Lizards are a group of animals under the category of reptiles. In other words, lizards are cold-blooded reptiles that have long tails and four legs. They are the biggest group of reptiles moving around with the abdomen facing the ground. The skin of lizards is covered in overlapping scales made of keratin. Some animals developed ways to extract water from their food but the desert dwelling lizards don’t drink water. These lizards absorb water through their skin. They draw fluid up against the pull of gravity. They absorb water and keep water in and out. When the lizards are wet, they would raise their bodies and lower their heads. Lizards use gravity to channel the water down towards their mouths.
