Orcas (or killer whales) 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]
On average, an adult killer whale in the wild may eat about three to four percent of their body weight daily, [82] or as much as 227 kg (500 lb) of food for a six-ton male. Their diet in the wild depends on what is available, and may include fish, walruses, seals, sea lions, penguins, squid, sea turtles, sharks and whales. [ 83 ]
Although resident orcas have never been observed to eat other marine mammals, they occasionally harass and kill porpoises and seals for no apparent reason. [106] Some dolphins recognize resident orcas as harmless and remain in the same area. [107] Orcas do consume seabirds but are more likely to kill and leave them uneaten.
Killer whales have no predators -- except for humans. Documentaries like 'Blackfish' reveal the exploitation behind whale captivity. In the late 1960's, Famous orca Shamu was the whale who set the ...
A stoat surplus killing chipmunks (Ernest Thompson Seton, 1909) Multiple sheep killed by a cougar. Surplus killing, also known as excessive killing, henhouse syndrome, [1] [2] or overkill, [3] is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then they either cache or abandon the remainder.
The orcas interacted with the yacht for 45 minutes, bumping against the blade of the rudder, causing damage and leaks. No humans were harmed and the vessel sank near the entrance to the port of Tanger-Med. [14] [7] On 12 May 2024, the Spanish yacht Alboran Cognac was attacked by orcas and holed. Both people on board were rescued by a tanker.
A man-eating animal or man-eater is an individual animal or being that preys on humans as a pattern of hunting behavior. This does not include the scavenging of corpses, a single attack born of opportunity or desperate hunger, or the incidental eating of a human that the animal has killed in self-defense.
The herring population is not completely depleted by orcas because they never eat the whole herring ball during the feeding phase of carousel feeding. [2] The herring that are not consumed are able to escape from the orcas. This means the orcas do not completely deplete their food source and potentially the strongest herring will survive the ...
