The Apple snails crawls to the surface, and lets out foot-funnel to trap all the particles floating on the surface. They eat plants, and algae and are mostly vegetarian. Apple Snails can eat everything in their environment, but they prefer soft and easier to digest foods. Some times when the water gets down to 10 degrees Celsius, the Apple snail can't survive. The Apple Snail can fill its lungs to float on the surface. Most snails apple snails prefer calm waters, to choppy waters like rivers. Apple snails live in swamps, ditches, ponds, rivers, and lakes. The Apple snail is native to South America. This map shows the location were the Apple Snails are normally located in the US Not only that once again they can float which can get them moving quickly if they need to. Which leads to the question of where are the fish in the place where its invading? most fish where its invading either haven't discovered it or stop eating it because of a foul taste. Although a bit shocking a lot of fish especially spineless ones will suck the snail out of its shell and even if it cant eat the snail the fish will completely destroy the snail. The Apple Snail has to eyes and sense bristles which give it a very strong olfaction (sense of smell) because of this they can find food surprisingly fast. Which can get really surprising especially if it just hangs on the wall of an aquarium. their siphon can reach up to 4in (10cm) long. The Apple Snail has gills but is used to a less oxygenated water so they usually wait till they think its safe and breath up for water from their siphon. The Apple will eat just about anything causing some problems which will be mentioned later. Given their size the Apple snail is said to be the biggest living fresh water snail on earth. One of the worst parts of the Amazonian Apple Snail is its eggs which it lays by the thousands in pink sticky egg cases. They also have little Siphon's that allow them to breath just under the surface of the water which comes in handy when the floating around. So their is no way to get rid of them by eating. These snails also contain many parasites' which include rat lungworm and many others that infect humans if they eat the snail. In that case whenever their is a flood in that area the snails will float every where and continue spreading. That also may seem like a good thing until you considered how they supposedly go their in the first place. Not only that they can manage to trap enough air in their shell to float. Well, it turns out that they blend in with the bottom of a muddy bank and go all the way to the bottom making it very hard to spot them. First the Amazonian Apple snail grows to the size of a mans fist, which isn't all that bad because you would think they would be easy to spot.
