Heya!!
Molluscans are triploblastic coelom area and usually with bilateral symmetry. They are terrestrial, marine and fresh water inhabitants.
Soft bodies with protective hard shell. Shells are of various shapes-conches, cowrie shells, flat and spiral, etc. The body is unsegmented and divided into a head, a ventral soft and muscular foot, and a dorsal visceral hump. The skin is soft and over the hump it forms a mental. The visceral hump contains the main digestive and circulatory organs.
Hope it helps✌️✌️
