Offshore orcas, first described in 1979, are primarily found more than 10 miles (16 km) from shore. Just over 280 offshore orcas are known from the Eastern North Pacific, primarily occurring off the coast of British Columbia.
Offshore: A third population of orcas in the northeast Pacific was discovered in 1988, when a humpback whale researcher observed them in open water. As their name suggests, they travel far from shore and feed primarily on schooling fish . [ 25 ]
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
[4] [5] For example, a large marine vertebrate may eat smaller predatory fish but may also eat filter feeders; the stingray eats crustaceans, but the hammerhead eats both crustaceans and stingrays. Animals can also eat each other; the cod eats smaller cod as well as crayfish, and crayfish eat cod larvae. The feeding habits of a juvenile animal ...
BY PHUONG LE SEATTLE (AP) -- Scientists studying Puget Sound orcas for the past decade now know they are among the most contaminated marine mammals, with pollutants particularly high in young ...
Since liquid water flows, ocean waters cycle and flow in currents around the world. Since water easily changes phase, it can be carried into the atmosphere as water vapour or frozen as an iceberg. It can then precipitate or melt to become liquid water again. All marine life is immersed in water, the matrix and womb of life itself. [7]
Water depth and the type of habitat — rocky, sandy or coral reef — also played roles in the approaches the whales took. Drone imagery shows a gray whale using a side-swim technique to find food.
A group of people fishing in South Florida waters expected to sea turtles, manatees, conch and perhaps a shark — but this time, whale, you can say they were in for a huge surprise.
