Crocodylus acutus, known as the American crocodile, is a large, carnivorous reptile found in coastal areas, brackish waters, and river mouths of the Americas. It is notable for its V-shaped snout, gray-green coloration, and ability to thrive in both freshwater and saltwater environments. This species plays a crucial role as an apex predator, maintaining the balance of its ecosystem.

Crocodylus acutus, commonly known as the American crocodile, is primarily found in the Neotropical region. Its geographical distribution includes the coastal areas of southern Florida, Mexico, Central America (including Belize, Guatemala, Honduras, Nicaragua, Costa Rica, and Panama), the Caribbean islands (such as Cuba, Jamaica, and Hispaniola), and the northern part of South America, particularly along the coasts of Colombia, Venezuela, and Ecuador.

The American crocodile inhabits a variety of coastal and estuarine environments. It is typically found in brackish and saltwater habitats such as mangrove swamps, lagoons, rivers, and coastal marshes. The species prefers warm, tropical climates with temperatures typically ranging from 25 to 35°C (77 to 95°F).

Crocodylus acutus is an apex predator and plays a crucial role in its ecosystem by maintaining the balance of aquatic and terrestrial environments. It preys on a wide range of species, including fish, birds, mammals, and occasionally carrion. The species is adapted to both freshwater and saltwater environments, with physiological adaptations that allow it to excrete excess salt. Juveniles tend to occupy freshwater habitats more frequently than adults, which can thrive in saltwater conditions.
