Geckos are cool-looking little lizards that live in hot places. Like all reptiles, they can’t regulate their body temperature so they rely on the sun to keep them warm.
They live mostly in deserts, rainforests and jungles.

Geckos can be as small as 1 inch or as large as 1 foot long. Their tails are fat. Geckos store food in their tails. If you grab a gecko by the tail, the tail will come off so the gecko can escape.
