Vertebrates and invertebrates.
The vertebrates are further divided into five groups or classes.
Bird and mammals are the only two groups of vertebrates which are warm blooded. Amphibians, reptiles and fish, the other vertebrate groups, are all cold-blooded.
There are five groups of vertebrates; fish, amphibians, reptiles, birds and mammals.
All vertebrates reproduce sexually. Birds are one of the main groups of vertebrates, so they reproduce sexually.

Vertebrates and chordates share fundamental characteristics, as all vertebrates are a subgroup of chordates. Both groups possess a notochord at some stage of development, a dorsal nerve cord, pharyngeal slits, and a post-anal tail. While chordates include a wider range of organisms such as tunicates and lancelets, vertebrates specifically have a backbone or spinal column, which distinguishes them within the chordate phylum. Thus, all vertebrates are chordates, but not all chordates are vertebrates.
