Also known as brown shark, bronze whaler, common whaler, shovelnose, bay shark, and river whaler, the Dusky Shark is an endangered species of requiem sharks.
The most distinct feature of dusky sharks is their round snouts. They have slender bodies and long sickle-shaped pectoral fins. Their first dorsal fins have slopes. They possess interdorsal ridges on their backs. Their color is usually blue-gray to dark-gray on the dorsal side and white on the ventral side. The Dusky Sharks have triangular saw-edged upper teeth.
Dusty Sharks have a wide variety of choices for their diet. They particularly love cephalopods, bony fishes (like bluefish), rays, and fellow sharks. They also feast on sea turtles, crustaceans, marine mammals, and even carrion and garbage. Also part of the Dusky Sharks’ favorites is the pelagic fishes like tuna, mackerel, herring, anchovies, and flying fish, among others.
Dusty Sharks can grow up to 14 feet or 148 inches and weigh up to 765 pounds. This requiem shark is one of the largest in its family. Female Dusky Sharks are generally larger than the males; the former can measure up to 11.8 feet while the latter, 11.1 feet.
