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.
Article from Wikipedia describing the complex terminology necessary to be used when describing the anatomy of animals in order to avoid confusion.
Notes by Michael J. Farabee on the structure and functions of each of the four major animal tissue types: epithelial, muscle, connective and bone.
Homeostasis describes the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues and organs.
Outlines the evolutionary history of animal groups from the simple coelomates to the chordates and the various vertebrate classes, with diagrams and photographs.
Abstract from an article studying a variety of regulatory mechanisms that determine the sex of offspring in the animal kingdom.
Article from Wikipedia describing the characteristics, functions and types of bone and how bone is formed.
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.
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.
Information on the invertebrate members of the phylum Chordata, what they have in common, and the characteristics of the two subphyla, Urochordata and Cephalochordata.
Educational and research resource with sections on ichthyology, herpetology, ornithology and mammalogy.
Information on the research and programs being undertaken at the Smithsonian Museum of Natural History.
Provides an index to animal sounds on the Web including birds, mammals, reptiles, amphibians, fish and insects.
In this article, Michael Laurin outlines the anatomy and evolution of the outer, middle and inner ear in land vertebrates.
Uses infrared photography to show the differences between warm and cold blooded animals.
Outlines the differences between the subphylum Vertebrata and the two subphyla, Urochordata and Cephalochordata.
Michael Laurin outlines the life history of tetrapods and extinct terrestrial vertebrates.
Searchable database of specimens that includes over 50,000 tissue samples for use in molecular analyses.
Comprehensive list of the technical terms you are likely to come across, with cross references.
Clips recorded by Doug Von Gausig of the sounds made by various amphibians, reptiles, mammals and birds.
Provides a comprehensive list of definitions of the technical terms likely to be met when studying the vertrebates.
Outlines the function of this system, its anatomy and physiology, and compares the mammalian organs with those of birds, amphibians, reptiles and fish.
Stegocephalians are tetrapods with digits rather than fins. Michael Laurin explores the relationship between the extant and the extinct members of this group.
Illustrated description of these three phyla, and the three classes within Urochordata. Also information on the larval stages which form part of the plankton.
Abstract from a paper comparing the sensory systems of vertebrates with the less-developed systems of Amphioxus.
Describes the principle characteristics of tetrapods, which have well defined joints and digits, their classification and phylogenetic relationships.
Details of this year’s meeting of SVPCA and abstracts from presentations made in previous years.
These notes cover the dermis and epidermis including skin, beaks, nails, hooves, horns, hair, feathers, scales and teeth.
Notes on the classification structure of the Vertebrates with a cladogram to review the evolutionary relationships of the craniata.
Features images and measurements of mammalian skulls as well as updates and related links.
