False Killer Whale

The false killer whale reaches a maximum length of 6 m , though dimension can differ around the world. It is extremely sociable, identified to type pods of as much as 500 members, and can even type pods with other dolphin species, such as bottlenose dolphins . Further, it could type close bonds with different species, in addition to partake in sexual interactions with them. Conversely, the false killer whale has additionally been recognized to feed on other dolphins, although it usually eats squid and fish. It is a deep-diving dolphin, with a most recorded depth of 927.5 m ; its maximum velocity is round 29 km/h .

There have been solely three few massive-scale surveys in Hawaiian waters, and modifications in survey design make it difficult to determine trends in abundance for this pelagic population. The most important risk to false killer whales in Hawaii is interactions with fishing gear that lead to critical damage or dying. False killer whales are interested in fishing vessels, where they take bait and hooked fish, corresponding to mahi-mahi and yellowfin tuna. Consequently, they’re generally caught on hooks or entangled in fishing strains. Found in open waters all through the tropics and sub-tropics, notably surrounding the Hawaiian Islands, false killer whales are considered naturally rare, regardless of being high on the food chain. One of essentially the most plentiful populations of false killer whales could be discovered offshore from Hawaii and contains roughly 1,550 people.


See the false killer whale sections in chapters on Species of Special Concern in previous Marine Mammal Commission Annual Reports to Congress. They feed on large pelagic fishes, corresponding to mahi-mahi, tuna, wahoo, and often share their catch with other whales in their teams. These whales will eat fish off of fishing strains and out of nets of commercial fishing operations.

  • False killer whales are usually found in tropical and temperate waters between latitudes of 30° and 30° N.
  • This population was listed as endangered beneath the Endangered Species Act in 2012.
  • i-based deep-set and shallow-set longline fisheries, NOAA Fisheries established a take discount group.
  • We also offered support for a research to compile and analyze associated organic information.
  • The false killer whale easily adapts to captivity and is kept in several aquariums around the world, though its aggression towards other dolphins makes it much less desirable.

To distinguish these species, bottlenose dolphins have beaks, and pilot whales are bigger with obvious dorsal fin differences. Adult males range from 3.7 to 6.1 m in length, while adult females vary from three.5 to five m. This species has a extra slender build in comparison with different dolphins and they have tapering heads and flippers.

Current Conservation Efforts

This affords us the flexibility to switch these actions in real time to reflect changes in the data available as well as progress in the direction of recovery. methods to recuperate the endangered primary Hawaiian Islands insular false killer whale, had been published in October 2020. A final restoration plan and last recovery implementation technique for the main Hawaiian Islands insular false killer whale are anticipated in 2021, as is a 5-12 months status review to find out if the endangered listing is still appropriate. The Hawaiʻi pelagic inhabitants contains false killer whales inhabiting waters more than 11-km (6.8 miles) from the primary Hawaiian Islands, together with adjoining high-seas waters. Despite having partially overlapping ranges, the three Hawaiian false killer whale populations don’t socially work together or interbreed with one another.

This hotline is out there 24 hours a day, 7 days per week for anyone within the United States. If you’re on a vessel and a spinner dolphin approaches you, put the engine in neutral and allow the animal to proceed on its way. If a spinner dolphin is crossing your path, decelerate and move behind it. Disturbing wildlife interrupts their ability to perform crucial capabilities similar to feeding, breeding, nursing, resting, and socializing.
