Answer:
The foot
Explanation:
Mollusks have bilateral symmetry and are coelomed protostomes, but the coelom is only represented by small residual spaces around the pericardial cavity, the gonads, some parts of the nephridia, and in some cases part of the intestine. The foot is used primarily as a means of movement. The foot is also a very important structure, although it has adapted differently depending on the classes of mollusks. It is characterized by having a really powerful and complex musculature. The most widespread use of this organ is that of locomotion, as happens with gastropods. However, in bivalves it serves to burrow or in cephalopods it helps to provide propulsion.
Invertebrate animals with the unsegmented soft body which is enclosed in shells made up of calcium carbonate are called Mollusca.
The part of mollusk's specialized in feeding, burrowing and movement are:
Foot
The Mollusca can be explained as:
- The Mollusca have the bilateral type of symmetry and coelomate protostomes which are visible as residual spaces surrounding the pericardial cavity, nephridia and gonads.
- The foot is the part that is used in locomotion and is adapted differently for various purposes in various forms of Mollusca.
- It has a complex musculature and helps in propulsion, as a mode of feeding appendage and in some for burrowing purposes.
Therefore, the foot is a specialized organ.
