This lively shelled rotifer has a double keel and several spikes ornamenting its rear end.
Philodina is one of the most common of the freshwater rotifers. It is a
large, lush, flexible rotifer with a double corona. This was one of several
lined up along a strand of algae. All members of this genus are female.
No one has ever found a male or hermaphrodite Philodina, making it one
of the most complex animals to always reproduce by parthenogenesis.
