The Phalacrocoracidae family of birds is represented by 38 species of cormorants and shags. Several different classifications of the family have been proposed recently, but in the one most commonly used, all but two or three species are placed in a single genus Phalacrocorax, the exceptions being the Kerguelen Shag, the Imperial Shag, and (sometimes) the Galapagos' Flightless Cormorant.

The Cormorant is a project currently under development at Lockheed Martin's Skunk Works research facility. It is named after a species of bird.
