Elusive Whales Set New Record for Depth and Length of Dives Among Mammals. A new study of elusive Cuvier's beaked whales shows they can dive to nearly 10,000 feet (3,000 meters). View Images. A Cuvier's beaked whale swims just under the surface of the ocean near the GalÃ¡pagos Islands.
Blue whales are rorqual whales, whales that have pleated throat grooves that allow their throat to expand during the huge intake of water during filter feeding. Blue whales have 50-70 throat grooves that run from the throat to mid-body. SIZE Blue whales grow to be about 80 feet (25 m) long on average, weighing about 120 tons (109 tonnes). The largest specimen found was a female 94 feet (29 m) long weighing more 174 tons (158 tonnes). The females are larger than males, as with all baleen whales.
