Animals with backbones. Animals with backbones or vertebrates are classified into 5 subgroups. Fish is the largest of vertebrates.. FISH. Breathe through a set of gills. Covered with hard scales. Reproduce by laying soft, non-shelled eggs. By: Haya Al . Rabban. What are Vertebrates?. Vertebrates are animals that have backbones like Fish, Amphibians, Reptiles, Birds and Mammals . Fish. Fish have slimy bony scales for protection and . They also have gills for breathing. They get thousands of eggs and they don’t worry about the eggs.. Page: 500 - 519. Phylum Chordata. Classification.
