American Crocodile (Crocodylus acutus) lives in brackish coastal waters across Neotropics. It feeds on fish and crustaceans. Its conservation status is Vulnerable.
Fascinating facts about the American Crocodile
- The American crocodile is the only crocodile besides the saltwater species that regularly lives and thrives in true saltwater. It tolerates high salinity thanks to specialised salt glands beneath the tongue, allowing it to occupy coastal zones rather than freshwater rivers. Consequently it is often seen on beaches and tiny islands that lack any fresh water, such as the many Caribbean cays and islets.
- American crocodiles are capable of inhabiting hypersaline lakes, a rarity among large reptiles. One of the biggest known groups lives in Lago Enriquillo, a hypersaline lake in the Dominican Republic, representing the largest Caribbean population. This lake supports a dense crocodile community despite its extreme salinity, illustrating the species' remarkable salt tolerance.
- A specimen measuring 3.2 metres and weighing 164 kilograms was recorded biting with a force of 4 355 newtons, demonstrating the immense power of its jaws. This bite strength is comparable to the force generated by large industrial presses, underscoring the crocodile's capability to crush prey. The animal's elongated snout houses a strong pair of jaws, a feature typical of the species and linked to its status as one of the largest crocodilians.
- American crocodiles coexist with the American alligator in Florida, where the two predators share the same wetlands. They also share habitats with the smaller spectacled caiman in Central America and South America.
- The American crocodile has the most reduced dorsal osteoderms amongst all living crocodilians. Its back therefore bears a smoother line of bony plates than any other extant crocodile.

About the American Crocodile
In the murky waters of the Caribbean coast, a relic of a bygone era glides effortlessly, its scaly body undulating as it navigates the tangled mangrove roots with a stealth that belies its formidable power. The American Crocodile, a creature of ancient lineage, moves with a deliberate slowness, its eyes and nostrils poking above the surface like a primordial sentinel, ever vigilant for the next unsuspecting meal. As it disappears into the shadows, its tail swishing gently behind, we are reminded of the enduring majesty of this vulnerable giant, a testament to the enduring power of a species that has survived for millennia.
