How Well Do You Know The Chameleon?

The correct answer is "Reptilia" because alligators are reptiles. Reptilia is the class that includes reptiles such as alligators, snakes, lizards, and turtles. Reptiles are characterized by their scaly skin, cold-blooded nature, and ability to lay eggs on land. Alligators specifically belong to the order Crocodilia within the class Reptilia. They are large, semi-aquatic reptiles found in freshwater habitats and are closely related to crocodiles.

The distinctive feature of a chameleon is its ability to change color. Chameleons are known for their remarkable camouflage abilities, allowing them to blend in with their surroundings and avoid predators. This unique characteristic is achieved through specialized cells in their skin called chromatophores, which contain pigments that can expand or contract to create different colors. By adjusting the size and distribution of these pigments, chameleons can change their appearance in response to various environmental factors such as temperature, light, and mood. This ability to change color is not found in most other animals, making it a defining characteristic of chameleons.

Stereoscopic vision refers to the ability to perceive depth and three-dimensional objects. It is a special characteristic of their eyes because it allows them to have a greater sense of depth perception and accurately judge distances. This is achieved by the brain combining the slightly different images seen by each eye, resulting in a three-dimensional perception of the world. Stereoscopic vision is particularly advantageous for activities such as hunting, as it helps in accurately judging the distance and position of prey.

Chameleons are fascinating creatures known for their unique adaptations, including a prehensile tail for gripping branches, independent eye movement for a wider field of vision, and color-changing skin for camouflage and communication. However, they are not venomous. Their bite is harmless to humans and is primarily used for catching insects and other small prey.

A special feature of a chameleon's feet is that they are zydodactylous. This means that they have two toes facing forward and two toes facing backward, which allows them to have a strong grip on branches and other surfaces. This unique foot structure helps chameleons to navigate their environment and climb with ease.

Brookesinae is the correct answer because they are the subfamily of chameleons. The question is asking who divided the chameleons into two subfamilies, and Brookesinae is one of those subfamilies. Therefore, it can be inferred that Brookesinae is the correct answer.

Chameleons are commonly referred to as old world lizards because they are native to Africa, Madagascar, and parts of the Middle East and southern Europe. They belong to the family Chamaeleonidae, which is a group of reptiles characterized by their ability to change color, long tongues, and unique eye movements. Chameleons have adapted to their specific habitats and are known for their camouflage and specialized hunting techniques. Therefore, the term "old world lizards" accurately describes chameleons.

The correct answer is 1986. This suggests that whatever "it" is, it was classified in the year 1986.

Chameleons change color by using specialized cells called chromatophores that contain pigments. These pigments are controlled by the chameleon's nervous system and can be expanded or contracted to create different colors. However, the guanine crystals in their skin also play a role in color change. These crystals reflect and scatter light, creating iridescent colors. So, the correct answer is "The guanine crystals."

Chameleons catch flies using all of the mentioned methods. They are known for their ability to change their skin color to blend in with their surroundings, which helps them camouflage and approach their prey unnoticed. Additionally, chameleons have a long, sticky tongue that they can shoot out rapidly to catch insects like flies. So, their catching mechanism involves a combination of camouflage, the use of their sticky long tongue, and their colorful skin.
