Whale watchers were stunned last week to see 28 blue whales feeding on krill in Monterey Bay. Blue whales are the largest animal ever to live on earth and are also highly endangered with an estimated population of only 10,000 compared to over half a million a few decades ago. A second season of plentiful krill seems to have lured the whales in the bay. Whale watchers also saw a pod of 30-35 humpback whales feeding in the bay as well.
