These impressive warm-blooded mammals of the deep have inhabited the earth mighty oceans for millions of years. Known as the world’s largest animal, can you believe that the Blue whale has a heart that weighs around 1,000 pounds? Twice as large as the largest known dinosaur, this 94 ft. long gentle giant feeds on one of the smallest creatures krill (shrimp-like crustaceans). Blue whales weigh up to 200 tons and can be found in all the world’s oceans, from the icy polar seas to the warm tropics. There is little known about how these magnificent animals travel, breed and communicate. The vocalizations (sounds) of whales may sound like they are singing, but whales are actually using echolocation to communicate and hunt.
Though blue whales may be the largest species, they certainly aren’t the only one. Other common whales include the Write Whale, Sperm Whale, Humpback and the smallest whale, the Beluga.
There are approximately 78 species of whales, dolphins, and porpoises, all related and are protected by the Marine Mammal Protection Act (MMPA). Did you know the killer whale is actually a dolphin and not a whale?
Global changes and pollution threaten the survival of these magnificent animals. Take time to find out what you can do today to help cherish these wondrous whales and ensure their survival for future generations.
