Do mollusks have antennae?
Despite their differences, mollusks do share several things in common. Mollusks have three distinct divisions of their body. The head contains the sensory equipment (eyes, antennae, etc) and the primitive brain. Most mollusks have a special tongue-like organ known as the radula.Click to see full answer.

Despite their differences, mollusks do share several things in common. Mollusks have three distinct divisions of their body. The head contains the sensory equipment (eyes, antennae, etc) and the primitive brain. Most mollusks have a special tongue-like organ known as the radula.Click to see full answer. Regarding this, do mollusks have a body cavity?Both flatworms and molluscs are triploblastic, bilaterally symmetric, and cephalized. But molluscs have developed a true coelom, an internal body cavity enclosed by mesodermal membranes. The coelom in molluscs, however, is strangely reduced to a small space around the heart, sometimes called a hemocoel.Beside above, what type of skeleton do molluscs have? Unlike the internal skeleton of humans, mollusks actually have an external skeleton. This exoskeleton protects the animal’s soft inner body parts and acts as a sight for muscle attachment. Subsequently, one may also ask, what does a mollusc eat? Mollusks eat many types of foods depending on their species. Many mollusks that have their body between two shells are herbivores, they mainly feed on algae. Squids and octopuses are predators and feed on fish and other sea creatures. The mollusk snails are mixed with herbivores and carnivores.What traits do all mollusks share? Main characteristics of Mollusca : Unsegmented soft body with bilateral symmetry. Presence of an internal or external shell. A toothed tongue (made mostly of chitin) called the radula. A mantle which is a fold in the body wall that lines the shell. Muscular foot (and/or tentacles in some).
