Secret Killers of Monterey Bay
建議用ie瀏覽器 Secret Killers of Monterey Bay California’s Monterey Bay has a huge variety of sea life, from tiny shrimp to giant humpback whales. All this life draws the ocean’s top hunters—killer whales. Killer whales are actually a kind of large dolphin. Like their smaller gray cousins, black-and-white killer whales are smart and social. They live in families that are called pods, and they are known for being silent and sneaky killers. Not even sharks will go up against killer whales. What they eat depends on what kind of killer whale they are. Resident killer whales stay in one area and usually eat fish. Other pods cover thousands of miles of ocean in one year. These transient killer whales hunt sea lions and baby gray whales. While killer whales hunt fish and sea lions, there is a secret killer that pursues the hunters. Scientists have discovered dangerous levels of toxins in killer whales. This is because of ocean pollution, and it is causing fewer of these great animals to be spotted every year. Unless steps are taken now to clean up the oceans, killer whales may vanish forever.
