Chameleons By Luli Tulpan Classification Kingdom: Anamalia
Phylum: Chordata
Class: Reptilia
Order: Squamata
Family: Chamaeleonidae
Genus: Chameleo Species: There are about 160 different species of chameleons. Some of them are....

The tip of a chameleons tongue is larger and really sticky. This way the chameleons pray won't be able to escape. Smaller chameleons usually have longer tongues. To eat and catch prey, chameleons shoot their tongue out of their mouth. Catching prey takes less than a second for a chameleon. Chameleon Camouflage Chameleons can look in two different directions at a time.
Their upper and lower eyelids are joined, and have a hole large enough for only the pupil to see through.
Their eyes move independently, so they can rotate and focus them separately. Only some chameleons can change color The ones who can't are usually just the color of their habitat, like brown or green, or even more exotic colors pink, blue, red, orange, yellow, purple. Then there are chameleons that can change color, but they can't change whenever they feel like it. They change color because of light, temperature, mood, and health.
And unlike what most people think, chameleons don't change whatever color or pattern their background is, each chameleon species has a specific color range based on where that species lives. Scientific Name: Chamaeleonidae

Common Name: Chameleons Can you find the Chameleon? Eyes Predators

Chameleons can't defend themselves very well.

Bigger chameleons become meals for hawks, owls, and other birds.
Smaller chameleons are eaten by spiders and snakes. People

Humans are also a threat to chameleons.

Some people keep chameleons as pets without knowing anything about how to take care of them. Because they are so hard to take care of, chameleons die quickly in captivity. Habitat Loss.

We also destroy their habitat. Some Chameleons live in forests in Africa, which are know being chopped down. Why is this a good adaptation?

they can observe two different objects simultaneously
This gives them a 360-degree arc of vision
Chameleons have bad hearing and sense of smell. So they have to use their eyesight as protection
They have very good eyesight for reptiles, and can see small insects from 5m to 10m . Chameleons are found in warm habitats that vary from tropical or mountain rain forests to desert conditions, savanna, and steppeland

They live in Africa, Madagascar, southern Europe, across south Asia and as far as Sri Lanka.

They've been introduced to Hawaii, California, and Floria.

Some Chameleons live in trees or bushes, but others live on the ground, or in low vegetation.
On each foot, chameleons have five toes which are connected together in two groups, a group of three and a group of two.

This gives each foot a tongs-like appearance.

On their front feet the outer group has 2 toes and the inner has 3. Their back feet are reversed.

Their special feet allow them to grip tightly on to thin or rough branches.

each toe has a sharp claw at the end, which helps grip onto tree bark and other surfaces. Feet Some species, like Smith's dwarf chameleon, adjust their color for camouflage according to the vision of the specific predator (bird or snake) that they are being threatened by.

The Namaqua Chameleon lives in the desert. This Chameleon changes color for thermoregulation. It becomes black in the cool morning to absorb more heat and turns a light gray to reflect light during the heat of the day. Sometimes it shows both colors at the same time, neatly separated left from right by the spine. Chameleons might not have a future. Sadly some species of chameleon endangered and are threatened by extinction. There numbers are declining mainly because of deforestation What will they look like in the future? I think in the future they will adapt and be able to turn the color of their background. Like if they are on a yellow background, they will instantly turn yellow to become invisible and unseen by predators. I also think they have better hearing, so they can hear predators coming. First of all what is Evolution?

When something adapts to it's environment and gains a specific trait that helps it survive in it's habitat, it passes this adaptation on to it's offspring. Evoloution is when these adaptations are passed on and on through genarations and genaraations, until the whole species has evolved so that all individuals now have this trait. Basically they will look the same, (with better hearing) except you will never be able to see them because they will have awesome camoflauge. what species are chameleons related to? There are more than 160 different types of chameleons. So of course all chameleons are related to each other.
They are also related to other scaled reptiles, (snakes and lizards) like iguanas, but not closely. Tails Chameleons have a long prehensive tail, which they use for climbing and balance.
At night, when the chameleon sleeps, the tail curls up into a perfect spiral. Some species have a crest of small spikes extending from their neck to their tail.
These spikes break up the outline of the chameleon, which helps it to blend in to a background. Spikes Diet

Chameleons eat only insects, which they catch with their long and sticky tongue How have chameleons evolved over time?

Chameleons have change over time. Before they had the adaptations to change color or have really long toungues, chameleons probably looked different.

The oldest known chameleon is Chamaeleo caroliquarti a species that lived about 26 million years ago, we know this from fossil records.
