They have also been used for similar purposes by scientists studying whales. [ 2 ] Fluid dynamics researchers have proposed multiple mechanisms for the formation of flukeprints, including vortex shedding from the fluke of the whale, the action of surfactants on the surface of the water, and shear flow in the interaction between water waves and ...

Spinner dolphins generally have tripartite color patterns. The dorsal area is dark gray, the sides light gray, and the underside pale gray or white. [6] Also, a dark band runs from the eye to the flipper, bordered above by a thin, light line. However, the spinner dolphin has more geographic variation in form and coloration than other cetaceans.
[13] [14] The only known predator of the Pacific white-sided dolphin is the killer whale, [15] but at least one case of predation by the great white shark has been recorded. [16] The total population may be as many as 1 million. [6] However, the tendency of Pacific white-sided dolphins to approach boats complicates precise estimates via sampling.
The family Balaenidae, the right whales, contains two genera and four species. All right whales have no ventral grooves; a distinctive head shape with a strongly arched, narrow rostrum, bowed lower jaw; lower lips that enfold the sides and front of the rostrum; and long, narrow, elastic baleen plates (up to nine times longer than wide) with fine baleen fringes.

Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.
