Philodina rosea is a common bdelloid rotifer found in bird baths and other small waters. Many of these bdelloid rotifers lack sexual reproduction. It has the typical crown of cilia (corona) that gave rotifers their name. Near the two eyespots lies the mastax, a jaw-like device for grinding food particles.
