Abstract

Marionia pambanensis (O’Donoghue, 1932), commonly named Pamban sea slug, is a dendronotid nudibranch belonging to the family Tritoniidae, phylum Mollusca which was first described from the waters around Pamban Island, south-eastern coast of India. This species was previously reported only from the coasts of Tamil Nadu, Goa, and Maharashtra. The current study provides the first record from the Okha coast, Devbhoomi Dwarka district, between the Gulf of Kutch and the Arabian Sea in Gujarat. Distinguishing features from morphologically similar M. olivacea are mentioned.
