List of cartilaginous fish of Sri Lanka

























Sri Lanka is a tropical island situated close to the southern tip of India. The diversity of fish fauna within the inland waterways and around the island is very high considering the small size of the island.[1]

Class Chondrichthyes - Cartilage fishes


Among the marine fishes, sharks and batoids (rays and skates) form a considerable diversity.[2] A preliminary checklist of Sharks around Sri Lanka was compiled by marine biologist, ornithologist, astronomer and well known diver Rex I. De Silva in 1985. It is cited as the first most comprehensive catalogue to Sri Lankan cartilage fishes. On 2016 May, he published Illustrated guide of Sharks of Sri Lanka. According to De Silva, there are 60 sharks species and 30 rays and skates found around the coast of Sri Lanka.[3][4]


Sharks are a group of fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays.

Batoidea is a superorder of cartilaginous fish commonly known as batoids or rays, but it also includes the skates and sawfishes. Approximately 560 species are described in thirteen families. Batoids are in the fish subclass Elasmobranchii along with sharks, as they are closely related. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces.
