Ecology

Giant Crocodiles dominate tropical and subtropical swamps, rivers, and brackish estuaries. They are ambush predators eating fish, large mammals, dinosaurs, and humanoids alike. They can weigh over 5,000 pounds and exceed 20 feet in length. They reproduce by laying clutches of eggs in mud nests, fiercely guarded by mothers. Adults can live 80 years or more, growing larger throughout their lives.

Behaviour

Patient, ambush-driven, and astoundingly aggressive when prey is near, Giant Crocodiles strike from murky water without warning. They cache kills underwater in submerged dens, returning to feed days later. They tolerate other crocodiles only during mating season, otherwise hyper-territorial. They fear only larger predators (Hydra, Tyrannosaurus, river dragons) and sometimes flee these.

Origin

Surviving descendants of prehistoric crocodilians, Giant Crocodiles thrive in regions untouched by significant civilization. Some lizardfolk tribes worship them as avatars of Semuanya, the lizardfolk god of survival. Yuan-ti use them as guardians of jungle temples. A few have grown to legendary size and developed minor magical traits, becoming the foundation of stories about river-eating leviathans.
