Characteristics of the Five Vertebrate Groups. Fish. The body of the fish is covered in scales and has fins attached to help it move through the water. Fish breathe using gills which take oxygen out of the water.When male and female fish mate, the eggs often meet the sperm in the water.This is called external fertilization. Examples of fish are the herring, which lives in the sea, and the pike which is a freshwater fish.Amphibians.

This is unique in the vertebrate world, because fish, reptiles, birds, and mammals are all born as small versions of the adult, not a completely different form. This dual life, one aquatic with gills and one terrestrial with lungs, may be representative of the evolution of animals out of water and onto dry land.hen you are a vertebrate, too! Vertebrates make up most of the animals that we are familiar with. Exceptions to this would be things like an insect, an octopus, a lobster or crab, a jellyfish, or a clam. Most everything else is a vertebrate, with a backbone and other bones.
