Vertebrate
Vertebrates are members of the
subphylum Vertebrata (within the phylum
Chordata), specifically, those chordates with
backbones or
spinal columns. About 57,739
species of vertebrates have been described. Vertebrata is the largest subphylum of chordates, and contains many familiar groups of large land animals.
Fish (including
lampreys, but traditionally not
hagfish, though this is now disputed),
amphibians,
reptiles,
birds, and
mammals (including
humans) are vertebrates.
