TL;DR: Marine boring bivalves responsible for bioerosion processes of lapideous artefacts, recovered in the Gulf of Pozzuoli (ancient Puteoli) and in the Blue Grotto in Capri Island (Naples, Italy), were examined as mentioned in this paper.
TL;DR: This is the first report of Barbatia genera of Arcidae family (Bivalvia:Mollusca) from the South east coast of India.
Abstract: New records of five bivalve species are reported in this paper. This is the first report of Barbatia genera of Arcidae family (Bivalvia:Mollusca) from the South east coast of India. Five species of Arcidae from Barbatia genera were obtained from the sea shore of Thiruchandur and Veerapandiyapattinam in Tamil Nadu. These places are come under the Gulf of Mannar Region. Arcidae unites a group of marine bivalves that inhabit rocky substratum as well as sand and mud. They are distributed in warm tropical waters from the midlitoral zone to great depths. The five species namely Barbatia amygldalumtostum (Roding, 1798), Barbatia barbata (Linnaeus, 1758), Barbatia foliata (Forsskal in Niebuhr, 1775), Barbatia obliquata (Wood, 1828), and Barbatia candida (Helbling, 1779) are classified and described based on their morphological characters. For species level systematic arrangement periostracum characters were considered. Five morphological characters were used for identification. The identified specimens of the family Arcidae (Bivalvia:Mollusca) had deposited in the Marine Biodiversity Museum of CMFRI , Kochi, Kerala, India.
