Killer Whales

Common Name: Killer Whale

Scientific Name: Orcinus Orca

Habitat: Killer Whales are found in both the open ocean and coastal waters. Killer Whales inhabit all the oceans of the world. They are most numerous in the Arctic, the Antarctic, and areas of the cold-water up-welling  Killer whale distribution is limited by seasonal park ice.

Reproduction: Calves are born throughout the year. Gestation is about 17 months. Calves are born in the water. Deliveries can be either tail-first or headfirst. The umbilical cord snaps during or soon after delivery.

Status: The worldwide population of killer whales is unknown. Specific killer whale populations in a few areas have been estimated. In some area of the Antarctic alone, their numbers are estimated at about 180,000. Killer whales are not endangered.

Interesting Facts: 
-- Olfactory lobes of the brain and olfactory nerves are absent in all toothed killer whales, indicating that they have no sense of smell. 
-- Killer whales have 40 to 50 teeth that are up to four inches long.
-- Killer whales can weigh up to six tons, and grow to be 23 to 32 feet long.

Why I chose this animal: I chose the Killer Whale because it is a huge predator of the ocean. I find it to be a very interesting animal.
