Crocodiles and Alligators in Thailand: Species Guide

Thailand is home to crocodiles—but no native alligators. The "alligators" sometimes referenced are actually misidentified crocodiles or the critically endangered Chinese alligator (not wild in Thailand).

Native Crocodile Species

1. Saltwater Crocodile (Crocodylus porosus)

• Status: Rare/extirpated in the wild; historically coastal
• Habitat: Estuaries, mangroves, lower rivers, coastal seas
• Range: Andaman Sea coast (Phang Nga, Krabi, Phuket), Gulf of Thailand historically
• Size: World's largest reptile; males 5–6+ m (16–20+ ft)
• Current: Mostly in farms; wild sightings extremely rare

2. Siamese Crocodile (Crocodylus siamensis)

• Status: Critically Endangered (IUCN); functionally extinct in wild
• Habitat: Freshwater rivers, lakes, marshes, swamps
• Historical range: Chao Phraya, Mekong basins, central/eastern plains
• Size: Medium; 2–3 m (6–10 ft)
• Conservation: Captive breeding/reintroduction programs (e.g., Kaeng Krachan, Pang Sida)

Crocodile Farms

Thailand has a massive crocodile farming industry (70,000+ animals, mostly C. porosus × C. siamensis hybrids) for skins and meat. Major farms: Samut Prakan (Crocodile Farm & Zoo), Sriracha, Chonburi. Tourist shows feature "wrestling"—controversial for welfare.

Alligators?

No wild alligators in Thailand. The Chinese alligator (Alligator sinensis) is native only to the lower Yangtze (China). Any "alligator" in Thailand is a misidentification or escaped pet.

Safety

Wild crocodile encounters are vanishingly rare. In farm/zoo settings, follow all barriers and guide instructions. Never approach water's edge in known crocodile habitat at night.
