Difference between Lizard and Gecko
Geckos are also able to pop off their tail when startled or in danger. This works as a distraction, as when the predator is distracted with the tail, the gecko can get away. Their tail often grows back. Sometimes, their tail heals while another one also grows, leading to a gecko having two or even three tails at a time. However, most other types of lizards are actually unable to regrow their tails. Unlike most other lizards, geckos do not have eyelids, but rather membranes which they must lick to keep them clean and moist.
Another difference between lizards and geckos is the fact that unlike most other types of lizards, geckos are nocturnal, which means that they sleep during the day and come out at night to hunt. Geckos primarily hunt and eat various types of insects such as mosquitos, moths, cockroaches, etc. Whereas, the diet of lizards is varied depending on their species. It may include vegetables, fruits, insects, rodents, small mammals, etc. The Komodo Dragon, which is one of the largest lizards, has been known to stalk, kill and feed on humans on occasion.
Fun fact, the name gecko comes from the Malay word gekoq, which tries to imitate the sound that geckos make. Most other types of lizards do not actually make any sound.
