Interesting facts

Even though they live in mud, their shells often host tiny algae or other creatures!

If a predator approaches, they can quickly pull their whole body inside their sturdy shell!

These snails are excellent underwater vacuum cleaners, tidying up the seafloor!

They lay their eggs in tiny capsules that look like miniature bumpy beads.

Special abilities

Threeline Mudsnail can detect food from a distance because it has powerful chemoreceptors that help them find decaying matter in murky water.

Threeline Mudsnail has a hard, spiral shell that helps them retreat completely inside for protection from predators and strong currents.

Threeline Mudsnail can cling tightly to surfaces because it has a strong muscular foot that helps them navigate diverse underwater terrains.

Threeline Mudsnail can rapidly consume decaying organisms because it has a specialized radula that helps them efficiently process detritus.
