An orca leaps out of the water when swimming—a behaviour known as porpoising—in Hood Canal. Orcas are found in all oceans and most seas. Due to their enormous range, numbers, and density, relative distribution is difficult to estimate, [49] but they clearly prefer higher latitudes and coastal areas over pelagic environments. [50]
Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks ...
Orcas, or “killer whales,” can grow up to 27 feet long and weigh as much as six tons. Known as the ocean’s top predator, they’re extremely intelligent, with their own languages of clicks ...
The killer whales regularly demonstrate their competence by chasing seals up shelving gravel beaches, up to the edge of the water. The pursuing whales are occasionally partially thrust out of the sea by a combination of their own impetus and retreating water, and have to wait for the next wave to re-float them and carry them back to sea.

Coralling is a method where dolphins chase fish into shallow water to catch them more easily. [52] Killer whales and bottlenose dolphins have also been known to drive their prey onto a beach to feed on it. Killer whales have been known to paralyze great white sharks and other sharks and rays by flipping them upside down.
Researchers found an increase in common dolphin sightings in the English Channel and Hebrides, and a decline in white-beaked dolphins in the Hebrides. Human impact on ocean increasing pressure on ...
Orcinus is a genus of Delphinidae, the family of carnivorous marine mammals known as dolphins. It includes the largest delphinid species, Orcinus orca , known as the orca or killer whale. Two extinct species are recognised, Orcinus paleorca and O. citoniensis , describing fossilised remains of the genus. [ 2 ]
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.
