Aspects of the Host - Commensal Relationship between a Palaemonid Shrimp ('Pontonia domestica') and the Pen Shell ('Atrina rigida')

摘要

Sixty pen shells (Atrina rigida), were collected and examined to determine the prevalence and morphometrics of the commensal shrimp (Pontonia domestica). The spatial and sexual distribution within the shell of the host, and the reproductive states of the shrimp were also investigated.
