Characteristics of Animals Vertebrate Animals ·Animals are made up of more than one cell, they are multicellular. ·Animals cannot make their own food, so they must eat other organisms allowing them to move on their own during part or all of their lives. ·Animals with backbones are vertebrates, it protects nerves that go to the brain. ·Five classes of vertebrates are mammals, reptiles, birds, amphibians, and fish. last paragraph pg. 10 Vertebrate Animals First paragraph pg. 10 Characteristcs of Animals

Mammals Reptiles Birds ·All mammals breathe air with lungs, have hair or fur all over their bodies, and are warm-blooded. ·They keep their body temperature almost the same all the time and they usually look like their parents at birth. ·The mothers make milk for their babies. ·Reptiles have tough, dry skin with scales, are cold-blooded and their blood temperature changes. ·Snakes, lizards, and turtles are reptiles and they hatch from eggs and begin looking for food right after birth. ·Dinosaurs were considered reptiles and similar to today’s lizards because most had four legs, scaly skin and have backbones, and are different because dinosaurs legs go straight down and lizards legs go out. ·Birds are warm-blooded vertebrates and their wings have feathers that help them fly. ·Some birds have wings shaped like an airplane’s wings with the front edge of their wing being wide and the top of the wing curving back to a thin edge. ·Not all birds can fly. First paragraph pg. 11 Mammals Reptiles Second paragraph pg. 12 Birds Seventh paragraph pg. 12

Amphibians Fish ·Frogs, toads, and salamanders are amphibians that are cold-blooded and have soft, moist skin that can absorb water and oxygen. ·All amphibians hatch from eggs and when they are young, most of them are tadpoles. -At first, they breathe using gills and as they get older, they grow legs and their tails get shorter. -Eventually they stop breathing with gills and live on land. ·Grown frogs look very different from when they were young, that’s why no other vertebrates change this much in their lifetime. ·Fish are vertebrates that live in water and breathe through gills found on each side of the head. ·Most fish have scales and also have a slimy coating that helps water flow past them.
