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, named for their bluish-gray coloration, are known for their immense size. Their coloration often includes grayish or whitish areas. When viewed from above, the rostrum appears broad and U-shaped and a large splashguard surrounds two blowholes. A blue whale's slender, vertical blow can reach a height of 9 m (30 ft.). Blue whales have 55-68 vertical grooves extending back almost to the navel. The dorsal fin is very small and set Â¾ of the way back and the trailing edge of the flukes are smooth except for a small notch in the center.
