Scallop is the name for the bivalve mollusc of the genus Scallop, and there are about 400 species. More than 60 species in the division are among the most important marine fishery resources in the world. The shell, meat and nacre have a very high utilization value. Many scallops are eaten as food. The scallops with brightly colored and radiant patterns are loved by collectors, and the patterns are adopted as patterns of art. The scallop is a family of the bivalve subfamily. Widely distributed in the world’s waters, the tropical sea is the most abundant.
Most of the scallops we have in mind are those small creatures lying in the riverbed and quiet. Safe and harmless. Only when there is nothing threatening its existence, will he open its shell and reveal the tender meat inside. But you are absolutely not there. Under this thick outside, there are countless eyes that are watching the world silently.
Scallops have eyes and a large number. The most common European scallops have more than two hundred eyes that are distributed on the edge of the shell. It will only be revealed when there is no one in silence. These eyes are small and don’t look very clear when you look at them. However, although they are small, they can be seen far away. In other words they are a mini telescope. Scientists say that these eyes have high resolution, and collecting light in the brain is no less than the effect of the telescope.
Each eye of the scallop has a retina and lens similar to humans. They help the scallops to experience changes in light and shade to avoid predators. Since the scallop’s eyes are long on the mantle at the edge of the shell, this part has usually been removed before the table, so many people do not see its eyes when eating scallops.
When buying scallops, scallops that are uniform in size, uniform in color, and that can be quickly closed by open-touch shells are usually good scallops. Since scallops are easy to carry pathogenic bacteria such as Vibrio parahaemolyticus, they should be thoroughly cooked before eating. In addition, the scallops of orange (female) or white (male) gonads and black digestive glands are most likely to be enriched with various algal toxins. And heavy metal contaminants, it is best not to eat.
