Do Snails have teeth?
374507
Yes! They have about 25, 600 teeth and can chew through about anything!

A snails shell is very thin and is not for protection from predators but rather to conserve its body fluids the sun is a snails worst enemy and the rain its best friend. They come out in the rain to forage for food and to move to new locations with the possibility of contacting a mate or more suitable living quarters.

ok.. so in the past, our smart ancestors needed all those teeth. as one of my colleagues has said, they needed to chew hard food and be crunching on those bones, meat and so on. but that's not it although they had large jaws (which in due time and evolution shrinked) they also didn't have toothpaste!!! so, their teeth would decay in time, and they would do anythg to get rid of those ones that pained them much (like bang it to a tree so that it falls, and or chew on a large apple so that tooth is stuck on it, w/o going to doctor to fix a small decay. so they would end up losing most of their teeth at the age of 18. but that was ok for they would have extra fantastic 4 to the rescue.\n\nnow, since we have toothpaste, and dentists and loads of other stuff to protect our teeth, our jaws shrunk and we were in all ways cooking food and not crunching on big nuts like desperate fools, rather use special tools to break nuts & so on. so, we proected our teeth, and eventually we don't need those extra four... which are a surplus extra by all means, and they would hurt our mouth when they come out... so BYE BYE ADDITIONAL MOLARS! OUCH!

The mollusk are killed to retrieve the pearls. Sometimes the pearls form in among the fleshy parts or on the inside surface of the shell where the nacre is made. In either case the mollusk is killed so the pearl can be removed from where it may be attached still to the shell or inside the flesh. In general, the oysters are opened just like you see at the fish market, with an oyster knife and the rest is history.\n\nPearls are formed by any mollusk that can form a shell. The most prized pearl comes from the Pearl Oyster, but other pearls can be found in clams both saltwater and freshwater varieties, abalone, mussels, conch, and so on.

the snail's body needs to be moist all the time. the water not only protects the snail it also helps lubricate it. the salt absorbs the water from the snail's body.

There have been some pretty weird ones out there, but the weirdest one of all is yet to come.\n\nI get done answering this question, then I stumble on this one:\n"how many teeth as a water snail got they do have them?"

It's a Gastropod. A kind of sea snail.

Hmm. I don't think seashells are formed from sands. Seashells are marine creatures to be exact, marine snails. Though I have yet been able to verify, I believe the reproduction process of seashells are similar to that of a snail. That is some seashells are hermaphrodites, producing both spermatozoa and ova, others are either male or female. They inseminate each other to internally fertilize the ova, thus producing fertilized eggs.

They could *be* shark teeth. There are plenty of places where you can pick them up right off the sand if you know where and how to look for them.

two snails (most are hermaphroditic, not you do not need to figure out sexes, each is both). \nhigh humidity (though don't drown them)\nsome soil to bury the eggs in\n\nand it probably has to be the right time of year (correct temperature, light cycle). \n\nFind out what species you have and look up on google if you can find something about specific requirements for the reproduction of your particular snails

The digestive tract is complete and ciliated, with a mouth, anus and complex stomach. The pattern of the stomach varies according to the mollusks diet.  Food is taken up by cells lining the digestive glands arising from the stomach, and then is passed into the blood.  Undigested materials are compressed and packaged, then discharged through the anus into the mantle cavity and are carried away from the animals in the water currents.  This packaging of wastes in solid form prevents fouling of the water passing over the gills. \n        Excretory functions are carried out by a pair of nephridia, tubular structures that collect fluids from the coelom and exchange salts and other substances with body tissues as the fluid passes along the tubules for excretion. The nephridia empty into the mantle cavity.

Mud-eater. Limnivores feed on algae and the micro-organisms that live within the substrate. These fish will also feed on small worms and shell fish such as snails.\n\nThese fishes have a small stomach and a long intestine and will feed almost continuously throughout the day.

Yes they do :) My grandma used to keep lots of them, and i could see their tongue each time they tried to bite me !

normal...no, but like i explained in aother answer, extra teeth are created by epithelial pearls. the epithelial pearls come from the degeneration of the dental lamina in your mouth when your were a foetus. usually the destruction is complete, but in your case, i guess the destruction wasnt done well. (cause by traumatism?)

Molluscs have an organ known as a mantle. It is the body wall covering beneath the shell. The outer layer of this organ secretes calcium carbonate using calcium from its blood. They can also secrete some proteins which give the shells colors and patterns while the mollusc is living. The inner layer of the shell is composed of nacre, which is a composite of calcium carbonate and organic materials. This is the material that makes the inner part of the shell iridescent, and the coating that makes pearls.

They are not particularly closely related, but they are both in the order Rodentia.  They probably split somewhere between 65-55 million years ago (though some genetic studies suggest it could be much older).\n\nThey share characteristics of rodents: evergrowing incisors, 1 top incisor and 1 bottom incisor (per side).  They have no canines, the maxilla is a part of the zygomatic arch.  There are additional physical characteristics as well as genetic ones.

Well a snail is an hermaphrodite \nthey are both male and female sex \nthey shoot "love darts " from one to each other then store the sperm until needed \nsome snails hibernate in winter \nSnails can live for years .. but due to natural predators oftern die quite young
