A study on species diversity of gastropods and bivalves in Kannur, South-West Coastal Area, Kerala
The study was conducted on the diversity and distribution of bivalves and gastropods in South-West coastal area precisely Kannur district of Kerala, carried out in three different sites namely Thalassery (11.7533°N, 75.4929°E), Dharmadam, (11.7775°N, 75.4703°E) and Muzhappilangadu (11.7972°N, 75.4470°E) during low tide and moderate sunny morning of November 2020. A total of 11 species of marine gastropods and 13 species of marine bivalves representing 9 and 7 families respectively were identified in relation with the shell obtained, colour, pattern, types of coiling and other morphological aspects of shells. A set of gastropods and bivalves were identified from the study based on their species diversity and features. A solid understanding of mollusc is now more relevant and timely than ever before. This is because human are beginning to fully appreciate that the marine environment and the organisms that live in that environment are critical to well-being and survival of the flora and fauna.
