What kind of animals are in the phylum Chordata?
The Phylum Chordata is made up of many Classes. • Mammalia (Mammals) • Amphibia(Amphibians) • Aves (Birds) • Osteichthyes (Fish) or Actinopterygii (ray-finned fish) • Reptilia(Reptiles) • Chondrichthyes(Sharks & Rays) Order The Class Mammalia is broken down into 2 subclasses: • Prototheria(monotrenes – like duck billed platypus)
