Recent studies have revealed that many marine invertebrates are closely associated with diverse microorganisms, frequently resulting in the production of compounds of biomedical interest. During the present investigation mitochondrial cytochrome oxidase I gene sequences was used to identify the tunicate asPolyclinum madrasensis (Sebestian, 1952) this is the first report of this species worldwide. Solitary ascidian Polyclinum madrasensis was collected from the Gulf of Mannar coast in April 2011. The amplified product was sequenced by a commercial lab. The size of the COI was 643 bp in length. The processed sequence was deposited in Gen Bank and got the accession number Polyclinum JN 107814.  This study highlights the power of molecular method for species identification and India’s need for an extensive, systematic molecular inventory of its existing marine invertebrate biodiversity.
