mollusc eye
The molluscs have the widest variety of eye morphologies of any phylum, and a large degree of variation in their function. Cephalopods such as octopuses, squid, and cuttlefish have eyes as complex as those of vertebrates, while scallops have up to 100 simple eyes.〔Land MF and Fernald RD (1992) ("The evolution of eyes" ) ''Annual review of neuroscience,'' 15: 1–29.〕
==Diversity==
Eyes have evolved independently between seven and eleven times in the molluscs,〔('Camera eyes in gastropod molluscs" ), mapoflife.org〕 which goes some way to explain the diversity of eye types observed. Molluscs have eyes of all levels of complexity, from the pit eyes of many gastropods, to the pinhole eyes of the ''Nautilus'', to the lensed eyes of the cephalopods. Compound eyes are present in some bivalves, and reflective 'mirrors' have been innovated by other lineages such as scallops.〔 As well as varying in complexity, the eyes of molluscs span a huge range in size; they may be from to across.〔
