Red list

show/hide words to know

Scientific name: the Latin name used by scientists around the world to describe a particular plant or animal. Scientific names have two parts. The first part describes the genus, or group of related species. The second part describes the specific species. Example: Acromyrmex versicolor is the scientific name for the leafcutter ant. There is only one scientific name for each plant or animal and scientific names are always italicized.

Species: typically a group of organisms that are so similar that they can interbreed (have offspring)... more

The Red Book List

Take a look at the common and scientific names on the 1964 list (below). Can you tell which is the common name and which is the scientific? One of the first things you should notice about the scientific names is that some of the species have two names while other have three. The ones with three names are not just species, but a small group within species called a "subspecies."

The complete 1964 list of endangered species is below. The list contains the common and scientific names that scientists used back when the list was first made. In some cases the names have changed since they were first listed. In other instances the name is the same. For example the common and scientific name of the American Alligator has not changed. In the case of the Puerto Rican Parrot it was considered to be a subspecies in 1964 (it had three names) and is now considered a full species (with only two names).  Several species on the list below are linked to the Encyclopedia of Life (EOL) followed by an explanation of how its name has changed from then to now. Once you see how names can change, try using EOL to look up other species to see if they also have changed.

Ivory billed woodpecker

A recent debate over the spotting of the Ivory Billed Woodpecker shows that it is not always easy to know when the last of a species is gone.
