A survey of animal kingdom presented a variety of excretory structures
(i) Invertebrate have simple tubular type of excretory organs
(ii) Vertebrate have complex tubular form called the kidney
(iii) Platyhelminthes (Flatworm planaria) Protonephridia of flame cells are excretory organs
(iv) Some Annelids and Cephalochordate Protonephridia concerned primarily osmoregulations
(v) Earthworm and Annelids Nephridia is the excretory organ
(vi) Insect Malpighian tubules are the excretory organs. Antennal glands or green glands performs the excretory functions in crustaceans like prawn
