The southern river terrapin is a large aquatic turtle with a smooth oval shell and strong webbed feet. Adults inhabit tidal rivers, estuaries and mangroves, feeding mainly on fruit and aquatic vegetation. Females migrate to sandy banks or beaches to lay eggs, while males develop conspicuous seasonal head and neck coloration (Wikipedia, general species account). It is Nationally Critically Endangered (Thailand Red Data 2025).
