Scientifically, the Orca is known asthe Orcinus orca. Although the nameKiller Whale suggests the opposite, they are not whales. Orcas are a part ofthe Delphinidae Family; they are a species of dolphin. These mammals arecarnivores, known for hunting in groups of approximately forty called podswhich are often noted as similar to wolf hunting packs. They eat seals,seabirds, fish, and even whales. They have more than forty teeth, each aboutten centimeters long to eat their prey. Orcas are the largest in the dolphinfamily and can grow anywhere from twenty-three to thirty-two feet long as wellas weight up to six tons. They can be found in various locations throughout theEarth from the arctic to equator, despite most media representation depictingthem in the wild to 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, weighing betweenfive and six kilograms. The Orca also has the ability to communicate with othermembers of its species through echolocation, similar to Beluga Whales who usethis skill to find food and other members of its species. These pods also seemto contain members of an extended family, and they have a matriarchal system,as the female Orcas are known to protect their offspring as well as othermembers of their pod.
Female Orcas have offspring every three to five years andgo through seventeen-month pregnancies (Britannicaand National Geographic).
