What is the symmetry of Mollusca?

Mollusks are generally considered a phylum of bilaterally symmetrical animals, although there are also many asymmetrical species. Bilateral symmetry means that an organism can only be divided into two equal halves if it is cut from top to bottom along the middle of the anterior-posterior (front-back) axis.

Is Mollusca asymmetrical?

Animals in class Gastropoda (“stomach foot”) include well-known mollusks like snails, slugs, conchs, sea hares, and sea butterflies. These animals are asymmetrical and usually present a coiled shell.

Which mollusks can camouflage?

octopus
Cephalopods — squid, octopus and cuttlefish—all have chromatophores, organs with pigment cells that the animals control with muscles, and use for camouflage and communication. The animals can rapidly change the color patterns on their bodies.

How do molluscs camouflage?

Since octopuses don’t have protective shells, they have developed a complicated system of chromatophores to camouflage their bodies. It uses specialized chromatophore cells in its mantle to blend in with its environment.
