Mollusc eye

Scallops have up to 100 simple eyes

The molluscs have the widest variety of eye morphologies of any phylum,[1] and a large degree of variation in their function. Cephalopods such as octopus, squid, and cuttlefish have eyes as complex as those of vertebrates, while scallops have up to 100 simple eyes.[2]
