Abstract

This study documents the occurrence of deep-water spider crab, Paramaya mulli, along the Southwest coast of India. Initially described in 2018 from Tamil Nadu on the east coast, this species was subsequently noted in 2020 in Gujarat on the west coast. The specimen was retrieved from by-catch discarded by commercial fishing trawlers at Sakthikulangara fishing harbour off Kollam, Kerala. Identification as Paramaya mulli was established through a combination of morphological and molecular data. Both 16S ribosomal RNA (16S rRNA) and cytochrome c oxidase I (COI) sequences from the current specimen were compared with the NCBI sequences of previously identified specimens. Phylogenetic analysis, using mitochondrial gene sequences (16S: OQ456467, OQ456468) from the present specimen and sequences obtained from NCBI GenBank, was conducted to elucidate the relationships of genus Paramaya.
