The killer whales regularly demonstrate their competence by chasing seals up shelving gravel beaches, up to the edge of the water.

Men flensing a whale in California, circa 1901. The skills learned from processing drift whales, such as flensing (stripping the blubber), may have led to seeking out live ones.

It reaches a length of 14.9 meters (49 ft), a weight of up to 41 tonnes (90,000 lb) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age.
Hvaldimir, the beluga whale and alleged Russian spy, was killed by gunshots, animal rights groups OneWhale and NOAH said Wednesday amid an autopsy.
The previously mentioned antarctic blue whale holds the title of the biggest animal on earth. It can weigh up to 400,000 pounds and reach a length of 98 feet. The giant’s heart is the size of a car.
Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the
