Amphibians vs. Reptiles

By: Inaara Jiwani

Amphibians

Amphibians live two lives meaning they live on land as well as water. Amphibians usually have to stay near water sources to prevent drying out, and have smooth skin. They breathe with their gills and lungs, and they're cold blooded. Their forms of defense include toxic skin secretions and biting. They have no nails, and if teeth are present, they are pedicellate teeth. They have short fore limbs and long hind limbs with five webbed digits. Their skin is smooth, moist and sometimes rather sticky skin. Laden with mucous glands. Their eggs have soft, gel surroundings without any hard covering. Usually, they are found in water or damp places. Some examples include frogs, toads, newts, salamanders, etc.

Reptiles

Reptiles are groups of animals that breathe air, have scales on their bodies, and lay eggs. They breathe with their lungs, and their cold blooded. Their forms of defense include nails and teeth (some have venom; Gila monster, beaded lizard, and many snakes). Reptiles have scales, which act as a sort of armor to physically defend the body. Reptiles usually have four limbs, but some reptiles have no limbs, such as snakes. Reptiles with limbs vary in their ability to move; some move very slowly and crawl, while others can run, jump, and even climb. One type of lizard can even run on water. Their skin is dry and scaly, and the scales are made of keratin. The skin is found underneath the scales. The eggs have hard, leathery coatings laid on land, or they keep eggs in their bodies until they hatch. Some examples include snakes, lizards, crocodiles, turtles, etc.
