Protonephridia, also known as flame cells, are excretory structures found in rotifers, certain annelids, the cephalochordate Amphioxus, and Platyhelminthes (flatworms, such as Planaria).
Earthworms and other annelids have tubular excretory organs called nephridia.
The excretory structures of the majority of insects, including cockroaches, are called Malpighian tubules.
In crustaceans such as prawns, the excretory function is carried out by the green or antennal glands.
