As apex predators, killer whales have few enemies, vulnerable only to large sharks. Their fierce reputation comes from interactions with whales, not humans. In fact, sailors who witnessed killer whale attacks on larger cetaceans referred to the animals as "whale killers." That name changed to ...
We also observed shifts in the spring arrival of killer whale calling over the time period of the study, which correlated with the timing of sea ice retreat. Killer whales shifted their time of arrival an average of 50days earlier in the North Slope region and 32days earlier in the Bering...
Orcas were originally called "whale killers" because ancient sailors saw them hunting in groups to take down large whales. Over time, that name morphed into "killer whales." Killer whales are apex predators, which means they're at the top of the food chain and no animals (other than humans...
Arctic sea ice has provided a historical barrier for killer whale (Orcinus orca) entry, but that barrier is now depleting as the sea ice melts due to global climate change. This study used passive acoustic monitoring to describe changes in broad-scale killer whale presence in the U.S. Arctic...
Killer Whales But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators. ... If you had
Orca, killer whale (Orcinus orca) Orca – king of the oceans Killer whales are the ocean’s largest and most dangerous predators. They have a characteristic black and white coloration, which makes them difficult to confuse with other species. Like dolphins, of which they are very close relativ...
3 Killer robots would confer enormous military advantage to states with access to them, and a correspondingly destructive potential against the enemies of those states. For this reason, many people on either side of the argument see the development and deployment of killer robots...
hunting skills and voice communication of killer whales are considered as evidence of their own culture. They are predators, fierce temperament, good at attacking prey, penguins, seals and other animals are natural enemies. Sometimes they attack other cetaceans, even great white sharks, which can ...
As ecosystem-based fishery management becomes more prevalent, trade-offs between conservation objectives for predators and prey will become increasingly necessary. Our approach offers scenarios to compare relative influence of various sources of uncertainty on the resulting consumption estimates to prioritise ...
