A new record of Opisthobranch, Tayuva lilacina (Gould, 1852) and notes on Euselenops luniceps (Cuvier, 1816) from the Andaman Sea, India

Abstract

The present study reports occurrences of two sea slugs namely, moon headed side-gilled slug Euselenops luniceps (Cuvier, 1816) and spotted foot nudibranch Tayuva lilacina (Gould, 1852) from the Andaman Sea. Euselenops luniceps (Cuvier, 1816) is a very rare species previously recorded from the Andaman and Nicobar Islands without any precise geographical location details, and this study confirms the occurrence of E. luniceps (Cuvier, 1816) from the North & Middle Andaman Islands. The spotted foot nudibranch, T. lilacina (Gould, 1852) is first time recorded from the Andaman Sea. Previously, these two species were recorded from both the east and west coasts of mainland India. These species are illustrated, described, and their distribution details in the Islands are provided.
