Scallop often is regarded as cate edible, do nevertheless you know, one looks ordinary without strange scallop, have 200 eyes actually, and every eye is rear high-rise concave lens, concave lens still can join again on one square model crystal, make video on the retina that can play two distinct effect, the eyesight that lets scallop can resemble binoculars kind euqally outstanding. The scientist takes the place of to know from 1960, division of sea fan clam (the shellfish biology of Pecten) is OK by concave mirror glances upper part retina sees an object. Certain crustacean animal and abyssopelagic fishes also have such eye. Academy of science of Israel Wei Ciman (Weizmann Institute Of Science) and Swedish Longde university (the researcher of Lund University) , in " science " academic periodical publishs an article, use " refrigerant electron microscope " the eye of postmortem scallop is refrigerant section, discovery has complex visual system unexpectedly among them, and this discovers what also be thought to conduce to artificial eyeball to transform. Unlike majority biologic eye, the eye of scallop besides have get together smooth crystal, still have concave lens, these small glasseses and crystal present mosaic state, the local; that orderly platoon is in to be called to cover film these concave lens can enter radial reflex two retina, a retina can build an eye of ahead video, another is to be able to make brim perspective clearer. Researcher is conjectural, scallop uses different retina very likely namely, escape plunders the charge of the person that feed, and search for suit to rest foraged place. Additional, the crystalline lens of scallop is discovered to be the appearance of level off diamonds, can will video on the retina that is hit in two different function, the eyesight excel that lets scallop is other animal, can have more like the good vision like binoculars.
