Killer whales (orcas) use their teeth to catch prey. Killer whales eat a wide variety of food including other marine mammals, fish, sharks, birds, and turtles. 2. Killer whales use their tail (flukes) to propel themselves through the water. By rapidly moving the tail, they could gain enough momentum to jump. 3. Killer whales can feed individually, or work together to catch prey. The latter is very interesting to watch. Killer whales have been seen to feed coordinated to catch marine mammals and to corral fish into tight balls. Killer whales could either use echolocation (sonar) to find food, or look for it with their eyes, or even just listen for the food to make sounds. If the killer whale doesn't make sound, prey like marine mammals, wouldn't be able to tell as quickly that a killer whale was nearby. 4. I'm not sure I'd agree with the idea that killer whales would not attack people. There is a famous incident of a pilot whale that grabbed a lady by the thigh that was swimming with it. Killer whales and other dolphins are wild animals, and people need to remember that it can be dangerous to swim with them. In fact, in U.S. waters, it is against the law to swim with any type of marine mammal. There is also an incident of a trainer that was killed by a killer whale in captivity. For the most part, killer whales seem to be "tame" in captive situations, and work well with their trainers. Also, in the wild, many people in some locations will kayak with the whales swimming around them...quite safely. ______________________________ Reply Separator _________________________________ Subject: Orca whales Author: TIAC CUSTOMER <firstname.lastname@example.org> at ~smtp Date: 10/7/96 11:10 AM How do orcas eat how do orcas billed up the speed to jump.How do orcas attck their pray.why do orcas not attck pepole.
