Range
All oceans except the high Arctic
Cuvier's beaked whale has a small head, short indistinct beak and sloping forehead. Adults are variably brown to grey, often heavily scarred; adult males have two teeth at the tip of the lower jaw. Its streamlined form is specialized for deep diving (NOAA Fisheries).
It occurs in deep offshore waters worldwide except the high Arctic, especially near continental slopes and submarine canyons. It feeds mainly on deep-water squid and fish and is capable of exceptionally long, deep dives. Underwater noise and ingestion of marine debris are recognized threats (NOAA Fisheries). It is Nationally Least Concern (Thailand Red Data 2025).
