Orca

Orca, porpoising to swim faster.

Orcas, or killer whales, are meat eaters. They commonly survive off of sea lions when in the wild, and fish when in captivity. They can be trained, but even with the best of training can backflip into old habits easily. A few trainers from SeaWorld have been killed by orcas.

Killer whales are very big. They can weigh up to 6 tonnes minimum, and their dorsal fin is as tall, if not taller, than a human. They are black and white, and from a distance are mistaken as Rosso's dolphins, or false killer whales. They have very large and sharp enamel covered teeth.

Female orcas mature at around age 15. They can then have babies. Gestation period is about a year-year1/2. Babies are fed milk until about one year old, and are then weened from it. Weening takes about one year to complete.
