Zoology – Animal Life

Major Zoological Resources

The Zoological Record : Zoology on the Internet might well begin here. Extensive links about Biocomplexity, Biodiversity, Biological Informatics, Codes of Nomenclature, Directories of Biologists, Systematics, Taxonomy & Nomenclature resources, Internet resource guide to Zoology (subject index and animal index)

Zoology Guides below are from the Zoological Record site and here modified and expanded for links to various animal groups.

Online Encyclopedia of Life : This database holds information on over 50,000 species, from humpback whale to eastern hemlock, with endangered status, distribution, life history, and references.

World Biodiversity Database: Already boasts entries for some 200,000 species of plants, fungi, animals, bacteria, and protists, drawing from 39 taxonomic surveys and projects on groups such as marine mammals, sea cucumbers, and the orchids of New Guinea.

Oceanlink : Find answers to over 550 questions about marine biology; from seaweed to sharks, whales to whelks, and marine pollution to oceanography. Topics include Northwest Pacific Biodiversity, Tides, Animals, The Deep Sea, Marine Food Webs, Underwater Acoustics, an Intertidal Field Guide, and more.

Diatoms: With their delicate, ornate cell walls made of silicon dioxide, the aquatic protists called diatoms rival the work of the world's best jewelers. Sift through a taxonomic databases and other resources of the California Academy of Sciences, whose glass menagerie includes more than 59,000 samples.

Protozoa: Microbes were the only living things for most of the history of the Earth. Over 3.5 billion years ago they began the process of transforming this planet, making it habitable for those who came later. This site has images of microbes, classification schemes, descriptions of organisms, talks and other educational resources.

Mammals – That's Us, Too

Class Mammalia : All mammals share three characteristics not found in other animals: 3 middle ear bones; hair; and the production of milk by modified sweat glands called mammary glands.

The Primates : All of the ~300 or more species of primates are classified into one taxonomic order because they are mammals with close evolutionary roots. The exact number of living primate species may not be known. Every few years new ones are found. In fact, a team of scientists has discovered Three New Species of Mouse Lemurs, the world’s smallest primates, living in the endangered forests of Madagascar.

Primate Brain Information System : For neuroscientists baffled by the many alternative names given to similar central nervous system structures in different species, BrainInfo offers welcome relief. The site sorts out 6500 names and synonyms for about 860 structures and gathers information on them from various databases.

Duck-Billed Platypus Facts : Little is known about the ancestry of the platypus. But fossils have been found that seem to show that the platypus had ancestors which had similar attributes. It is suggested that the platypus developed as a result of therian mammals (metatherians and eutherians) diverging over 180 million years ago.

Mammals and Birds of Latin America & Caribbean : Lists over 5500 species and includes info on endangered status, distribution maps, and scientific and common names in English, Spanish, and Portuguese.

African Elephant Is Two Species': Researchers say there is genetic evidence to show that Africa's elephants form two separate species. The difference between the two is more than half the genetic distinction between African and Asian elephants.

Panda Clone Could Save Species: Chinese scientists say they have successfully produced an embryo clone of a giant panda, and are hoping that it will now develop to maturity. They are hailing it as a possible breakthrough in their efforts to save one of the world's most endangered species.

Endangered Species Cloned: Some researchers believe cloning may offer the only way to save species from extinction. But conservationists argue there is little point if the reasons for the animals' decline, such as habitat loss, have not been addressed first.

New Help for Threatened Bats: Scientists say almost half the world's bat species face some degree of threat to their survival and that populations in many countries are experiencing alarming declines. Bat Conservation International and Bat Conservation Trust are to organization to check out.

Bats Revealed as Bird Killers: A rare kind of European bat regularly feasts on birds, surprised biologists have discovered. And they suspect that the large bats are capable of hunting down the birds in flight, something no researcher has ever seen.

Cetacea: Bone up on your knowledge of whales, dolphins, and porpoises at, a collection of backgrounders on all 81 known species of cetaceans. The streamlined accounts deliver the basics on appearance, classification, behavior, food, and habitat.

Primates in Print: Need to find the most recent studies on the social life of the Philippine tarsier, a bug-eyed, spindly-fingered primate dwelling in that country's tropical rainforests? How about Jane Goodall's early papers on nest building in wild chimpanzees? This is a well-stocked bibliography of primate books, papers, reports, abstracts, and dissertations.

Tapir Gallery: Get oriented with species accounts that cover the range, habits, and distinguishing marks of the four living species, which inhabit tropical areas of Asia and Central and South America. The well-stocked pictures section contains snapshots along with artwork and other images.

Birds of the World

Class Aves : Birds are vertebrates with feathers, modified for flight and for active metabolism. Birds are a monophyletic lineage, evolved once from a common ancestor, and related through that common origin.

Bird Skulls  An internet resource with good illustrations of more than 800 bird skulls. Be sure to look at the animated images of complete bird skeletons.

The Internet Bird Collection: More than 8000 videos of bird species of the world. They currently have 25% of all living species represented.

New Bird Species in USA : New Gunnison Sage Grouse identified through genetics. It's vocalization is different, too.

Tiny Gnatcatcher Poses Big Conundrum : A study of DNA from the threatened California gnatcatcher and the abundant Baja (Mexico) gnatcatcher has shown no differences that would place the two birds in different subspecies. Therefore, destroying the California bird's habitat through development will not threaten the species, or any subspecies, as a whole.

Digital Recordings from Nature! : Bird, Insect and other animal sounds. North American and Costa Rican birds. Also Bats, Whales, Squirrels and Rattlesnakes.

Tardigrades : The tardigrade, sometimes called water bear or moss piglet, is a microscopic organism, of arthropod-like appearance, but so physiologically unusual it has a phylum all its own.

Mites and Ticks: Don't look now, but something is creeping through your eyebrows: tiny mites that even a shower won't dislodge. Although the denizens of your eyebrows are benign, other kinds of mites suck the life out crops. The varroa mite, a recent invader from Asia, has devastated beehives across the United States.
