From there, the click is shipped ahead, through the junk, and amplified out into the watery world. Sperm whales may be able to manipulate the shape of both the spermaceti organ and the junk, presumably allowing them to aim their clicks.
Benoit-Bird figured out that the strains were columns of tiny bubbles the murres expelled when their feathers compressed as they dove. The nonfictional relationship between sperm whales and squid is pretty fling reviews dramatic also. A single sperm whale can eat more than one ton of squid per day.
