Location Habitat

These sharks love the warm, tropical waters all over the world. They are the most common sharks of the “Pelagic Zone” which are continental shelves with depths of 500 meters or more (1,640ft). But often times, they are seen near the surface as well. The desired water temperature is 20 to 30 degrees Celsius (60 to 86 degrees Fahrenheit). Found abundantly near the edge of continental and insular shelves, but also in the open sea and occasionally inshore. Often found in deepwater reefs and near insular slopes. Littoral and epipelagic, in the open sea or near the bottom at 18-500 m. It is quick-moving and aggressive. Solitary; often associated with schools of tuna. Feeds mainly on fishes, but also squid, paper nautiluses, and pelagic crabs. Viviparous. Regarded as dangerous to humans. Flesh utilized fresh and dried-salted for human consumption; its hide for leather; its fin for shark-fin soup; its liver for oil. 2 to 14 young, 73 to 87 cm, are born per litter

Biology & Physical Description

Gray to brown above, white below. Skin looks and feels silky. Dorsal is comparatively small and begins at a point behind the pectoral fin. Most are a Bluish gray, large slender shark, the Silky is characterized by a moderately extended, rounded snout, a relatively sloping first dorsal fin with a blunt apex that originates behind the free margins of the pectoral fins, a small second dorsal fin with an extremely long free rear tip (more than 2x the height), and a low inter-dorsal ridge. Pectoral fins are long and slender, typically with dusky tips. The Silky Shark, also known as the Carcharhinus Falciformis, gets its name from the smooth and silky texture of its skin. Depending on its geographical location, it is also known as the Grey Reef Shark, Olive, Whaler, and sometimes Blackspot. These sharks have a streamlined and slim body. As adults, they can reach 3.5 meters (12ft) in length and weigh around 350 kilograms (770 pounds). They have an extremely strong sense of hearing. This acts as a great advantage for locating their preys, mostly consisting of bony fish (especially Tuna), octopuses, and squids. These predators have a perfect and effective hunting behavior. They dive together in large groups of fish and attack them with lighting fast speed and wide open mouths. Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A large, slim shark with a moderately long, flat and rounded snout, large eyes, small jaws, and oblique-cusped teeth with serrations; 2nd dorsal fin low and with greatly elongated rear tip. Grey or bluish-grey above, white below; no conspicuous fin markings. Only Carcharhinus species with an interdorsal ridge that has the dorsal fin origin behind the free rear tip of the pectoral fin

Life Cycle & Mating Behavior

Viviparous, placental. 2-15 pups born at 57-87 cm TL; 1-16 pups born at 55-72 cm TL. Females appear to breed every year, but there appears to be no reproductive seasonality (Ref.58048). Distinct pairing with embrace

Tackle & Baits

Can often be sighted and - if the angler wishes - baited in clear offshore waters. Baits cut from fresh-dead fish, such as Bonito, are best.
