Vertebrates

Today we learned about how animals are classified into groups. Animals are either vertebrates (which means they have a spine) or invertebrates which don't have a spine).

Vertebrates are put into five groups. The are mammals, birds, fish and amphibians. Mammals have fur or hair and give birth to live young.Birds have feathers and lay hard eggs. Reptiles are cold-blooded and lay soft eggs. Amphibians breathe through their skin and need to keep their skin moist. Fish breathe through gills and have fins.

5 examples of each type:
Mammals:Cow, Horse, Bear,Dog, Human
Reptiles: Snake, Lizard, Alligators, Turtle
Amphibians: Newt, frog, toad, salamander and a caecilian
