Details

  • The newly discovered eel belongs to the Congrid eels group and has been named Ariosoma indicum.
  • The term Indicum means that it was found in India.
  • The total length of the new species is 362 millimetres.

 

Features

The eel has the following features according to the paper:

  • A greenish-brown body, with faint dark bands on the dorsal portion of the head
  • Minute dark pigmentation patches on the extremities of the lower jaw
  • Bicoloured pectoral fin
  • A short wedge-shaped pointed vomerine teeth patch, with three or four rows in the anterior portion.

 

Distribution

  • Ariosoma indicum is possibly distributed along the Indian coast, including the coastal waters of Kerala and West Bengal.
  • The Ariosoma genus has seven species, including the newly identified eel that have been documented in Indian waters.
  • Globally, there are 223 species in the genus.
  • Most of these eels have landed as by-catch in trawl landings.
