क्या घोंघे गोले बदल सकते हैं? – घोंघे के बारे में सटीक तथ्य
घोंघे लंबे होते हैं, नम और, बेशक, श्लेष्म जैसा शरीर. वे गैस्ट्रोपोड मोलस्क हैं; “gastro” means stomach and “pod” मतलब पैर.
The snail’s mouth is located at one end of its “टांग” (the snail’s body). Mucus is produced by a special gland at the front of the snail’s leg.
Snails are amazing creatures. Next time you see a snail, take a moment to observe how it slowly moves along its slimy trail.
Land snails enclose the entrance to their shell with a dry mucous secretion called an epiphragm, but some do so with a structure called the operculum in aquatic snails.
Facts About Snail’s Shell
Snails are rigidly attached to their shells. Snails have an organ called a mantle – something that sort of goes around the opening of their shell, and this organ produces the calcium that makes up the shell. असल में, the shell grows out of this organ.
इसलिए, “Snails don’t change their shell when they grow up”. बजाय, the shell grows with them.
Another reason why snails can’t change their shell is because of what’s inside the shell.
Snails are not slug-like in shape, they actually have a sack of organs on their backs i.e a slimy backpack full of guts, and this vital structure depends on the shell for protection.
And even if the snail were not attached to the shell by the mantle and could technically leave the shell, it is doubtful that it would be able to return to it in such a way as to put the organ sac back in its place.
So no, snails can’t change shells. If a snail loses its shell, which unfortunately can happen as a result of physical trauma as well as certain parasites and diseases, it will die.
Few people have tried to save snails by trying to put the shell back on and by regularly spraying the snail with water to keep it from drying out, but it is impossible to save such a snail. When a snail loses its shell, the only thing you can do is to kill it quickly and painfully to put it out of further pain.
यह कहने के बाद, if you are about to pick up a snail and it is firmly stuck to something, never, ever try to tear it off the surface by its shell.
This can be very painful at best, and at worst can cause permanent damage to the mantle, resulting in the loss of the shell.
Always kind of run your finger or, better yet, a smooth wet object, such as a wet spoon, under the snail’s head and keep doing this until it has broken away from the surface enough that you can grab it without problems.
संक्षेप में, snails cannot change their shells, just as a human cannot change it’s backbone.
A shell is like a snail’s backbone, Note That!
