ACME Mapper is a website that works similarly to Google Maps or Yahoo Maps. The difference is that you can type in locality information that would translate unclearly using more traditional mapping websites. Example "0.9 km SxSE of Boone NC on US 321". ACME Mapper is a great tool for looking up locality information for a field book entry or collected specimen.
All About Birds
This website was created and is maintained by the world renowned Cornell Lab of Ornithology to provide public and professional science enthusiasts with all you could hope to know about North American birds. Their database includes information on identification, calls, distributions, and natural histories for every avian species that occurs in North America. You can even download a bird identification app to your smart phone to help you identify birds on your own birding adventures.
AmphibiaWeb is a one-stop resource for nearly anything you want to know about the conservation, taxonomy, and biogeography of the 7,405 described frogs, salamanders, and caecillians of the world. All species accounts typically contain historical and current distributions, life history traits, identification tips, conservation concerns, and lots of pictures of these amazing organisms.
Encyclopedia of Life
Encyclopedia of Life is website devoted to make biodiversity science information available to the public. By simply searching for a specific species or group of species, EOL will generate a large list detailing all the etomology, taxonomy, biogeography, and natural history available for every group of organisms found on our planet.
FishBase is a global information system dedicated to linking researchers and educators interested in the study of fish; the most biodiverse group of vertebrates on the planet. The website allows you to search nearly every fish species that have been described by scientists. Included in each search are a number of tools to help identify fish, confirm new localities, and learn about the natural history of this fascinating group of animals.
The Integrated Digitized Biocollections (iDigBio) is a national resource for Advancing Digitization of Biodiversity Collections (ADBC); a program funded by the National Science Foundation (NSF). This website allows you to search through biological collections (zoological, botanical, mycological, and microbial) from a great variety of institutions throughout the United States. After registering with iDigBio, the website will allow you to search for any specimen in the iDigBio databases accompanied by pictures, maps, and data. If you are interested in biological collections this is the greatest source of information for biodiversity education, research, and archival.
Integrated Taxonomic Information System (ITIS)
The Integrated Taxonomic Information System website was created through a partnership of several federal agencies to make an easily accessible database with reliable, up to date taxonomic information for all described flora and fauna of the world. By searching a species or genus name the website will inform you if the name you are using is still valid and, if it has changed, what the most widely accepted classification is.
North Carolina Museum of Natural Sciences
The North Carolina Museum of Natural Sciences is one of the largest natural history museums in the Southeastern United States. The research and collections portal allows you to search through the entirety of their inventory of zoological, geological, paleontological, and astrological collections and view distributions of specimen localities.
A project funded by the National Science Foundation (NSF) to make vertebrate biodiversity data available from museums and zoological collections around the world. By simply searching for a species or group of species, VertNet will generate a list of all specimen recorded in their database, a distribution map of specimen localities, and pictures of specimen often accompanied by morphometric data. This is a fantastic tool for anyone interested in vertebrate diversity education or research.
