Signs Of Aggression

The hissing of chameleons is characterized by a wide range of emotions, such as fear, anger, and stress. When your chameleon hisses, it means you should back away. It is the most prominent sign of aggression towards the owner and other people.

Hissing is used as a defensive mechanism to scare predators. All species of chameleons follow this strategy to protect themselves from their predators. Veiled is the most common type of chameleon that hisses in captivity.

Owners should behave sensibly and compassionately toward their chameleons. Your chameleon may also hiss if it is not feeling well or if it is sick.

Injured toes/feet, eye infections, and other illnesses can lead to discomfort that can increase aggression.

Color Change

Chameleons are popular reptile species known for their color-changing traits. Many people think that chameleons change their color to camouflage their background, but this is a misconception.

The primary reason chameleons change color is to regulate their body temperature and communicate with other chameleons.

Generally, they use bold color changes for communication purposes. A male chameleon will change its bright color to dark color in threatening scenarios.

It becomes easier for owners to determine the mood of their pet chameleons based on their skin colors. When your chameleon is stressed, it would change its color to black or dark brown.

Some species change their skin colors to dark red when they feel angry or anxious.

A panther chameleon in normal situations has green or blue skin color with a white horizontal stripe. When it gets angry, the chromatophores organized in layers expand red color that blocks out the blue and green colors.

Staring with Both Eyes

Both eyes of a chameleon have independent sight mechanisms. However, when one eye sees the prey, it will send a message to the other eye to focus on the prey.

Chameleons do not use both eyes (stereopsis) for depth perception. Most often, a chameleon usually relies on its monocular vision to perceive things.  

In simple words, chameleons’ eyes have a unique structure and anatomy that allows them to have a 360-degree vision. However, monocular vision is changed into binocular vision when they feel any danger or threats in the surrounding environment.

It is an incredible ability of the chameleon to make a transition between monocular and binocular vision. It is due to the location of the eyes on the head – i.e. each eye is located on the opposite side of the head.

Anyway, if you try to pick up or handle your chameleon, you will notice that it stares at you with both eyes. When you notice this, you must carefully place the pet back into its cage and leave it alone.
