CONTENT PREVIEW

The blue whale is the largest animal ever known to have existed, reaching lengths of up to 100 feet and weighing as much as 200 tons. Despite its enormous size, this gentle giant feeds almost exclusively on tiny shrimp-like creatures called krill.
Blue whales are found in oceans worldwide, from the Arctic to the Antarctic. They migrate long distances to feed and breed, often traveling thousands of miles each year.
Unfortunately, blue whales are listed as an endangered species under the U.S. Marine Mammal Protection Act. They were nearly driven to extinction in the 20th century due to commercial whaling, which killed over 360,000 blue whales. Although whaling is now banned, blue whales still face threats from ship strikes, ocean noise pollution, and climate change, which affects their food supply.
Conservation efforts include tracking blue whale populations, creating protected marine areas, and reducing ship speeds in whale habitats. These measures have helped some populations recover, but the species remains at risk.
Fun fact: A blue whale’s heart is the size of a small car, and its tongue can weigh as much as an elephant!
