Carcharhinus plumbeus is commonly known as the sandbar shark, which is a type of requiem shark that inhabits shallow coastal waters. This species has several synonyms including brown shark, thickskin shark, and mustelus plumbeus. The sandbar shark is an apex predator and plays an important role in the marine ecosystem. Its teeth are perfect for crushing hard-shelled prey, including crabs and lobsters. The sandbar shark is known for its large size, reaching up to 8 feet in length and weighing up to 300 pounds. Despite being a popular game fish, the species is currently listed as vulnerable due to overfishing and the destruction of its habitat.
