Step-by-step explanation:
Carcharhinus plumbeus is the scientific name for the Sandbar Shark, which can be categorized with other cartilaginous fish with distinct characteristics. Sharks, including the Sandbar Shark, possess several distinctive features such as a specific number of gill slits and varying types of fins, helping to differentiate them from other species. The Sandbar Shark is known for its long snout, which is a characteristic feature of groundsharks. This species, like all sharks, reproduces using internal fertilization. In the case of the Sandbar Shark, the reproduction is ovoviviparous, where eggs develop inside the mother's body and the young are born alive, a trait shared with mackerel sharks.
