Aipysurus foliosquama

Aipysurus foliosquama, also known as the leaf-scaled sea snake, is a critically endangered species of venomous sea snake in the family Elapidae. It was formerly endemic to the Ashmore and Cartier Islands of Australia,[1] having thought to have become extinct there. In 2015, the snake was discovered in seagrass beds of Shark Bay off Western Australia.[2]

Taxonomy

The species was first described in 1926. The combination Smithohydrophis foliosquama (Kharin 1981) is recognised as a synonym.[1]

Description

The recorded length is around 800 millimetres and coloration is purple brown. A poorly known species, the diet is known to consist of wrasse and gudgeon fish that are pursued through coral outcrops and crevices.[3]

Distribution and habitat

The distribution range of the species has contracted since its first identification, and is currently known from a declining population inhabiting Shark Bay on the western coast of Australia.[1] The leaf-scaled sea snake prefers waters up to 10 metres in depth.[4]

In December 2015 a population of the snakes was found living in seagrass beds of Shark Bay off Western Australia.[2] Previously, its only known habitats were some 1,700 km away in the Ashmore and Hibernia Reefs in the Timor Sea,[1] from where it had since disappeared.[5]

Conservation status

The range of Aipysurus foliosquama has significantly decreased and population is significantly declining, the IUCN lists their status as critically endangered.[1]
