Habitat
Hubbs' beaked whales inhabit deep oceanic waters of the North Pacific, preferring areas with depths greater than 1,000 meters and cooler temperate to subarctic regions. They are often found far from shore, over continental slopes and abyssal plains, avoiding shallow coastal areas.
Diet
They primarily feed on deep-water squid such as those from the family Gonatidae, as well as fish like myctophids and possibly shrimp. Feeding occurs during deep dives that can reach over 1,000 meters, using echolocation to locate prey in the dark ocean depths, typically at night or during twilight hours.
Behavior
Hubbs' beaked whales are typically found in small groups of 2-6 individuals, possibly family pods, and are highly elusive with long deep dives lasting up to an hour. They exhibit social behaviors like coordinated swimming and vocalizations for echolocation, but are not known to be territorial. These whales are rarely seen at the surface, making them difficult to study in the wild.
Conservation Status
Hubbs' beaked whales are classified as Data Deficient by the IUCN due to insufficient data on population size and trends. Major threats include potential entanglement in fishing gear and noise pollution from military sonar, which may affect their deep-diving behavior.
