ÖÖobjective science for conservationÖÖ.

The Pacific WildLife Foundation is a non-profit coastal and marine research and education society  that inspires an appreciation for objective scientific research and conservation of the ocean. We conduct original research, develop novel education programs, and inspire an appreciation for conservation of the ocean.

Cuvierís Beaked Whale Ziphius cavirotris

Cuvierís beaked whale is a member of an unusual group of about 20 species of toothed or bottlenose whales. New species are being added to the list and the taxonomy of the group is uncertain. They have a beak shaped nose and most species have a only a pair of teeth that erupt in the lower jaw of males. It varies in color from slate grey to dark brown. Head and back of mature males are silvery grey. Fighting between males leave many tell-tale scars on the combatants. Cuvierís beaked whales travel in small pods of under 10 individuals. It is shy around boats and is an oceanic species. Little is known about its ecology or social organization. Cuvierís beaked whale inhabits the deep ocean outside the polar regions (Wilson and Ruff 1999). It makes long deep dives of three quarters to hour duration to depths as much as 1450 meters (Baird et al. 2005).
