People who live near the sea often eat shellfish.
Food is fed, and some people have heard some fishermen say that shells can also walk. And said that shellfish go very fast, so many netizens expressed curiosity, they have eaten shellfish and have not seen how shells walk, and they have always thought that shells' actions rely on the impact of seawater. However, the de facto shellfish are still walking.
Next, let's take you to understand how the shell moves. <>
Biological division of shellfish, they are classified as mollusks.
Their shell shells, mainly their exoskeletons.
It is not particularly related to their overall physiological structure, and is mainly used to protect their bodies. Nowadays, shellfish mainly live in the ocean, and they can be seen almost everywhere from the near sea to the deep sea. But there are actually many varieties of shellfish, some shellfish are legged, some shellfish belong to the footage, they are not able to move at will, these shellfish, their main way of movement is to rely on the contraction of their own body, let their body form a buoyancy inside, and then float on the water, and then move back and forth with the direction of the current, which is why we sometimes see shells on the beach.
And some shellfish are legapods, which can move autonomously, and there are some shellfish and the octopus squid that we usually see.
They have the same way of locomotion, they stick their feet out of their shells during normal exercise, use their muscles to exert force, push their bodies forward, and the foot glands on their feet can secrete mucus to help them move in the seawater. When shellfish are on the ground, they tend to walk slower when they encounter sand. That's why shells walk fast, but it's actually when there is water on the beach near the sea that they move so quickly.
The above are some of the rumors about the shell walking, after breaking them down, you can know how the shell acts, I hope this knowledge can help you.

I've seen shells walk, and shells walk diagonally like crabs, up to 10 meters a minute, and I think it's really fast among marine animals.

Shells are mainly advanced by strong air currents and the recoil force of the currents, and shells are mollusks that wriggle to form a walking posture.
-
I've seen it. Although they do not have feet, they move through their shells. You can walk several kilometers in a minute.

1. Advance by the recoil force of the strong air flow or water flow generated by the rapid closure of the two shells.
2. Shellfish belong to the Valve Gill (or Bivalve) in the phylum MolluscsBecause there are generally 1-2 shells on the outside of the body, it is named. Common oysters, mussels, clams, clams, etc. are all in this category. There are about 10,000 species in existence, 80% of which live in the ocean.

Shellfish can walk.
For example, mussels have an axe foot, and snails and snails have a flattened soft foot. Of course, there are other shellfish such as squid, which use a compression cavity to recoil; There are also some who have brachiopods and move directly.
