Carcharhinus Obscurus, commonly known as the Dusky shark, is a species of large, predatory shark found in various oceanic regions around the world. It is a member of the Carcharhinidae family, which includes many other species of requiem sharks.
The Dusky shark typically grows to a length of about 3 to 4 meters (10 to 13 feet) and can weigh up to 500 kilograms (1,100 pounds). It has a slender body with a long, rounded snout and broad, triangular teeth designed for capturing and cutting through prey. Its coloration varies from a deep gray or brown to a bluish-black, often exhibiting a pale underside.
This shark species is known for its migratory behavior, often traveling long distances in search of food and warmer waters. They inhabit a variety of marine ecosystems, including coastal and offshore regions, and can be found at depths ranging from near the surface to over 400 meters (1,300 feet).
As an apex predator, the Dusky shark feeds primarily on bony fish, small sharks, rays, and occasionally cephalopods. It employs both stealth and speed to capture its prey, usually launching swift attacks from below. While generally considered non-aggressive towards humans, Dusky sharks have been known to exhibit aggressive behavior when provoked or threatened.
Due to overfishing and habitat degradation, the Dusky shark population has declined significantly in recent years. Consequently, several countries have implemented conservation measures to protect this species and monitor its population. The International Union for Conservation of Nature (IUCN) classifies the Dusky shark as a vulnerable species, highlighting the need to address the threats it faces in order to ensure its long-term survival.
