Mollusc eye refers to the light-sensitive organ possessed by mollusks. However, the term may vary depending on the type of mollusk. For example, in the case of cephalopods like octopus and squid, the mollusc eye is often referred to as a camera-like eye due to its complex optical system. Other synonyms for mollusc eye include ocelli, which are simple eyes composed of single photoreceptor cells found in gastropods and bivalves. Some bivalves also possess lens eyes, which are similar to camera-like eyes but less complex. Hence, the term mollusc eye may encompass various structures depending on the mollusk in question.
