Habitat
Cuvier's beaked whales inhabit deep offshore waters, typically beyond the continental shelf in depths greater than 1,000 meters. They are found in all major oceans except the polar regions, preferring temperate and tropical zones with access to steep underwater slopes.
Diet
They primarily feed on deep-sea squid and fish, such as lanternfish and cuttlefish. These whales perform extremely deep dives, often exceeding 1,000 meters, to hunt their prey using echolocation, typically during the day or night when prey is available.
Behavior
Cuvier's beaked whales are usually found in small groups of 2 to 7 individuals, though they can be solitary. They are deep divers, capable of holding their breath for over 2 hours and diving to depths of 3,000 meters, making them elusive and rarely seen at the surface. They exhibit shy behavior around boats and are not territorial, with movements influenced by prey availability.
Conservation Status
The IUCN status is Least Concern, but populations face threats from military sonar, which can cause strandings, and entanglement in fishing gear. Overall population trends are uncertain due to their deep-water habitat.
