Chinese Giant Salamander

A large, heavily built aquatic salamander typically measuring 3–5 feet (91–152 cm) in length, with some individuals exceeding 6 feet (183 cm). Body is robust and flattened dorsoventrally, with a broad, depressed head and small eyes positioned laterally. Skin is wrinkled and loose, forming numerous folds along the body and limbs that increase surface area for respiration. Dorsal coloration is typically dark brown to grayish-brown, often mottled or blotched with lighter tan or olive tones. The body is marked with irregular darker blotches and patches that lack a consistent pattern. Ventral surface is lighter, ranging from cream to yellowish-tan, often with dark mottling. Limbs are short and stout with four toes on the forelimbs and five on the hind limbs. The tail is laterally compressed and serves as a primary propulsive organ. A prominent dorsal ridge or crest may be present along the tail in some individuals. Gill slits are present in larvae but are obliterated in adults, which rely primarily on cutaneous respiration through their highly folded skin; supplemental lung respiration also occurs. Inhabits fast-flowing, cool, well-oxygenated mountain streams and rivers, typically in rocky habitats with caves, crevices, and rocky shelters. Prefers clear water with temperatures between 10–25°C (50–77°F). Diet consists primarily of fish, crustaceans, aquatic insects, and other invertebrates, as well as smaller salamanders and other vertebrates. Hunting occurs primarily at night; individuals are mostly sedentary during the day within rocky refuges.
