Stealthy Tactics Used By Orca To Catch Their Prey
Scientists from the University of Cumbria’s Centre for Wildlife Conservation say that killer whales may use hearing to help locate prey. By applying observation tags to whales in Alaska, the team of researchers found that these mammals used a stealth approach to hunt other mammals. The whales, known for their clicking and echolocation abilities, go silent before a kill so as to go undetected. They eavesdrop on their prey, such as a male harbor seal calling to a potential mate, and then they strike. The team plans to do more research using pre-recorded seal roars and porpoise echolocation clicks.
