Anatomy of soft body of Pugilina cochlidium (Linnaeus, 1758) and P. erecta (Vermeij & Raben, 2009) (Neogastropoda: Melongenidae) from Thondi Coast-Palk Bay in Tamil Nadu, India

Abstract The species of Pugilina cochlidium (Linnaeus, 1758) and P. erecta (Vermeij & Raben, 2009) has been studied in the present study. The female can be differentiated from the male by the absence of the cephalic penis and a complicated genital aparatus visible through the mantle skirt in bot...

description Abstract The species of Pugilina cochlidium (Linnaeus, 1758) and P. erecta (Vermeij & Raben, 2009) has been studied in the present study. The female can be differentiated from the male by the absence of the cephalic penis and a complicated genital aparatus visible through the mantle skirt in both the sexes. In other aspects of the external features of female are quite to males. In both species the digestive system was similar with few differences in structure between each other. It consists of buccal mass, proboscis, salivary glands, accessory salivary glands, oesophagus, stomach, intestine, rectum and anus. The nervous system in both P. cochlidium and P. erecta is constituted by six ganglia which forms the circumoesophgeal ganglionic ring. Among the neogastropods there is a similarity in the organization of the reproductive systems. The female reproductive system is more complicated than that of male. The sexes are separated in these two species. The gross morphology of the reproductive system of P. cochlidium and P. erecta was almost similar. The present study aims to describe the digestive system, nervous system and reproductive system of two gastropods species P. cochlidium and P. erecta.
