What is that Tongue Doing?

I have lived with many iguanas over the years, but Stella, a green iguana, is the only one who constantly sticks her tongue out. I’m always afraid I’ll startle her and she’ll cut her tongue with her razor sharp teeth. Fortunately, that has never happened. Her tongue is intact. 

So, why is her tongue always sticking out? She’s tasting or “smelling” the world around her. Iguanas don’t smell with their noses like people do. They “taste” the world. Scent particles in the air are collected on the tongue, then brought into the mouth. The particles are analyzed by special sensory cells for identification. These cells make up the Jacobson’s or vomeronasal organ. If you watch an iguana walking, you’ll see her flicking her tongue out. If something is particularly interesting, say a tasty bit of food, the tongue flicks back and forth a lot.

Stella’s forked tongue, with which she “tastes” the world.

Another interesting thing about iguana tongues is that they are forked! Just like a snake’s tongue. You might also notice that the end of Stella’s tongue is darker. That’s because it is more enriched with blood. The better for tasting!

Iguanas are fascinating friends. To learn more about them, check out the Lyric Power Publishing workbook with activity sheets, called My Unit Study on Iguanas.

How Do You Know if a Lizard is a Green Iguana? by Curtis Curly-tail

Hello, out there, friends and fans! It’s me, Curtis Curly-tail!

Today, I wanted to ask you if you knew that Green Iguanas, Iguana iguana, come in different colors? And, if they come in different colors, how do you tell if a lizard is a green iguana? 

You look for the subtympanic scale. “What is that?” you ask. Well, I don’t have one, so I had to look it up myself. The subtympanic scale is that large scale on the side of the green iguana’s head.  Sub means below and tympanic means ear.  So, it’s the big scale below the ear. I have a friend who calls that scale the “jewel.” She always admires the beautiful coloring in the iguana jewels.

Here are some of my green iguana friends, in very different colors. As you can see, they are not just green–but they are all still called “green.” Even the green green iguanas come in different shades of green. It can be confusing, if you ask me.

The native range of the green iguana is southern Mexico to central Brazil and several Caribbean islands. If you don’t live in those areas, why should you know how to identify a green iguana? Because they’re very popular as pets in people’s homes and they have been introduced to many other places in the world, where they don’t belong and can be causing harm. That means they’re “invasive.”

Not Everyone Wants to Be a Star! by Curtis Curly-tail

Hello, friends! It’s me, Curtis Curly-tail! I’m visiting my friend and author of fun science books, Elaine A. Powers. She’s working with Brad Peterson, who is, among other things, a talented graphic artist and animator. He had the idea to educate about reptiles by showing them eating.

Of course, I agreed to help with the videography. (I know—I know what you’re thinking. I love to be in the spotlight, and I do. But, I’m also very curious and I enjoy learning about everything, so I volunteered to be on the filming team.)

As you will see on my YouTube channel Curtis Curly-tail Speaks, many of the family members cooperated.  However, some were shy about being filmed while eating, while others were just plain hostile to the idea.

Turquoise, above, a hybrid green iguana, would not let me film her eating. In fact, she continued to glare at me until I left. And, no matter how I tried to sneak up on her, she wasn’t fooled. That is one alert dragon—I mean, iguana,of course!

Speaking of iguanas, they are awfully large, aren’t they? But quite fascinating. Did you know they don’t have vocal cords and make no sounds?

The Story of a Green Iguana Named Stella

I am an author of both children’s and adult science books, inspired to write about the world of reptiles. I am as ‘at-home’ with reptiles as I am with mammals–perhaps even more so. And I tend to look after the underdogs.

So, when Stella, a green iguana, was found on a street in Bethlehem, PA, with her tail badly chewed, I took an interest in her. The veterinarian thought it was done by dogs, possibly pit bulls owned by drug dealers. Her rescuers had to amputate most of her gorgeous four-foot tail.

Stella’s tail was chewed up and had to be amputated.

Stella was full-sized, uncommon for captive green iguanas. Apparently, she had been cared for up until she was separated from her family. Once she had sufficiently healed from her surgery, they sent her to my rescue center in Highbridge, New Jersey. Her health returned, and she soon moved to her forever home with me.

Despite her injuries, she produced eggs after her arrival. She also tried to regenerate her tail, but the stump had been sewn shut.

She likes to hang out with her buddy, Ezra, another green iguana who lives in a nearby separate enclosure. Ezra likes to stand on his rear legs and show off for Stella every now and then. They’re very attentive to each other.

Stella has developed high blood pressure, as evidenced by a swollen nictitating membrane. It is kept under control with medication.

She is a sweet-natured iguana, and it is my pleasure to have her as a pet in my home.
