The great white shark is arguably the world's largest-known extant macropredatory fish, and is one of the primary predators of marine mammals, such as pinnipeds and dolphins. The great white shark is also known to prey upon a variety of other animals, including fish, other sharks, and seabirds. It has only one recorded natural predator, the orca.
An Atlantic white-sided dolphin off the coast of Cape Ann, Massachusetts. The Atlantic white-sided dolphin is built slightly 'thicker' compared to other oceanic dolphins; they are nearly indistinguishable from the Pacific white-sided dolphin, despite the fact that they are only very distantly related phylogenetically.

Commerson's dolphins in the Strait of Magellan. The commersonii subspecies has a black head, dorsal fin, and fluke, with a white throat and body. The demarcation between the two colours is very clear-cut. This stocky creature is one of the smallest of all cetaceans, growing to around 1.5 m (5 ft).
In 1986, the first vector-based clip art disc was released by Composite, a small desktop publishing company based in Eureka, California. The black-and-white art was painstakingly created by Rick Siegfried with MacDraw, sometimes using hundreds of simple objects combined to create complex images. It was released on a single-sided floppy disc.
In the 1990s, the sharks of the species from the same area averaged only 56.1 kg (124 lb). [11] The species is grey-bronze dorsally and white ventrally. [6] As its name suggests, most of its fins (dorsal, pectoral, pelvic and caudal) have white tips. Along with white tips, the fins may be mottled, and young specimens can have black marks.
The dusky dolphin has a distinctive colouration that resembles the Pacific white-sided dolphin. It has a dark grey or black upper area, light grey face, chest area, and flank patch, and a white underside. The flank patch has a branch that extends over the back and can reach the blowhole.
Dolphins live along the Myrtle Beach, S.C. coast year round. Learn about the habits of these residents and how to spot the locals.
In southern right whale dolphins (Lissodelphis peronii), the white patch extends higher on the posterior flanks and head. Calves, which are born initially creamy-dark grey or brown, attain adult colouring by the age of one year. [7] The beak of northern right whale dolphins is short and well-defined, characterised by a straight mouthline.
