Invasive species

Giant African land snail (Achatina fulica) This the worlds largest land snail, measuring up to 8 inches in length! They are native to Africa, but are a invasive species in south Florida. They are edible, but have to be boiled first. The animals is usually dark brown and sometimes white or yellow. Their shell varies in color, but is usually black, brown, and sometimes with tints of red. The rarer ones have a light yellow color, and a yellow color of their body.

Faucet snail (Bithynia tentaculata) This is a very small species, as it doesn't get bigger than an inch, but don't get fooled... This snail is doing lots of damage to the Great lakes habitats. It can be found in rocky shorelines. The shell, is yellow, brown, or white, while the animal is usually cream, black, or yellow. Unlike other freshwater species, this snail has a operculum (trapdoor) attached to its foot to protect it.

New Zealand mud snail (Potamopyrgus antipodarum) A tiny little mud snail that doesn't get larger than 7 millimeters in height wont do much damage right? Its actually doing a LOT of damage to rivers and ponds in Michigan, as its damaging the ecosystem. The bad part is, that its re-producing really fast, which makes these snails really hard to get rid of. Here is a way to not spread these pests: If you are wading in water in ponds, or rivers, check your boots for them, as these little hitchhikers can easily attach to them. There are two main color forms of this snails shell, orange, and black. The color of the snail itself is usually gray, or black. Don't confuse these with Glossy pillar snails, as they may appear similar.
