Miami – Scallops may look like simple creatures, but shellfish have 200 eyes that work remarkably like a telescope, using mirrors to focus light, researchers say.

The eyes of most creatures have lenses that focus light. [19659002] But scallops have concave mirrors in the back of their eyes.

Scientists have known since the 1960s that Pecten's scallops are seen reflecting the light of these concave mirrors on the retina, the report said in the journal Science . Some crustaceans and deep-sea fish also have eyes like this.

But now they have found a way to look deeper into these mirrors than ever before, using a microscope that quickly freezes samples so they do not dehydrate and retain their shape.

Spatial view

The result is the first view of a mosaic of small mirrors and crystals, carefully arranged inside small poppy seed eyes that are aligned at their outer edge, known as the mantle.

Each mirror is layered, reflecting the wavelengths of light in its habitat and giving them a spatial view of their surroundings.

Each mirror is also "tiled with a mosaic of square crystals, minimizing surface defects for a clearer image," said the Science report.

"The mirror forms images in a double-layered retina, to separately represent the peripheral and central fields of vision."

While it is still difficult to know what the world looks like a scallop, r Researchers say that this well-sharpened peripheral vision probably helps control scallops and guides their movement while swimming, which allows you to badess what things are static or moving.

The findings illustrate the "remarkable" ability of scallops to develop their own complex. The study was led by researchers from the Weizmann Institute of Science in Israel and the University of Lund in Sweden.
