Taxonomy and diversity of rock and coral boring bivalve genus Lithophaga from Visakhapatnam coastal waters, east coast of India


Author(s): Venu Devara

Abstract: There has been a renaissance of taxonomy and related subjects such as abundance, ecology and distribution of species as biodiversity in the last two decades. Diversity of rock and coral boring organisms comprises the most specious assemblages and species specificity of invertebrates. Diversity of rock and coral boring bivalve species taxonomic compositions were described along Visakhapatnam off shore region. They occurred on the huge cement concrete boulders and corals in the Visakhapatnam fishing harbour region and the entrance channel region of the port. Two species of genera Lithophaga were collected and observed in the Visakhapatnam offshore region. Diagnosis based on shell characters are given for Lithophaga laevigata (Quoy & Gaimard, 1835) and Lithophaga teres (Philippi, 1846) from the family Mytilidae. Morphological comparisons of shells are made for these two species. It is observed that the infestation of the boring organisms of different bivalves is very highly bore at the bottom region, at the junction of the arms region of the coral. The bivalves bored into different substrates such as limestone, calcareous rocks, sand rocks, rubber material, and polyvinyl, plastic, wood, live and dead coral. The diversity of two species of Lithophaga genus is abundantly available in Visakhapatnam coastal waters.
