The dusky shark (Carcharhinus obscurus) is a species of requiem shark, in the family Carcharhinidae, occurring in tropical and warm-temperate continental seas worldwide.

Dusky sharks are a requiem shark known for their slow growth rate, taking around 20 years to reach adulthood. They are also known for their seasonal migrations, for which they form temporary schools, disbanding and becoming solitary once they reach their destination.

Dusky sharks are big ocean predators that can reach up to 400 lbs. They are found in tropical and subtropical waters around the world and make long seasonal migrations all the way from the equator to the poles.

The shark is found on continental and insular shelves and oceanic water adjacent to them. It ranges from the surf zone to far out to sea, and from the surface down to 1312 ft [400 m]. DISTRIBUTION Cosmopolitan in warm temperate and tropical seas. BIOLOGY . Prey – Small sharks feed on bottom dwelling animals.

Carcharhinus obscurus Dusky sharks are wide-ranging coastal and pelagic species that prefer temperate to tropical waters. They are large-bodied, typically grey with dusky margins on the fins. They are an important fisheries resource, targeted and taken as bycatch around the world.

Dusky sharks, also known as bronze or black whalers, are long-distance swimmers known for seasonal, temperature-driven migrations that males and females undertake in separate groups.

In this section, we will discuss the physical characteristics, habitat and range, diet, and behavior of dusky sharks. Dusky sharks have a streamlined body with a rounded snout and sickle-shaped pectoral fins. They have a caudal fin with a long upper lobe and a shorter lower lobe.

The rounded snout is shorter or equal to the width of the mouth. The first dorsal fin originates over or near the free rear tips of the pectoral fins. The color is bronzy gray to blue gray

The dusky shark (Carcharhinus obscurus) is a species of requiem shark, in the family Carcharhinidae, occurring in tropical and warm-temperate continental seas worldwide. A generalist apex predator, the dusky shark can be found from the coast to the outer continental shelf and adjacent pelagic waters, and has been recorded from a depth of 400 m ...
