Orca

Orcas and Killer whales are found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas.
==Diet==
Killer whales as a species have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as sea lions and seals.
==Range and Habitat==
Killer whales are found in all oceans and most seas. Due to their enormous range, numbers, and density, distributional estimates are difficult to compare, but they clearly prefer higher latitudes and coastal areas over pelagic environments.
==Life Cycle==
Female killer whales mature at around age 15. They then have periods of polyestrous cycling with noncycling periods of between three and 16 months. Gestation varies from 15 to 18 months. Mothers calve, with usually a single offspring, about once every five years.
Females breed until age 40, meaning on average they raise five offspring. The lifespans of wild females average 50 years, with a maximum of 80–90 years. Males sexually mature at the age of 15, but do not typically reproduce until age 21. Wild males live around 29 years on average, with a maximum of 50–60 years.
