[8] They can be trained in captivity and are often described as intelligent,[9] although defining and measuring "intelligence" is difficult in a species whose life is very different from ours.[9].
Killer whales, or Orcas (Orcinus orca) are toothed whales in the oceanic dolphin family.
Unique dialects. The largest Orca (killer whale) ever recorded in a bok was a male, off the coast of Japan, measuring an astonishing 9.8 m (32 ft) and weighed over 8 tonnes (17,636 lb).
That distinction goes to the blue whale (Balaenoptera musculus), the largest animal on Earth.
[3][10] Some orcas have discovered that flipping sharks upside down can paralyze them.
Orcas have mostly black skin with white patches.
[11] Once, fishermen placed their boats several miles apart, taking turns retrieving small amounts of their catch, in the hope that the whales would not have enough time to move between boats to steal fish as it was being retrieved. How strong is a blue whale? About 380 whales have died in what is suspected to be Australia's largest stranding on record, officials say. In 1997, the first known killer whale attack on great white sharks was documented off the coast of San Francisco.
[2] Their behaviour and hunting techniques also differ. They are easy to identify because of their distinctive white and black colouring.
When it comes to their diet killer whales have been known eat fish, cod, herring, mackerel and squid, and in some cases they will also consume larger prey such as large squid, sea lions, walruses, seals, sharks, birds, turtles and even large whales.
Some marine parks now require trainers to stay outside the pool when they work with orcas. “We would still have focused our efforts on Fraser Flats because they are the ones with the best chance of survival.”.

Every pod has a unique dialect of sounds. They have been known to attack baleen whale calves, and even adult whales. In captivity, dorsal fins often collapse for many reasons, but in the wild, dorsal fin collapse happens in less than one percent of wild orcas. In addition to whales there are also several large species of dolphin that inhibit the ocean.
That's taller than most grown men. The stranding is likely one of the largest on record globally, the worst in Australia’s history and one of the largest globally.

[3] Females are smaller, generally ranging from 5 to 7m and weighing about 3 to 4 t.[3] The largest male killer whale on record was 9.8 metres, weighing over 10 tonnes, while the largest female was 8.5m, weighing 7.5 t.[4] Calves at birth weigh about 180 kilograms (400 lb) and are about 2.4 metres (7.9 ft) long.
They are found in all the world's oceans, from the cold of the Arctic to the tropical seas. Mitochondrial sequence divergence among Antarctic killer whale ecotypes is consistent with multiple species. The largest individual killer whale ever recorded was a male that measured 9.8 m (32 ft 1 in) from head to tail and weighed more than 10 tonnes (22,050 lb) – nearly as heavy as two fully grown African elephants!
It was 27 m (89 ft) long with a weight of 90 tons, although the reliability of this information is unconfirmed.

There are several different types of Orca, each of which has different living and prey habits. Records show some 294 whales, also long-finned pilots, stranded at Stanley on Tasmania’s north-west in 1935. They do not interbreed and seems to be subspecies or even separate species.
