Habitat
True's beaked whales inhabit deep, offshore waters of the North Atlantic Ocean, typically in areas with depths exceeding 1,000 meters. They prefer temperate to subpolar regions and are rarely found near coastal areas, making them pelagic and difficult to observe.
Diet
True's beaked whales primarily feed on deep-water squid and fish such as lanternfish. They use echolocation to hunt in the mesopelagic zone, diving to depths of over 1,000 meters during nighttime or early morning feeds.
Behavior
True's beaked whales are highly social, often traveling in small groups of 2-10 individuals, and are known for their deep diving behavior to avoid predators and forage. They are elusive and spend most of their time submerged, surfacing briefly for air, which makes them hard to study in the wild. Their activity patterns are mostly crepuscular, with increased surfacing around dawn and dusk, and they show little territorial behavior in their vast oceanic range.
Conservation Status
True's beaked whales are listed as Data Deficient by the IUCN, with population trends unknown due to their deep-sea habitat. Major threats include bycatch in fishing gear and noise pollution from military sonar and shipping.
