Carcharhinus falciformis, commonly known as the silky shark, is known for its sleek, smooth appearance and long pectoral fins. Found in warm tropical oceans, it is highly migratory and often seen near reefs and in open water. This species is a swift and opportunistic predator, feeding on fish and cephalopods.

Carcharhinus falciformis, commonly known as the silky shark, is found in tropical and warm temperate seas worldwide. Its geographical distribution includes the Atlantic, Pacific, and Indian Oceans. In the Atlantic, it ranges from the coastal waters of Massachusetts in the United States to southern Brazil, including the Gulf of Mexico and the Caribbean Sea. In the Pacific, it is found from southern California to Peru, and across the central and western Pacific islands. In the Indian Ocean, it occurs from the Red Sea and East Africa to India, Southeast Asia, and northern Australia.

The silky shark inhabits pelagic waters, often found in open ocean environments but also near continental and insular shelves. It prefers warm waters with temperatures generally above 23°C (73°F). This species is often associated with deep water, typically between 200 to 500 meters, but can also be found near the surface, especially around oceanic islands and offshore platforms.

Silky sharks are apex predators in their habitat, preying on a variety of fishes, cephalopods, and crustaceans. They are known to follow tuna schools, as they share similar prey. The silky shark plays a significant role in maintaining the balance of marine ecosystems by controlling the population of mid-level predatory fish and cephalopods.
