The beluga whale (also known as the ... be seen communicating with one another using a series of high pitched clicks and whistles and like other toothed whales the beluga whale uses echolocation to search for food and navigate the ocean. CrossRef Google Scholar 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. The sound waves produced by a beluga whale bounce off objects in the water and return to the beluga in the form of an echo. 60 (Suppl. Most dives range between 9-18 minutes.

They accomplish this by emitting highly directional, short (<200 μs), broadband clicks in rapid trains. The maximum observed swim speed of a beluga whale is about 17 mph (27.5 km/h) for short distances. (An order is a large group of related animals.) An experiment compared the echolocation abilities of a beluga whale and a bottlenose dolphin to detect five targets of the same size and target strength ( + / − 2 dB) at distances from 40 to 120 m. The performance for both animals at 40, 60, 80, and 100 m exceeded 90% correct detection; however, performance at 120 m ranged between 60% to 62% correct detection. The beluga whale is a toothed whale and like dolphins they use echolocation to find prey, communicating and navigating. Introduction . Whales use echolocation mainly for navigation and hunting. Each lobe of the tail is called a fluke.

Gurevich, V. S. and W. E. Evans 1976 Echolocation discrimination of complex planar targets by the beluga whale (Delphinapterus leucas). The echolocation faculty of odontocete cetaceans allows them to probe the aquatic environment with higher acuity than any existing man-made sonar systems .

The bump on a beluga whale’s forehead houses the ‘melon’, an organ used in echolocation. This adaptation is helpful in an environment where sea ice can change rapidly. Feeding dives last 18-20 minutes, rarely lasting longer. Echolocation. Echolocation provides whales a way to gather information about objects and prey around them including their range and configuration. The beluga whale can swim backwards. Acoust. The beluga, like these orcas, is a ‘toothed whale’. Why is echolocation helpful? A deep median notch separates the two flukes. The orca is a predator of the beluga whale. Jour. Dives/Depths.
Beluga whales, like all whales, are marine mammals in the order Cetacea. How sensitive is echolocation? Keywords: echolocation, beluga, click, double pulse, sound production, phonic lips.
The sound bounces back from objects in the form or echoes.

Flukes. Soc. 1)S5–S6.

Beluga whales produce clicks with their mouth which pass through the echolocation organ, the melon.

1. Note: The cetacean species is comprised whales, dolphins and porpoises. Physical Characteristics and Appearance. The beluga whale and … Beluga whales use their pectoral flippers mainly to steer and, with the help of the flukes, to stop. The flukes of beluga whales are distinctly curved along the trailing edges. The cetacean environment is often dark and hard to see in.

Flukes are flattened pads of tough, dense, fibrous connective tissue - completely without bone.
