Known as the orca, this toothed whale is a member of the oceanic dolphin family. It is distinguished from the other members of this family by its black and white patterned body. These whales are highly social and live in family groups called pods.
Males have larger appendages than females
Among the dolphin family, the killer whale is the largest species. It is easily identifiable by its size and striking coloration. It lives in the waters of the North Atlantic and North Pacific oceans. The killer whale's snout is blunt and its underparts are white. Its skull has a large set of teeth. Typically, the skull has 10-12 teeth per row.
Killer whales feed on marine mammals and fishes. They are also known to hunt octopus and sea birds. Their prey includes cetaceans, porpoises, and sea lions. They have a unique form of sexual play that involves nipping and nuzzling the genital area with their beak and mouth.
Orcas migrate from the Antarctic to subtropical waters off Uruguay and Brazil
During the Antarctic summer, some orcas migrate from the Antarctic to subtropical waters off Uruguay and Brazil. These whales migrate from the Antarctic Peninsula to the edge of the tropics in 42 days.
The Antarctic killer whale is the largest known subspecies, reaching a maximum length of 9.1 meters (30 ft). These whales spend the summer months feeding in coastal waters, and then migrate to warmer waters to exfoliate. They have a black and white coloration, including a large elliptical white patch on the side of their head, which is called an eye spot.
The orca has a unique dorsal fin. The male orca's dorsal fin is 1.8 meters long, while the female orca's dorsal fin measures 3.2 meters. The dorsal fin has a muscular flap which covers a blowhole. It also has a small beak with 10 to 13 conical teeth.
Orcas live in family groups called pods
Pods are family groups of orcas, consisting of one or more mothers and their offspring. These family groups are formed through social interaction. They communicate with each other through sounds. They have a strong sense of community, and their interactions with one another are often marked by co-ordination and trust.
Some pods may consist of only one male or two females, while others may contain up to 50 whales. Each pod has its own individual sounds. They are typically seen traveling together. Some pods may form temporary groups. These pods may leave to join a different pod, while others may stay together for their entire lives.
Orcas are highly social
Unlike most mammals, killer whales are highly social. Orcas are generally matriarchal, meaning they have a mother, a mate, and one or more babies. Females typically give birth to one baby per five years. However, orcas can have multiple breeding partners throughout their life.
Orcas are highly intelligent marine mammals. Their brains are the second largest of any oceanic mammal. Their insula is also an impressive part of their anatomy, involving both emotions and spatial memory.
Killer whales have a wide range of intelligence. They are generally known for their ability to make complex social hierarchies within pods, and are often described as manifestations of animal culture.
Orcas are kept in captivity and trained as performers
Keeping orcas in captivity and training them as performers has been the subject of intense scrutiny in recent years. The recent documentary Blackfish sparked a public outcry, and has led to calls to ban the practice.
Captivity is a cruel environment for orcas. In captivity, they are forced to breed, and they are trained to behave in ways that they would not in the wild. Moreover, they are confined in concrete tanks that do not simulate the environment of the wild. This is not only harmful for orcas, but it is also detrimental to the trainers.
Captivity also has been linked to injuries and death. Orcas in captivity often exhibit aggressive behavior, and trainers are often attacked.
Orcas are a powerful carnivore
Known as killer whales, these marine mammals are powerful carnivores. Their diet consists of many different kinds of prey including fish, seals, seabirds, dolphins, and squid. They are also known to attack other whales.
Orcas are large and powerful marine mammals, weighing between 5,400 and 22,000 pounds. They are known for their long dorsal fins and black-and-white colouring. They can be found in all of the major oceans.
Orcas are members of the Delphinidae family of oceanic dolphins. They live in family groups called pods. These groups can be composed of as many as forty whales. These groups employ a wide variety of hunting techniques. Often, they use echolocation to identify their prey. They also use wave formation to pull their prey into the water.
