Mollusks exhibit diverse respiratory structures depending on their class. Aquatic mollusks, such as bivalves and gastropods, typically possess gills (ctenidia) for gas exchange in water. In contrast, terrestrial gastropods often have a modified lung-like structure, known as the pallial cavity, which facilitates respiration in air. Cephalopods, on the other hand, have highly efficient gills and can also use their mantle cavity to aid in respiration and locomotion.

What houses a mollusk's respiratory structures?
A mollusk respires through structures called ctenidia (gills), which are housed in the mantle cavity of most mollusks. The mantle cavity is a space between the mollusk's main body and its mantle, an organ with numerous important functions, including shell creation and osmoregulation.
Where are the organs of a mollusk located?
in the respiratory system.
Where are the body organs of a mollusk located?
in the respiratory system.
What are three classes of mollusk?
There are seven classes of mollusks. These are Gastropoda, Bivalvia, Polyplacophora, Scaphopoda, Cephalopoda, Aplocophora, and Monoplacophora.
Do mollusks have a pores?
Mollusks do not have pores in the same sense that some animals do; instead, they have a mantle cavity that houses respiratory structures, such as gills or lungs, depending on the type of mollusk. The mantle itself can secrete a shell in many mollusk species, and while they may have openings for excretion and respiration, these are not considered pores in the typical biological sense. Overall, their anatomy is specialized for their diverse habitats and lifestyles.
Is lobster a mollusk?
Lobsters, are in fact, arthropods. Arthropods must have segmented body pieces and have an exoskeleton. While it may be true that that lobsters have shells, it does not have the mantle cavity that confirms that it is a mollusk.

Is a rock a mollusk?

What type of mollusk does not have a radula?
The radula (or some form of the radula) is found in all classes of mollusks except bivalves (organisms with two shells such as clams).
