Educational and research resource with sections on ichthyology, herpetology, ornithology and mammalogy. |
Clips recorded by Doug Von Gausig of the sounds made by various amphibians, reptiles, mammals and birds. |
Outlines the evolutionary history of animal groups from the simple coelomates to the chordates and the various vertebrate classes, with diagrams and photographs. |
Notes by Michael J. Farabee on the structure and functions of each of the four major animal tissue types: epithelial, muscle, connective and bone. |
Comprehensive list of the technical terms you are likely to come across, with cross references. |
Homeostasis describes the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues and organs. |
Information on the invertebrate members of the phylum Chordata, what they have in common, and the characteristics of the two subphyla, Urochordata and Cephalochordata. |
These notes cover the dermis and epidermis including skin, beaks, nails, hooves, horns, hair, feathers, scales and teeth. |

Uses infrared photography to show the differences between warm and cold blooded animals. |
Provides a comprehensive list of definitions of the technical terms likely to be met when studying the vertrebates. |
Though primarily designed to protect the brain, the architecture of an animal’s skull can help scientists to deduce many of its dietary and social patterns. |
Lecture notes on the characteristics of the Phylum Chordata and the further characteristics of the classes of animals in the Subphylum Vertebrata. |

In this article, Michael Laurin outlines the anatomy and evolution of the outer, middle and inner ear in land vertebrates. |
Describes the principle characteristics of tetrapods, which have well defined joints and digits, their classification and phylogenetic relationships. |
Michael Laurin outlines the life history of tetrapods and extinct terrestrial vertebrates. |
Stegocephalians are tetrapods with digits rather than fins. Michael Laurin explores the relationship between the extant and the extinct members of this group. |
Most tetrapods breathe with the lungs that they inherited from their ancestors such as the coelacanth and lungfishes and this is probably also true of extinct groups of stegocephalians. |
