Ferrissia californica Habitat
These freshwater limpets can live in many different kinds of water environments. You can find them in streams, rivers, lakes, and ponds. They often attach themselves to rocks, pieces of wood that have fallen into the water, aquatic plants, or even dead leaves at the bottom.

Ferrissia californica mainly eats tiny, single-celled algae called diatoms. These diatoms are a common food source for many small aquatic animals.
Life Cycle of Ferrissia californica
Ferrissia californica has an interesting way of reproducing. Each snail can fertilize its own eggs, meaning they don't need a partner to have babies. They lay very small eggs, about 0.6 mm in size. Each egg contains one tiny snail. These eggs usually hatch in about seven days. The young snails grow up quickly, becoming mature adults in about four to five weeks.
Ferrissia californica and Humans
You might sometimes find Ferrissia californica in the aquarium trade. People who keep fish tanks might accidentally get them. Because they can reproduce quickly and spread easily, they are sometimes seen as an "aquarium pest" by tank owners.
