An attack on a strap-toothed whale. Orcas are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas. [1] In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. [2]
Tilikum was the largest orca in captivity. [8] He measured 22.5 feet (6.9 m) in length and weighed about 12,500 pounds (5,700 kg). [9] His pectoral fins were 7 feet (2.1 m) long, his fluke curled under, and his 6.5-foot-tall (2.0 m) dorsal fin was collapsed completely to his left side.
The rate of orca-boat interactions and their dispersal prompted the formation in August 2020 of a working group for the issue, the Atlantic Orca Working Group (Grupo de Trabajo Orca Atlántica; GTOA). [1] A Facebook group, Orca Attack Reports, was created to facilitate the sharing of information about the interactions. [24]
In a paper published this month in the scientific journal Ocean and Coastal Management, the scientists argue that what humans see as attacks are actually older orcas training the younger ones on ...
Orcas are ‘picky eaters’ known to attack fellow apex predators to devour their livers, experts say
Of the very few confirmed attacks on humans by wild orcas, none have been fatal. [190] In one instance, orcas tried to tip ice floes on which a dog team and photographer of the Terra Nova Expedition were standing. [191] The sled dogs' barking is speculated to have sounded enough like seal calls to trigger the orca's hunting curiosity.
The swiftness of the attack may reflect Starboard’s skill and efficiency as a predator, which could be a response to the stress of spending time hunting close to shorelines in areas where humans ...
Kasatka was the matriarch of the San Diego Orca SeaWorld family. [5] She was the first captive cetacean to successively receive artificial insemination, according to John Hargrove, a trainer there. [6] [7] She bore two daughters and two sons, resulting in six grandchildren and two great-grandchildren by the time of her death:
