This category is for sites about the study of organisms in the Phylum Craniata (our phylum), Phylum Cephalochordata and Phylum Urochordata. Included in this category are the vertebrate classes fish, amphibians, reptiles, mammals and birds.
Reptiles are cold-blooded, air-breathing vertebrates having the skin covered with scales. The class includes tortoises, turtles, lizards, snakes and the Crocodilia. Amphibians are cold-blooded vertebrates with smooth skin. The class includes salamanders, frogs, toads and newts. Herpetology is the scientific study of reptiles and amphibians.

Fish are cold-blooded, aquatic vertebrates breathing by means of gills and having fins supported by skeletal rods called fin-rays. The class includes the bony fishes and the cartilaginous fishes. Ichthyology is the scientific study of fish.
Mammals are warm-blooded vertebrates which suckle their young and which have a covering of hair. Mammalogy is the scientific study of mammals.

Birds are warm-blooded, feather-bearing, egg-laying, amniotic vertebrates having the fore-limbs modified into wings. Ornithology is the scientific study of birds.
