Carcharhinus acronotus, commonly known as the blacknose shark, is a small, coastal species found in warm Atlantic waters. It features a distinct dark spot on its snout, slender body, and pale coloration. Blacknose sharks are social, often forming groups and feeding on small fish and invertebrates.

Carcharhinus acronotus, commonly known as the Blacknose Shark, is native to the western Atlantic Ocean. Its geographical distribution extends from North Carolina in the United States down to southern Brazil, including the Gulf of Mexico and the Caribbean Sea.

The Blacknose Shark typically inhabits warm, shallow coastal waters. It is often found in areas with sandy or muddy substrates and prefers water temperatures ranging from 20 to 30 degrees Celsius (68 to 86 degrees Fahrenheit). These sharks are usually found at depths of 5 to 30 meters (16 to 98 feet), although they can occasionally be encountered at greater depths.

Carcharhinus acronotus occupies a niche as a mid-level predator in its marine environment. It primarily preys on small bony fish and cephalopods, contributing to the regulation of prey populations. The species is well adapted to its habitat, with a streamlined body that is effective for agile swimming and quick bursts of speed necessary for capturing prey in coastal and open ocean environments.
