The author apologises that upon publication a paragraph at the start of page 2 of the article references a 1 year period but listed the wrong end month and should have read as below:
Live D. scortum clams were collected at monthly intervals for a period of 1 year from February 2009 to January 2010 from the intertidal sandy beach at Padukere (13°20′51.80′′N 74°41′30.92′′E) near Udupi town (Fig. 1).
