Inthe scientific world, the Orca is known taxonomically as the Orcinus orca. Although the name KillerWhale suggests the opposite, they are not whales.
Orcas are a part of theDelphinidae Family; they are a species of dolphin. These mammals are carnivores,known for hunting in groups of approximately forty called pods which are oftennoted as similar to wolf hunting packs. They eat seals, seabirds, fish, andeven whales. They have more than forty teeth, each about ten centimeters longin order to eat prey. These animals are the largest in the dolphin family and cangrow anywhere from twenty-three to thirty-two feet long as well as weight up tosix tons. They can be found in various locations throughout the Earth from thearctic to equator, despite most media representation depicting them in the wildto live in only arctic waters.
Orcas are also considered quiteintelligent, which is one reason why they are often trained in captivity toperform tricks. They have the largest brains out of all dolphins, weighingbetween five and six kilograms. The Orca also has the ability to communicatewith other members of its species through echolocation, similar to BelugaWhales who use this skill to find food and other members of its species.
Thesepods also seem to contain members of an extended family, and they have amatriarchal system, as the female Orcas are known to protect their offspring aswell as other members of their pod. Female Orcas have offspring every three tofive years and go through seventeen-month pregnancies (Britannica and NationalGeographic).
