False Killer Whale

False Killer Whale

A pod of about 40 false killer whales showed up alongside the Orange County coastline on Saturday, March 20, a rare sighting for the tropical species usually found in hotter waters. Abundance estimates of false killer whales in Hawaiian waters and the broader central Pacific. Amanda L Bradford, EA Becker, EM Oleson, KA Forney, JE Moore, and J Barlow. Due to their dangerous effects on fisheries, humans kill false killer whales. In some regions in the eastern tropical Pacific, they are hunted for meat.

Adult females reach lengths of 16 ft, while grownup males are almost 20 toes long. Whale strandings are rare in southern Africa, but mass strandings on this area are sometimes associated with the false killer whale, with mass strandings averaging at 58 individuals. Hot-spots for mass strandings exist along the coast of the Western Cape in South Africa; the latest in 30 May 2009 close to the village of Kommetjie with fifty five people. In a number of Japanese villages, the false killer whale is killed in drive hunts using sound to herd people together and cause a mass stranding or corral them into nets earlier than being killed. The false killer whale reaches physical maturity between 8 and 14 years, and most age in captivity is 57 years for males and 62 for females.

The name “false killer whale” comes from the similar skull traits to the killer whale . They are identified to leap out of water and perform flips on special occasions such as social occasions. The species is so called due to having similarities with the orca of killer whale.

  • Females of this species often feed their offspring, holding a fish in their mouth whereas the calf eats the prey.
  • Until 1861, when the first carcasses washed up on the shores of Kiel Bay in Denmark, the species was thought to be extinct.
  • The Commission submitted comments supporting the proposed crucial habitat designation, but noted that the proposed designation was overly broad.
  • This might additional constrict the already limited gene circulate within the main Hawaiian Islands insular false killer whale inhabitants.

It is not fully understood as to why the two species hang out together but theories embody evasion from predators and improving foraging success. They have been observed catching a fish of their mouth whereas completely breaching the waters’ surface. They have also been seen shaking their prey until the head and entrails are shaken off. They then peel the fish utilizing their enamel and discard all of the pores and skin earlier than consuming the stays.

Restoration Planning And Implementation

False killer whales in HawaiĘ»i, particularly primary Hawaiian Islands insular false killer whales, have a excessive rate of dorsal fin injuries and mouthline accidents, doubtless caused by efforts to take bait and catch from fishing traces. The false killer whale is a member of the family Delphinidae, the oceanic dolphins. It is part of the subfamily Globicephalinae, and its closest dwelling relations are Risso’s dolphin, the melon-headed whale , the pygmy killer whale , the pilot whales (Globicephala spp.), and presumably the snubfin dolphins (Orcaella spp.). One subspecies was proposed by Paules Edward Pieris Deraniyagala in 1945, P. c. meridionalis, although there was not enough justification, and William Henry Flower instructed in 1884 and later deserted a distinction between northern and southern false killer whales; there are at present no acknowledged subspecies.
