Amphibians typically live in watery habitats and arthropods live in dry habitats. There are, however, a number of snakes who dont lay eggs at all and instead give live birth (just like mammals!). Dry and full of scales made up of a protein called keratin. The majority of all amphibians found in the United Kingdom are frogs and toads. In animals that contain coelomic fluid instead of blood, oxygen diffuses across the gill surfaces into the coelomic fluid. So, snake and lizard shaped creatures are reptiles and everything else is an amphibian, right? The two atria receive blood from the two different circuits (the lungs and the systems).
