Floscularia ringens is a species of rotifer belonging to the class Monogononta, which resides in a tube that it builds using many little circular pellets consisting of bacteria and small pieces of detritus.

[2] Floscularia ringens grows to around 1.5 millimeters long and resides in freshwater locations, where it makes its small tube by connecting to the bottom of the leaves of water lilies.

[1] After the corona develops the Floscularia ringens starts to eat through making currents, and it also begins to create its tube.
