What is the killer whale?
Killer Whale, Orcinus Orca is not actually a whale, but the largest member of the Dolphin family. These black and white mammals are the only known predator of large white sharks and are often used as exhibiting animals in sea parks. Research conducted since the end of the 20th century has determined that the killer whale is divided into at least three groups so different that they can qualify as different species. Although some variants have been recorded, most kilometers have a black back and hips with a large white spot behind each eye and white belly. Some may have yellow or orange color on the borders of two primary colors. Fully adults ranges from a length of 16-26 feet (5-8 meters) and weigh between £ 5,500 and 16 000 (£ 2,495-7 257 kg). Men are generally somewhat larger than women.
The orcs are divided into a behavior -based ee. Orcas resident lives in matriarchal pods, with calves of both sexes remain permanently with mothers. The inhabitants only eat fish and often withThey find in the company of other dolphins, seals and sea lions. Studies have shown that when songs of resident murderous whales and sea lions are played, animals do not respond as predators. Orcas staying in entertainment parks are always inhabitants, because their diet is entirely based on fish.
Transient killer whales live in small groups, usually between two and six animals. They survive completely from other sea mammals and don't eat fish. Also, the transitions may not remain together in a permanent module. It differs from the inhabitants in terms of physical properties, including triangular and pointed dorsal flippers and a completely gray area of the saddle surrounding the back.
The third variety Killer Whale is called a whale at sea and has shown an elusive research subject for experts. It is believed that the coastal pods are genetically different from the population and transitions and have been seen traveling in groups of up to 60 animals. It is assumed thatThese orcs spend their entire lives by traveling, living on the diet of sharks and sea turtles.
Killer's whale has a comprehensive history of interaction with humans. Although there were only a few of the wild orc attacks on people, the species has long worried about coordinated hunting skills. The Latin name of the genus, orca , is reflected in English as "from hell", while the common name of the killer whale can also mean fear. Yet people have fascinated this giant dolphin for a long time and since 1964 they have kept the orcs in captivity.
Orca captivity is a controversial theme, and some experts believe that the tension of the tank life is damaging animals. 60-90% of the captured men of the orkolps of the dorsal fin xperience, which may indicate excessive stress on the animal. In the wild, the killer whales live 60-80 years, while in captivity most die at the age of 20-40 years. Wild orcs travel long distances in search of food and some experts suggest that tanks, although large, cannot compare with openThe space of their natural habitat. Proponents of captivity claim that allowing the public to interact with whales instill compassion for the species and can lead to an increased effort to maintain global preservation.
orcs exist in every ocean in the world, but are not protected from damage caused by pollution and environmental changes. Some of the Orc communities are considered to be endangered by experts, including the southern resident community from Washington and the British Columbia. Studies of this population have shown that their number has been reduced from 200 animals to 90 in a short time. The reasons for bankruptcy are considered to be pollution and a dramatical decline in the salmon population, the main source of food for the community. Whale Killer remains a fascinating predator of peak, but without the help of maintaining its natural ability and intelligence, it may not be enough to protect it from permanent damage to the population.
