Habitat
These whales inhabit deep, offshore waters of the Southern Hemisphere, including areas around South Africa, Australia, and New Zealand, typically in temperate to subantarctic regions. They prefer depths greater than 1,000 meters and are rarely seen near coasts. Their pelagic lifestyle means they are most often encountered in open ocean environments.
Diet
Strap-toothed beaked whales primarily feed on deep-water squid and fish, using suction feeding during prolonged dives to depths of over 1,000 meters. They likely hunt at night when prey is more abundant in the upper water column. Feeding behavior involves echolocation to locate prey in the dark ocean depths.
Behavior
These whales are highly elusive and typically travel in small groups of 2-10 individuals, often including mother-calf pairs. They are deep divers, capable of staying submerged for over an hour, and exhibit behaviors like logging at the surface to rest. They are not territorial and avoid boats, making them difficult to study in the wild.
Conservation Status
The IUCN status is Least Concern, though data is deficient due to the species' elusive nature; population trends are unknown but potential threats include entanglement in fishing gear and noise pollution from shipping. Conservation efforts focus on reducing bycatch and monitoring ocean noise impacts.
