Types of Eyes in Mollusks

In most mollusks, the sensory organs primarily consist of a pair of eyes. The complexity of the eyes varies among different groups of mollusks. The types of mollusks with the most complex eyes are:

A) Gastropods (Chitons) Gastropods, also known as chitons, have the most complex eyes among mollusks. Their eyes are capable of detecting light and dark, and they are located at the edge of the mantle.

B) Bivalves Bivalves, such as clams and oysters, have relatively simple eyes compared to gastropods. Their eyes are typically composed of a few photoreceptor cells and are primarily used to detect changes in light.

C) Cephalopods Cephalopods, including octopuses, squids, and cuttlefish, have the most advanced eyes among mollusks. Their eyes are similar in structure to vertebrate eyes and are capable of forming images. Cephalopod eyes have a lens, retina, and cornea, allowing for sophisticated vision.

These distinctions in eye complexity reflect the diverse adaptations of mollusks to their environments and lifestyles.
