wrote about it: Enjoying the Bats. 

 

Long-tongued Bats emerging, Asa Wright, Trinidad

 

Pallas’ Long-Tongued Bat, Trinidad

My favorite place to see bats, however, is in Australia, because they have megabats on that continent. Big bats called Flying Foxes.

 

Megabats are the size of birds and assist in re-seeding forests. These days humans are taking down the forests at devastating rates, so having a mammal actually regenerate the forest is a refreshing change.

I love this Australian Aboriginal cave art drawing of bats, because it’s a great reminder of how long bats and humans have been coexisting on our planet.

So as the sun goes down on Halloween, while you’re out there tricking or treating, keep your eyes peeled on the sky. Look for silhouettes of what the ancients called flittermouse. One of these mammalian marvels is probably out devouring pesky insects, giving you a treat.

Lovable Lizards

Land Iguana, Isabela Isl., Galapagos

There are over 6,000 species of lizards on our planet, residing on all continents except Antarctica.  Here are some basic facts and photos of a few of my favorites.

 

One thing I love about lizards is their adaptability. Depending on the severity of danger, they can sacrifice their tail and grow a new one, change colors, and vanish in an instant.

Green Iguana, Costa Rica

Another thing I love is their solar power. Lizards are ectotherms, they require heat sources outside their body to function. Also known as cold-blooded (not technically accurate), lizards regulate their body temperature according to the sun.

 

Once in awhile I will find a lizard when the sun has been absent, like at dawn on a foggy day, and they are frozen in place. Immobile. I like this about lizards, too — their vulnerability. Of course, that’s not their favorite thing.

 

There are many remarkable features about lizards, read more here:

Lizard Wikipedia

 

Green Anole, Texas

 

Basilisk Lizard, Belize, Central America

With six thousand lizard species, there are thousands of variations. I have watched lizards run across water, eat algae under water, flare out their neck to twice its size, and hang upside down for days.

 

Some lizards change colors to attract mates, some change colors to escape detection (camouflage), and others are bright their whole life.

I live in a hot, dry climate in California. In the spring and summer we have three regular lizard species, each is a home-time favorite and much revered.

Western Fence Lizard, California

The western fence lizard is the most prevalent, we see them every day from May through October. The male does push-ups and displays a brilliant blue belly during breeding season.

Plus, this lizard has an astonishing feature. They have a protein in their blood that kills the bacterium in the tick that causes Lyme’s Disease.

 

Ticks often feed on lizards’ blood, including the deer tick that carries Lyme’s Disease. When the deer tick feeds on the western fence lizard, the bacterium is killed. My chances of getting Lyme’s Disease are considerably less because of this  lizard.

 

We also have the alligator lizard, named for their resemblance to alligators. They are skittish and infrequent, but when they appear, it is a highlight of the day.

Northern Alligator Lizard, California

Our third reptile is the western skink. They are almost always hidden, their predator list is long. I’ve learned to recognize their sound when they rustle beneath leaves; so if I wait nearby, I sometimes see them.

 

Western skink, Calif.

 

Some lizards, like the skink, move like a snake. They have short legs and wiggle and slither. But most lizards are quadrupedal and move with an alternating gait. Another thing I love about lizards…watching them walk or run, a kind of reptilian sashay that says “attitude” to me.

Nile Monitor, Botswana

 

The marine iguana, the only underwater lizard in the world, lives on the Galapagos Islands. I’ve been snorkeling when they entered the water–that’s a strange thing, to be snorkeling with a large lizard. A true thrill. They sneeze out the sea salt when they return to land.

Marine Iguana, Galapagos

Lizards bask in the sun, leap through the air, let go of their tail if it’s in the jaws of a predator, and effortlessly change colors. I wouldn’t mind having all of these features, but since I cannot, I’m happy to watch…maybe I’ll learn something.
