Killer Whales Attack Gray Whale Calf

<p>This video shows a full predation event on a gray whale calf in Monterey Harbor, California. A group of seven killer whales chased and attacked a mother and a calf. The pursuit lasted over an hour and covered several miles near the shore in Monterey. The gray whale mother defended her calf fiercely but the killer whales were successful and the calf died hours later. Credit: YouTube/Monterey Bay Whale Watch</p>
