Habitat
This species inhabits deep, offshore waters of the southern Pacific Ocean, particularly around New Zealand and possibly extending to other subantarctic regions. They prefer pelagic environments with depths exceeding 1,000 meters, avoiding coastal areas.
Diet
The spade-toothed whale primarily feeds on deep-sea squid and fish, such as lanternfish, using suction feeding during long dives. They hunt in the mesopelagic zone, likely at dusk or night when prey is more active.
Behavior
Spade-toothed whales are thought to live in small pods of up to six individuals, exhibiting social behaviors similar to other beaked whales. They are deep divers, capable of remaining submerged for over an hour to forage, and are generally elusive, avoiding boats and surface activity. Little is known about territorial behavior due to their rarity and deep-water habits.
Conservation Status
The IUCN status is Data Deficient due to the species' rarity and lack of sightings. Major threats may include bycatch in fisheries and underwater noise pollution, though population trends are unknown.
