The scientific name is Orcinus Orca · The Orca was nicknamed the "Killer Whale" when it was seen eating another whale. It was originally called "Killer Whale" and was later changed to "Killer Whale". There are no confirmed records of orcas killing a human. Orcas are estimated to live 50-60 years. They are said to be capable of reaching an impressive speed of 34 miles per hour and covering 60-100 miles of ocean in per day. · Orcas have 48 sharp, conical-shaped, three-inch-long teeth and are known to eat low-flying birds and attack whales that are five times their size. They also like squid, herring, and some warm-blooded mammals consume about 100 pounds of fish a day, and their favorite food is salmon. The way they attack prey is by circling it. · The killer whale is black on the upper half of its body and white on the lower half because it is dark. their backs blend into the darker water and their white bellies blend into the sunlit water above them. · Male orcas can grow up to 32 feet tall, weigh more than eight tons, and have a dorsal fin up to five feet tall · Females can grow up to 22 feet tall, weigh about four tons, and have a dorsal fin of three feet. · Orcas are found in all of the world's oceans and prefer temperate or cool coastal waters. However, they also extend into polar areas. Some orca populations remain local and travel along predictable routes while others are transient and move large distances. · Mating and birth occur primarily in autumn and winter. Gestation lasts over 12 months, and at birth orcas are approximately 6-7 feet long and weigh nearly 400 pounds. They are born with tails first. Females can give birth to four to six calves in their lifetime. Orcas are very social whales and most pods consist of 5-30 individuals. Studies have shown that each pod has its own distinctive dialect or accent, and that members of the same pod can recognize each other through this distinctive dialect. Orcas do not migrate, but have seasonal movements, which are linked to the movement of prey and environmental changes. Capture of orcas for display has become controversial and more limited.
