Carcharhinus plumbeus is a species of shark commonly known as the sandbar shark. It belongs to the family Carcharhinidae and is characterized by its robust body, broad and high dorsal fin, and large pectoral fins. The scientific name "Carcharhinus plumbeus" is derived from the Greek words "karcharos" meaning sharp, and "rhinos" meaning nose, referring to its sharp and pointed snout.
The sandbar shark has a gray to brownish-gray coloration on its upper body, fading to white on the underbelly. It typically grows to lengths of about 6-8 feet (1.8-2.4 meters) and has a maximum recorded size of around 10 feet (3 meters). Known for its gentle disposition, the sandbar shark inhabits primarily coastal and shelf waters in tropical and subtropical regions worldwide.
This species is an opportunistic feeder, preying on a variety of fish, cephalopods, and crustaceans. It uses its highly developed senses, including a keen sense of smell and hearing, to locate and capture its prey. Additionally, the sandbar shark is viviparous, giving birth to live young after an internal gestation period of approximately one year.
Although the sandbar shark is not listed as endangered, its populations have faced declines due to overfishing, both as a targeted species and as bycatch. This shark is a valuable resource for commercial and recreational fisheries, valued for its meat, liver oil, and fins. Conservation efforts, such as catch limits and protected marine areas, aim to ensure the continued survival and sustainability of Carcharhinus plumbeus populations.
