Question

What are the 7 classes of mollusks?

Answer 1

Mollusks:

1. Delicate bodied, triploblastic, reciprocally even, and coelomate creatures have a place with the phylum Mollusca.
2. Mollusks can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda
   1. Aplacophora: Worm-like, non-shelled animals with a primitive body structure belong to the Aplacophora class.
   2. Monoplacophora: Monoplacophora members have a single shell that encloses the body.
   3. Polyplacophora: Members of the Polyplacophora class are known as "chitons" because they have a big foot on the ventral side and an eight-plate shell on the dorsal side.
   4. Bivalvia: Mollusks having two muscle-holding shells, such as oysters, clams, and moulds, belong to the Bivalvia class.
   5. Gastropoda: Members of the Gastropoda class feature an asymmetric body plan with a shell that can be planospiral or conispiral. The torsion on the centre of the foot along the perpendicular axis, which is changed for crawling, is their distinguishing trait.
   6. Cephalopoda:
   7. Scaphopoda: Mollusks of the Scaphopoda class have a conical shell through which the head protrude and a foot with tentacles called captaculae that are used to catch and manipulate prey.
