    I believe that when you go to eat seafood, you will generally order scallop garlic vermicelli, which is very delicious! Do you know how the scallops move in the sea? I always thought that shellfish were sunk in the sea, and they couldn't move hahahahaha!

    It seems to be too lonely and unheard!

    Scallops are said to have no legs, but they can swim! The way you swim is not cute! I can laugh for a day!

    The biggest natural enemy of scallops is the starfish, some of which can eat more than a dozen scallops in a day! Therefore, in order to defend themselves against predators, scallops will pat two shells to push the water forward to avoid predators.

    Scallops are delicious, nutritious, and sea cucumber, abalone are equally famous, and listed as the three major treasures in the seafood, unlike other mollusks, the scallop adductor muscle, that is, the shell pillar accounts for a large proportion of the body, but also the edible essence! Scallops are commonly found in the sand and fire and clean seawater, feeding on smiling creatures, relying on cilia and mucus to move food particles into the mouth, can swim, bivalve intermittent slapping, spewing out of the stream, with its reaction force to push itself forward, eggs and sperm sent to the water for fertilization, hatched larvae swim freely, and then the larvae are fixed at the bottom of the water to develop, and some can crawl and move! It looks like a Pac-Man eating seawater in one bite.

    However, it should be noted that despite being able to swim, the efficiency is not comparable to that of fish, and you will fall back to the bottom of the sea exhausted after swimming up to five or six meters at a time, and you will need to rest for several hours before you can swim the next time. However, there is no shortage of currents in the ocean, and scallops may be a "free ride", and perhaps it is not impossible for scallops to escape.

    Scallops swim no more than one meter at a height of no more than half a meter per second, swim up to five or six meters at a time before falling back to the bottom of the sea exhausted, and most of the rest will take several hours to fully recover.

    Scallops can swim, but the way scallops swim is different from ordinary creatures, and the scallops swim by using the shells on both sides of the shells, through the opening and closing of the shells to generate power, spray out water, and then use them to destroy the way to push themselves forward. Most of them inhabit the shallow sea from the low tide zone to about 100 meters of the land of several fibers, and live freely or camp. <
