The tail of a shark consists of the caudal peduncle and the caudal fin, which provide the main source of thrust for the shark. Most sharks have heterocercal caudal fins, meaning that the backbone extends into the (usually longer) upper lobe. The shape of the caudal fin reflects the shark's lifestyle, and can be broadly divided into five categories:
E. naucrates is a medium-sized fish which can grow up to 110 cm (43 in) length. [ 9 ] Its body is elongated and streamlined, and its lower jaw is clearly prognathic (it projects forward well beyond the upper jaw). [ 3 ] The jaws, vomer and tongue have villiform teeth. [ 3 ] The main distinctive feature to distinguish from other fishes is the ...
The caudal fin has a strong lateral keel and a crescent shape. Other common names include bone shark, elephant shark, sailfish, and sunfish. In Orkney, it is called hoe-mother (contracted homer), meaning "the mother of the picked dogfish". [5] The basking shark is a cosmopolitan migratory species found in
The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. It is absent in many fish families, but found in nine of the 31 euteleostean orders ( Percopsiformes , Myctophiformes , Aulopiformes , Stomiiformes , Salmoniformes , Osmeriformes , Characiformes , Siluriformes and Argentiniformes ...
The dorsal fins also give the shark advantages. The first dorsal fin helps the spiny dogfish maintain a stable body position while swimming while the second aids in generating thrust. [18] The caudal fin is larger than normal, which helps the sharks maneuver through the water quickly and efficiently. [19]
A second, shorter pair of keels are present below the main keels. The caudal fin is large and crescent-shaped, with the lower lobe almost as long as the upper; both dorsal and ventral depressions (precaudal pits) are at the caudal fin base, and a deep ventral notch is near the tip of the upper caudal fin lobe.
