Interesting Facts about the Castalia

The Castalia is a freshwater mussel. It is endemic to Brazil. The Castalia is a bivalve mollusk, which means it has a soft body that is enclosed within a hinged shell. The Castalia constantly pumps water to feed and breathe. It filters out the suspended particles in the water. This mussel attaches itself to rocks by threadlike filaments; these filaments are called byssal threads.

Did you know?

  • The Castalia is in the Phylum Mollusca and the Class Bivalvia.
  • Mussels filter as much as eight gallons of water per day through their internal filtration systems.
  • Since the Castalia constantly pumps water, it is vulnerable to water pollution.
  • Castalia move by extending their foot out of their shell and pulling themselves along.
  • The Castalia is in the Hyriidae family.
  • Castalia usually live in colonies.

Lesson plan note: Cut a large piece of butcher paper and lay it flat on the ground. Draw a picture of a large stream with rocks running across the paper. Use a blue marker to color the stream. Then, have each child draw Castalia mussels in the stream. They can use markers, crayons, or colored pencils to color their mussels. Hang the picture on your bulletin board when complete.
