The shape, size, position and colour of the dorsal fin varies with the type of billfish, and can be a simple way to identify a billfish species. For example, the white marlin has a dorsal fin with a curved front edge and is covered with black spots. [4] The huge dorsal fin, or sail, of the sailfish is kept retracted most of the time. Sailfish ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races, [1] subspecies, or possibly even species [2] (see species problem).
The dorsal fin of a northern bottlenose whale in Newfoundland with a large linear scar visible. Distinct markings are used to identify unique individual whales and estimate their population size. When physically mature, northern bottlenose whales can reach 9.8 metres (32 ft) in length, [ 5 ] smaller than giant beaked whales , and larger than ...
The dorsal fin is sickle-shaped; and flippers are narrow, short, and pointed, with a distinctive bulge on the leading edge of the flipper (the side closest to the head). False killer whales are large marine predators. They are the fourth-largest extant species of oceanic dolphin, exceeded in size only by the orca, and the two species of pilot ...
Pilot whales are mostly dark grey, brown, or black, but have some light areas such as a grey saddle patch behind the dorsal fin. [4] Other light areas are an anchor-shaped patch under the chin, a faint blaze marking behind the eye, a large marking on the belly, and a genital patch. [4] The dorsal fin is set forward on the back and sweeps backwards.
A female killer whale surfaces, showing its dorsal fin and saddle patch. See also: Wildlife photo-identification In the early 1970s, Bigg and his colleagues discovered that individual killer whales can be identified from a good photograph of the animal's dorsal fin and saddle patch taken when it surfaces.
The chin, throat and belly are creamy white. The beak, flippers, back, and dorsal fin are a dark gray. Light gray patches are seen on the sides and a further light gray stripe runs from above the eye to below the dorsal fin, where it thickens along the tail stock. A dark gray ring surrounds the eyes. The species is an average-sized oceanic dolphin.
