ORCA: KILLER WHALE OR WHALE KILLER

On Wednesday, an Orcinus Orca, reportedly killed 40-year-old Dawn Brancheau, a trainer at SeaWorld in Florida US.

There are conflicting reports on exactly how the incident happened.
A spectator said that the Orca came out of the water, grabbed the trainer by the waist and dragged her under.
The sheriff’s report states that Brancheau was rubbing the Orca’s head when she slipped and fell in the water.

Tillikum, or Tilly as he is commonly known, is usually kept isolated from other whales, and trainers are not allowed to get in the water with him, because he has a history of being violent.

The whale was blamed for the drowning of one of his trainers in 1991 while he was performing at Sealand of the Pacific in British Columbia.
Sold to SeaWorld as a stud in 1992, the whale was involved in a second incident when authorities discovered the body of a naked man lying across his back in July 1999.

So, how much do we really know about killer whales?

Firstly, Orcinus Orca – named after Orcus, the Roman god of death and the underworld - is not a whale at all.
Orca is the largest of the dolphin family, and one of the world’s most powerful predators, sporting teeth that are up to 10cm long. They can grow to up to ten metres in length and weigh up to six tonnes.

Orcas’ reputation as fierce hunters comes in part because they frequently target other marine animals, regardless of size.
They hunt in groups, much like wolves, and commonly eat whatever's convenient -- seals, sea lions, squid, fish, birds, other whales and dolphins.

Imagine the bloody scene of a pack of killer whales devouring something as large and notorious as a great white shark, which is also on the killer whales' takeout menu.

But killer whales do not hunt humans. There is no record of Orca, in its natural habitat, ever attacking a human.
In fact, whalers claim that Orcas helped them hunt other whales.
They used to refer to them as ‘whale killers’, and somewhere along the line, perhaps through an error in translation, it got switched around to ‘killer whales.’

Why then does Tilly attack humans?

Animal rights advocacy group People for the Ethical Treatment of Animals has for years been calling on SeaWorld to stop confining ocean-going mammals to an area that to them is like the size of a bathtub.

‘It comes as no surprise when these huge, smart animals lash out’ PETA said in a statement.
Wouldn’t you lash out after being kept in a bath tub for 30 years?
