Acrochordus granulatus is the smallest of the three members of the family Acrochordidae, and is commonly called the "little file snake". Acrochordus granulatus is also the only Acrochord that permanently inhabits estuaries as well as coastal seas, dawning its other common name the "marine file snake". All members of Acrochordus are completely aquatic and nearly helpless on land. As with the other members of the genus, Acrochordus granulatus has uniquely spinose scales with an almost rough texture. Members of Acrochordus also possess specialized tubercles with nerve endings on the skin between their scales which provide an extra sensory organ used to feel water movements of prey. Acrochordus granulatus also have laterally compressed tails, and they can flatten dorsoventrally to assist in swimming. Acrochordus granulatus are the most marine of the Acrochordidae and have specialized sublingual salt glands similar to those found in the true sea snake subfamily Hydrophiinae. Despite this, they are still susceptible to dehydration at sea and rely on freshwater lenses built up on the surface of marine water for freshwater. Members of the true sea snake subfamily Hydrophiinae have been shown to exhibit this same behavior. Acrochordus granulatus are sexually divergent, with females being slightly larger than males.
