In many fish, the pectoral fins aid in walking, especially in the lobe-like fins of some anglerfish and in the mudskipper (see also walking fish) Certain rays of the pectoral fins may be adapted into finger-like projections, such as in sea robins and flying gurnards; In skates and rays, the pectoral fins are used for propulsion (rajiform ...

A peculiar function of pectoral fins, highly developed in some fish, is the creation of the dynamic lifting force that assists some fish such as sharks in maintaining depth and also enables the "flight" for flying fish. Certain rays of the pectoral fins may be adapted into finger-like projections, such as in sea robins and flying gurnards.
Well developed fins are used for maintaining balance, braking and changing direction. The pectoral fins act as pivots around which the fish can turn rapidly and steer itself. The paired pectoral and pelvic fins control pitching, while the unpaired dorsal and anal fins reduce yawing and rolling. The caudal fin provides raw power for propelling ...
The ridge of their spine also has some darker coloration. A large black patch is apparent on the lower base of the pectoral fins. [5] The spines of their dorsal fin are yellowish gray and black towards the tip. [5] The dorsal fin on juvenile roosterfish is black with a white bar in the center and white, yellow, and black striping towards the top.
In modern fishes, the cleithrum is a large bone that extends upwards from the base of the pectoral fin and anchors to the cranium above the gills, forming the posterior edge of the gill chamber. [2] The bone has scientific use as a means to determine the age of fishes. The lobe-finned fishes share this arrangement.
The pectoral fins and tail fin are greyish while the other fins are colourless. Juvenile fish are sometimes barred with black. [3] This species can be distinguished from the oceanic two-wing flyingfish (Exocoetus obtusirostris) by having a less blunt snout and by the origin of the anal fin being at a location behind the origin of the dorsal fin ...
There are teeth on the sides of the roof of the mouth. There is a single, central spine on the preoperculum. The pectoral fins are wedge-shaped with 16–18, typically 17 rays, the longest rays being in the centre and the third to eighth rays are branched at their tips in adults. The dorsal fin has 12 spines and usually has XII, 10.5, rarely 9. ...
