why do snails die when u put salt on them?

salt absorbs water.  Snails are made mostly of water. Thus pouring salt on snails causes the water stored under the membrane skin of the snail to come out resulting in the snail "melting."\n\nAlso works with tobacco.\n\nMessage from the sponsor: THIS IS CRUELTY TO ANIMALS!!! DON'T DO IT!

because it has NaCl in it

Salt is bad for EVERYONE. Not just guys. It's good to eat a little because it has Iodine, a necessary nutrient, in it. To much can cause high blood pressure and/or clog your ateries.

Salt is not salt.\n\nSea salt contains a higher percentage of Potassium Chloride (KCl) than table salt which is mainly sodium Chloride (NaCl). It is the sodium content of salt that can cause damage if too much is ingested. The sodium content of the body's blood, interstitial and intracellular fluids is the key determinant in the volume of water the body retains.\n\nGenerally the more water the higher your blood pressure.\n\nSubstituting the sodium with potassium helps to lower the associated risks of excess salt intake.\n\nHowever excess potassium ingestion hasw problems of its own including dysfuntioning of electrically active cells (heart, nerves, muscles). But the concentrations needed are quite high.

Even though our blood chemistry is rich in sodium like sea water, we drink fresh water not because of taste but rather biology.  Our bodies need a very fine balance of water content and sodium content.  If the sodium concentration is too low, our cellular functions cease and we die.  If the sodium concentration is too high, our cellular functions cease and we die.  \n\nLand animals lose water through sweat, urine, stool, as well as just by breathing.  We need to replace the water that we lose or else the sodium balance will be tipped and we will die of dehydration.\n\nHuman beings are unable to drink sea water because our kidneys are not efficient enough in concentrating the urine to eliminate the excess salt and in effect will cause the sodium concentration and ultimate kill us.  There are animals that have special adaptations that allow them to survive on salt water, such as more efficient kidneys, glands that secrete the excess salt from their bodies, and better methods to conserve body water... these particular creatures would likely suffer problems if they drank fresh water and die of "water poisoning" (i.e. loss of salt.)\n\nIn this case, biology has dictated taste.  You can guess what happened to everyone else who didn't develop the taste for fresh water...

Since you said please help, I will try to answer this question.  A snail does not have the same kind of digestive tract as a more highly evolved species of animal.  Therefore by nature, a snail being a more primative animal will lack certain enzymes which break down its food matter for absorbtion to provide fuel for its other living cells.  This means that the animal can only extract some nutrients from its food source resulting in a partial digestion.  therefore the feces from a snail may appear similar to the original food source both in texture and in color.

could be a chemical reaction to processed salt (iodine...etc)...try switching to sea salt.

salt water is heavier than fresh water. If the water is salty enough, the egg will float. Otherwise, it will sink.

It should be noted that you are salty. We have a natural salinity that is important to maintaining homeostasis. Any disruption of our salinity can cause serious metabolic and physiologic problems.

the only thing that I can think of, is that when you are putting so much water into the fly it messes up it's electrolytes...therefore the nerves can't do anything because they will never reach their threshold and have an action potential.  Mostly the potassium and the sodium, and so when you put salt (which contains sodium) on the fly is causes the electrolytes to re-balance.\nMaybe the fly isn't really dead...maybe it's just paralyzed?\n\nThis is just a theory since I've never heard of this phenomenon myself.

you pour salt on them they curl up and die and dry out... it's real nasty

LMAO!!!!! thats a funny question! have u seen how a snail eats? its so cute!! worm would probably be a bit too big for a snail to eat, and a worm would be too rough for snails to bite. snails have no teeth...they're cute! annnd yeah, they're vego's!

It's because salt is an electrolyte, a substance containing ions (charged atoms or molecules). The charges are what allow the atoms to conduct electricity, I think.

Sea salt melts it quickly.\n\n\nPeace

That depends entirely on the fish species and its age and lifestage.\n\nAs others have pointed out many fish like trout or eels will move from fresh water to salt as a normal part of their life cycle. Many other fish trevel between fresh and salt water at will.\n\nHowever if you take a purely freshwater fish, one that has evolved to live exclusively in fresh water, and you drop it into salt water it will  shrivel up and die.\n\nFish don't have waterproof skins. When you place a freshwater fish in salt water osmosis will draw water out of its body far faster than it can be replaced. The fish will become dehydrated and basically die of thirst.

How about the reaction slugs have to salt?
