Scaly skin, no fur, and a favorite warm rock to sit on. Turn the page and meet the reptiles.
A snake is covered in scales, and they are dry, not slimy. They are made of keratin, the same stuff as your fingernails. The wide flat scales along a snake's belly work like the treads on a boot and grip the ground.
Chameleons do not change color to match the wallpaper. Each kind has its own set of colors and patterns it can show, and it swaps between them depending on how warm it is, how bright the light is, and how it is feeling. A calm chameleon and a grumpy chameleon are different colors.
A tortoise cannot climb out of its shell, because the shell is part of its skeleton. It is built from about sixty bones joined to the tortoise's backbone and ribs. So a tortoise wears its ribs on the outside.
Reptiles are ectothermic, which means their warmth comes from outside them instead of from inside. You make your own heat all day long. A lizard borrows its heat from the sun, so it lies on a warm rock until it is toasty and ready to move.
