Siamese crocodile (Crocodylus siamensis) is a small to medium-sized freshwater crocodile native to Indonesia (Borneo and possibly Java), Brunei, East Malaysia, Laos, Cambodia, Burma, Thailand, and Vietnam. The species is critically endangered and already extirpated from many regions. Its other common names include: Siamese freshwater crocodile, Singapore small-grain, cocodrilo de Siam, crocodile du Siam, buaja, buaya kodok, chorakhe nam chuet, and soft-belly.
The Siamese crocodile is a medium-sized, freshwater crocodilian, with a relatively broad, smooth snout and an elevated, bony crest behind each eye. Overall, it is an olive-green colour, with some variation to dark-green. Young specimens measure 1.2–1.5 m (3.9–4.9 ft) and weigh 6–12 kg (13–26 lb), growing up to 2.1 m (6.9 ft) and a weight of 40–70 kg (88–154 lb) as an adult. The largest female specimens can measure 3.2 m (10 ft) and weight 150 kg (330 lb) Large male specimens can reach 4 m (13 ft) and 350 kg (770 lb) in weight. Most adults do not exceed 3 m (10 ft) in length, although hybrids in captivity can grow much larger.
The historic range of the Siamese crocodile included most of Southeast Asia. This species is now extinct in the wild or nearly extinct from most countries except Cambodia. Formerly it was found in Cambodia, Indonesia (Borneo and possibly Java), Laos, Malaysia, Thailand, Vietnam, Brunei, and Burma.
