Key Facts
Meet the Watery Wanderers!
Imagine tiny homes that move! That's what freshwater snails are like. Most of them carry their cozy shell on their back, like a little backpack. They can be found in all sorts of watery places, from puddles that dry up to giant lakes and even fast-moving rivers. They are super important for keeping the water clean by munching on algae and other bits.
Shells, Gills, and Breathing Bubbles!
These little snails have cool ways to live underwater. Some have special parts called gills that help them breathe, just like fish! Others need to pop up to the surface for a breath of air, like a tiny submarine. Some super snails can do both! Their shells can be different shapes and sizes, some are round and some are pointy, and they help protect them from hungry critters.
What's on the Menu for a Snail?
Freshwater snails are mostly plant-eaters. They love to slurp up yummy algae that grows on rocks and plants, kind of like how you might eat your veggies! Some snails are also 'detritivores,' which means they eat tiny bits of dead plants and animals that sink to the bottom. They are like nature's little clean-up crew, making sure nothing goes to waste in their watery homes.
Tiny Homes, Big Adventures!
There are SO many different kinds of freshwater snails, more than you can count on your fingers and toes! They live all around the world, in almost every country. Even though they are small, they play a big role in their homes. They help other animals by being a food source and by cleaning up the water, making it a better place for everyone.
