False Killer Whale
Acoustically monitoring the Hawaiʻi-based longline fishery for interactions with false killer whales. Establishing a take discount staff and publishing a take discount plan to reduce bycatch of Hawaiian false killer whales in industrial longline fisheries. The small dimension of the endangered primary Hawaiian Islands insular false killer whale inhabitants poses a unique menace to this group.
Adult females reach lengths of 16 toes, while grownup males are almost 20 feet lengthy. Whale strandings are rare in southern Africa, however mass strandings on this space are typically associated with the false killer whale, with mass strandings averaging at 58 individuals. Hot-spots for mass strandings exist alongside the coast of the Western Cape in South Africa; the latest in 30 May 2009 near the village of Kommetjie with 55 people. In a couple of Japanese villages, the false killer whale is killed in drive hunts utilizing sound to herd people collectively and cause a mass stranding or corral them into nets earlier than being killed. The false killer whale reaches bodily maturity between eight and 14 years, and maximum age in captivity is fifty seven years for males and 62 for females.

Main Hawaiian Islands insular false killer whales, the population we all know essentially the most about, move widely, quickly, and often all through the principle Hawaiian Islands. The biggest offshore movements occur on the leeward sides of the islands, the place people tend to spread out over a lot bigger areas, each close to and much from shore. When on the windward sides, people focus closer to shore, heavily using areas within the 1,640- to 3,937-ft depth vary, notably north of Hawaiʻi Island, Maui, and Molokaʻi.
- Adult females attain lengths of sixteen feet, whereas adult males are almost 20 toes lengthy.
- Full-grown adult male false killer whales can attain lengths up to 20 toes lengthy and weigh almost three,000 kilos.
- Time between births is unknown, but is estimated to be around 7 years.
- They are most carefully associated to Risso’s dolphins and pilot whales, rather than killer whales as their name suggests.
False killer whales are identifiable by their rounded heads, small dorsal fin and dark gray bodies. They are most closely related to Risso’s dolphins and pilot whales, rather than killer whales as their name suggests. Playful and active, false killer whales are fast swimmers and might regularly be seen browsing the bow waves of vessels or poking out of the water.
Restoration Planning And Implementation
False killer whales in Hawaiʻi, significantly major Hawaiian Islands insular false killer whales, have a high rate of dorsal fin accidents and mouthline accidents, likely caused by efforts to take bait and catch from fishing strains. The false killer whale is a member of the family Delphinidae, the oceanic dolphins. It is part of the subfamily Globicephalinae, and its closest living family members are Risso’s dolphin, the melon-headed whale , the pygmy killer whale , the pilot whales (Globicephala spp.), and possibly the snubfin dolphins (Orcaella spp.). One subspecies was proposed by Paules Edward Pieris Deraniyagala in 1945, P. c. meridionalis, although there was not adequate justification, and William Henry Flower instructed in 1884 and later abandoned a distinction between northern and southern false killer whales; there are at present no acknowledged subspecies.
