Chameleon Behavior and Biology

Chameleons are fascinating creatures with 202 known species, 42 of which reside in Madagascar. They are renowned for their ability to change color, primarily for communication rather than camouflage. This color change can signal attraction, warning, or emotional states like anger or fear. Chameleons also employ unique movement patterns to mimic leaves, aiding in predator avoidance. Their long, sticky tongues allow them to catch prey from a distance. However, many chameleon species are endangered due to habitat destruction. Conservation efforts are underway to protect these unique reptiles.
