Cystophora is a genus of just one species (a “monotypic” genus) within the true seal family of nineteen species: the Hooded seal (also known as Bladdernose seal).
Together with the families of Eared seals and Walruses, True seals form the group of marine mammals known as Pinnipeds.
The hooded seal derives its name from the male's ability, when mating, excited, or threatened, to close one of his nostrils, an inflate its trunk. The inflated trunk forms a crest or a hood on top of the head.

The Author
The Encyclopedia of Life (EOL) is an ambitious, even audacious project to organize and make available via the Internet virtually all information about life present on Earth. At its heart lies a series of Web sites—one for each of the approximately 1.8 million known species—that provide the entry points to this vast array of knowledge. The entry-point for each site is a species page suitable for the general public, but with several linked pages aimed at more specialized users. The sites spark ... (Full Bio)
