What types of resources does Animal Diversity Web offer?

Updated

Animal Diversity Web (ADW) is a species-information resource hosted by the University of Michigan. Its main offerings are text-based species accounts, a browsable classification of major animal groups, and a search interface that can filter results by media type — pictures, specimens, sounds, and maps. The site is in English and is organized around taxonomy rather than around a single region or habitat.

Species accounts and classification

The core of the site is descriptive information about animals, reached either by searching or by browsing the classification tree. The homepage lists major groups directly, which gives a quick sense of the scope:

Group Common name
Actinopterygii ray-finned fishes
Amphibia frogs, salamanders, and caecilians
Annelida segmented worms
Aves birds
Chelicerata chelicerates
Chondrichthyes rays, sharks, and relatives
Cnidaria jellyfish, sea anemones, corals, and relatives
Crustacea crustaceans
Echinodermata starfish, sea urchins, and relatives
Insecta insects
Mammalia mammals
Mollusca bivalves, cephalopods, snails, and relatives
Nematoda roundworms
Platyhelminthes flatworms
Porifera sponges
Reptilia turtles, snakes, lizards, and relatives

If you already know the animal's scientific or common name, searching is faster than walking the tree. If you only know the broad group — say, "some kind of flatworm" — browsing from the group list is the practical route.

Media and specimen resources

ADW is not only text. The search interface lets you restrict a query to specific content types, and the homepage names them explicitly:

  • Everything — searches across all content types at once
  • Information — the written species accounts
  • Pictures — images associated with species
  • Specimens — specimen records
  • Sounds — audio recordings
  • Maps — distribution maps
  • Topics — subject-based entry points

This matters when your goal is narrower than "tell me about this animal." For example, if you need a distribution map for a report, selecting Maps before searching avoids paging through text you don't need. If you're looking for a sound recording to compare calls, selecting Sounds does the same.

How to search effectively

  1. Go to the search box on the homepage.
  2. Enter one or more keywords.
  3. Optionally select a content type (Everything, Information, Pictures, Specimens, Sounds, Maps, Topics) to narrow the results.
  4. Run the search.

The site supports phrase searching with quotation marks. The homepage gives the examples wombats and "gray wolves" — the quoted form treats the words as a single phrase rather than two separate terms. The homepage also points to a Search Guide for additional tips, so if a query returns too much or too little, that guide is the place to check before assuming the site lacks the content.

What to expect and where it fits

ADW is best treated as an educational and reference source on animal diversity and classification, produced in an academic context. It is a reasonable starting point for school assignments, background reading on a group, or locating a picture or map tied to a species. It is not a live biodiversity database with occurrence records, and the homepage does not present it as one — the emphasis is on descriptive accounts and taxonomy.

One practical limitation to plan around: because content is organized taxonomically and by media type, a search that is too broad (a common name shared by many species, or a single genus name) can return a long list. Adding a second keyword or switching the content type usually narrows it faster than scrolling.
