Orcas, or killer whales, are the largest of the
dolphins and one of the world’s most
powerful predators.
• Weight: 22,000 pounds.• Length : 32 feet.• Appearance: Black on top
with white undersides and white patches near their eyes.• Life Span: Males typically
live about 30 years, but Females can live as long as 50-60 years.• Diet: Fish, squid, sea lions,
and other marine mammals.• Behavior: Highly social
animals; rely on underwaterSound for orientation, feeding, and communication.
Facts:
Communication:
• Killer whales produce 3 categories of sounds:
1.Clicks – navigation, objects in the surrounding environment, and for prey.
2.Whistles – social activities 3.Pulsed calls – vocalization
(squawks, screams, and squeaks)
Sexual Maturity:Sexual maturity of a female killer whale is
achieved when the wale reach lengths of 15-18
feet, and may give birth at any time. Calves are nursed for about 1 year
and may be weaned between 1 and 2 years
of age.
Killer whales are most abundant in colder waters, including Antarctica, Norway, and Alaska. Killer whales are found in all parts of the oceans and in most seas from the Arctic to the Antarctic.
Classification:• Resident orcas are lovable and live in large family-centered pods that tend to stay in one area. They are the star attraction at SeaWorld.• Transient orcas are often found in long-term stable social units They are quiet and very sneaky, not many scientists know much about these particular group.• Offshore orcas are similar to resident whales, but can be distinguished generally such as their fins, which seem to be rounded at the tip with multiple nicks on the trailing edge.
Taxonomy:• Kingdom: Animalia• Phylum: Chordata• Class: Mammalia• Order: Cetacea• Family: Delphinidae• Genus: Orcinus• Species: Orca
