Scallops have a lot of eyes, why do they have bad eyesight?

Lund University and Weizmann Institute of Science in Israel published a report in the academic journal Science. Scallops are synonymous with bivalve molluscs of the genus Scallops, with more than 400 species.

Scallops are synonymous with bivalve molluscs of the genus Scallops, with more than 400 species. More than 60 species of the Section are one of the most important marine fishery resources in the world.

Shell, flesh and nacre have extremely high utilization value. A lot of scallops are eaten as a delicacy. Brightly colored scallops with radial patterns are loved by collectors, and the patterns are used as patterns for works of art.

Scallops are a family of pearl oysters in the bivalve pterygoform subclass. More than 60 species of this family are one of the important marine fishery resources in the world, and shell, meat and nacre have extremely high utilization value.

According to the report, the scallop's eyes are located at the tip of hundreds of tentacles that can extend out of the shell, and each scallop has 200 eyes the size of a seed.

These eyes grow in a place called the mantle on the periphery, unlike ordinary organisms that focus the light source with a lens, the scallop has a multi-layer concave lens at the back of each eye, and the concave lens will be connected to a square lens, so that the image can hit the two layers of retina with different functions, and the wavelength of the light is clearly reflected, so that the scallop's vision can maintain a wide field of vision.

In the ocean, there are very few places to use the eyes, and the eyes are degenerate.

Because the eyes of scallops grow at the mantle (skirt) at the edge of the shell, vision is not good.

Long-term in the deep sea, not using glasses, causing degradation.

The eyes have deteriorated, but they have not deteriorated in perception.

The eye grows in a place called the mantle on the periphery.

Because scallops are not very useful to the eyes in the sea, they have poor eyesight.

Because there are very few places to use their eyes in the sea, their eyes are degenerated.

The structure of the scallop eyes is very complex, resulting in.

The scallop eye structure has optical advantages, and many large reflecting telescopes also use a densely spaced mirror. The inlay crystal lens minimizes light dispersion due to defects in the crystal surface and reduces the loss of light as it passes through the lens.

If you look closely at a live scallop, you'll be surprised to see that the scallop is staring at you as well. In the edge depression of the scallop shell, there are dark dots, which are the eyes of the scallops, and there are more than 200 of them. Scallops have human-like retinas and lenses in each eye, which help them sense the changes in light and shade to avoid predators.

Since the eyes of the scallop grow on the mantle (skirt) at the edge of the shell, this part is usually removed before it is served, so many people do not see the eyes when they eat the scallop.

No eyes, at least I didn't.

How many eyes did Fan Hui Nabe miss?

There are more than 200 of them
