Field Notes
A large, heavy-bodied crocodilian typically measuring 72–96 inches (183–244 cm) in total length, with some individuals approaching 110 inches (280 cm). Body is robust and relatively broad compared to crocodilians of similar size. Head is moderately broad with a U-shaped snout and relatively small eyes positioned high on the skull. Dorsal coloration is typically dark olive-green to blackish-gray, often with faint darker crossbands or reticulations most evident on juveniles and younger adults. Dorsal surface of the head and trunk is covered with well-developed, rectangular osteoderms (bony plates) arranged in regular longitudinal rows. Ventral surface is pale yellowish to whitish, often with dark mottling. Scales are relatively small and numerous compared to American Alligators. A key diagnostic feature is the presence of a prominent ridge or crest along the snout, located anterior to and above the eyes, and a more slender rostrum than American Alligators. Limbs are relatively short and stocky. The tail is laterally compressed and constitutes roughly half the total length. Primarily inhabits freshwater environments including slow-moving rivers, lakes, wetland marshes, and swamps in subtropical and warm temperate regions. More tolerant of cooler water temperatures than most other crocodilians and capable of surviving seasonal dry periods. Diet consists primarily of fish, crustaceans, and aquatic insects; larger individuals may consume waterfowl, small mammals, and other reptiles.
