13 Reasons Why Orcas Should NOT Be Kept in Captivity!

SeaWorld announced in that it would stop breeding whales in captivity immediately and phase out killer whale shows at all its parks by In San Diego, the shows ended in The company has said, however, that the shape of a killer whale's dorsal fin is not an indicator of its health. While less likely, it is not impossible for a wild orca's dorsal fin to collapse or become bent, and it may be a trait that varies among whale populations. A study of killer whales in New Zealand showed a relatively high rate — 23 percent — of collapsing, collapsed, or even bent or wavy dorsal fins. This was higher than that observed in populations in British Columbia or Norway, where only one male from the 30 studied had a fully collapsed dorsal fin, the study said.

In , the dorsal fins of two male killer whales collapsed after exposure to oil during the Exxon Valdez oil spill—the whales' collapsed fins were thought to be a sign of poor health, as both whales died soon after the collapsed fins were documented. Researchers have theorized that dorsal fin collapse in wild whales may be due to age, stress, injury, or altercations with other killer whales. Alves, F, et al.

They are incredibly social, diverse and ferocious marine predators with a diet ranging from penguins to great white sharks. Orcas are the largest members of the dolphin family. Males are bigger than females, but they vary in size and weight, depending on the type of orca.

The largest orca ever recorded was a staggering 32 feet 9. That's longer and heavier than most motorhomes. Orcas are known for their long dorsal fin the fin on the animal's back and black-and-white coloring. The black-and-white coloring helps to camouflage them by obscuring their outline in the water. Just behind the dorsal fin is a patch of gray called a "saddle" — because it looks like a riding saddle. An orca's body is cylindrical and tapers at each end to form a hydrodynamic shape.

Orcas have massive teeth, which can grow up to 4 inches 10 centimeters long, according to National Geographic. Orcas are apex predators, at the top of the food chain. No animals hunt orcas except for humans. Killer whales feed on many different types of prey, including fish, seals , sea birds and squid. They can also take down whales larger than themselves, such as minke whales, and they are the only animal known to predate on great white sharks, according to The Natural History Museum in London. Killer whales have even been reported to kill swimming deer and moose , according to a chapter on orcas in " Primates and Cetaceans " Springer, Orcas use many different techniques to catch prey.

Sometimes they beach themselves to catch seals on land, jumping from the water onto land. They can use echolocation to identify their prey by creating sounds, or sound waves, that travel through the water. These waves echo off objects, including prey, which the orcas can use to locate them, according to SeaWorld. There is no record of an orca ever killing a human in the wild. This is because humans are not part of their natural diet.

Occasionally, an orca may mistake a human for something they do eat, such as a seal. In , an orca was caught on camera charging at a surfer during the Lofoten Masters surfing competition in Norway. The orca seemed to pull out of the attack just before making contact. The Norwegian Orca Survey said in a Facebook post that the orca likely realized the surfer was not a seal at the very last second. In , a year-old boy was "bumped" by a killer whale near Ketchikan, Alaska, in what may have been an aborted attack — similar to the surfer in Norway — or simply curiosity on behalf of the orca, according to the Associated Press, via The Seattle Times.

The Associated Press reported that a surfer was bitten in California in the early s, which is the only relatively well-documented case of a wild orca actually biting a human. Orcas in captivity, however, have attacked and killed people. Although wild killer whales do not intentionally harm people, they have attacked boats. There were many reports beginning in the summer of of orcas ramming into and causing damage to sailing boats off the coast of Spain and Portugal, according to BBC News. Three juvenile male orcas were involved in most of the attacks, and marine biologists investigating the incidents believe that the young males were playing with the boats by targeting the rudders and pushing the boats around. Orcas are very social creatures and live in family groups called pods, which have up to 50 members, according to the University of Michigan's Animal Diversity Web ADW.

These pods are made up of related mothers and their descendants, known as matrilines. A male orca will stay with its mother for life, while daughters may spend time away after having calves of their own, according to the wildlife charity Whale and Dolphin Conservation WDC. Pods often have their own distinctive calls, or dialects, to communicate, but they will associate with other pods and can come together to form even larger, temporary groups. A female killer whale will give birth to one offspring at a time every three to 10 years. The gestation period usually lasts for around 17 months according to SeaWorld. Orcas work together to take care of the young, and other females in the pod will often help with the rearing.
