Beluga Whales can swim backwards just as well as they swim forwards. Its head is rounded, and it has a short beak and a prominent, protruding forehead called the "melon". They have one blowhole. Beluga whales, aka white whales, Delphinapterus leucas (Pallas, 1776), are incredibly fascinating small whales with a characteristic stocky frame, solid white color, and bulbous melon. These sounds may function in communication. A dorsal ridge, more prominent in males, replaces the dorsal fin found in other whale species. In the case of whales, echolocation is an important means of finding their way, tracking and seizing prey, and perceiving threats in the water around them. Belugas have been hunted for centuries by native whalers for food, oil and "porpoise leather". The head (Melon) The melon is part of the nasal apparatus and made up mostly of tissue between the blowhole and the tip of the snout. In one echolocation study, a single beluga produced signals with peak frequencies of 40 to 60 kHz in San Diego Bay, California, and 100 to 120 kHz when moved to Kaneohe Bay, Hawaii. TO TOP, RETURN The Voice of the Beluga Whale (0:25 min) Beluga whales are known as the "canaries of the sea". Research on echolocation is ongoing. J Acoust Soc Am. The term echolocation refers to an ability that toothed whales (and some other marine mammals and most bats) possess that enables them to locate and discriminate objects by listening for echoes. Back to top Conservation. Scientists believe that the melon plays a part in the beluga's echolocation system. Unlike most other whales, the beluga has a very flexible neck that enables it to nod and turn its head in all directions. There is no evidence that beluga whales, or any other whales, use anything resembling human language. 2.

What happens when sound pressures are large? The beluga whale is referred to as a sea canary, because of its high-pitched song.
