A new record of a rare species Masturus lanceolatus (Point-tail sunfish) from Chennai coastal waters, India

297-301A single individual point tailed sunfish Masturus lanceolatus was landed at Kasimedu fishing harbour, Chennai coast by gill netter, for the first time. In the present study, morphometrics and meristic measurements of the sunfish were made, which was found to be 120 cm long and weighed approximately 44 kg. The specimen has been compared with earlier reports

First DNA Barcoding Based Record of Lysiosquillina Maculata (Fabricius, 1793) (Crustacea: Stomatopoda) From Chennai Coast, Tamil Nadu, India

Abstract Taxonomic identification of mantis shrimp Lysiosquillina maculata through DNA barcoding analysis collected from Kasimedu fisheries harbour, Chennai coast, Tamil Nadu, India. The mitochondrial cytochrome oxidase sub unit I gene (mtcoI) with 650 bp region was sequenced for phylogenetic analysis. The present record, mitochondrial gene sequences were used to identify the mantis shrimp Lysiosquillina maculata. This is the first confirmed record of Indian waters and the mt COI sequence was deposited in GenBank. The neighbor joining method was used for phylogenetic analysis. The pair wise genetic distance calculated with 08 closely related species varied form 0.03-0.404%. Phylogenetic tree based on 13 protein coding genes shows that Lysiosquillina maculata has a closer phylogenetic relationship to Harpiosquilla harpax.</jats:p
