Cuvier’s beaked whales feed at incredible depths, up to 3,000 meters, and most feeding occurs near the seabed. They use suction feeding to capture prey, that include a wide variety of squid (at least 47 different species!) and sometimes deep-sea fish and crustaceans. Studies show that they use echolocation for foraging mostly below 500 m.
Since they live in deep waters, spending a lot of time underwater for feeding, Cuvier’s beaked whales are hard to find because they spend only short periods at the surface to breathe. They are typically found individually or in small groups (2-7 whales). Males are the most likely solitary animals. They are very sensitive to anthropogenic noise and tend to avoid vessels, but they can be quite inquisitive in some areas, including the Mediterranean Sea.
Lifespan and reproduction
Cuvier’s beaked whales reach sexual maturity usually between seven to eleven years of age for both sexes. Breeding and calving can occur year-round, peaking in the spring. After a year of gestation, females give birth to a single calf every two to three years. Newborn are bluish-grey or brownish on the upper side. They are about 2,7 m long and weight 300 kg. They have an estimated lifespan of up to 60 years.
