Lungfish

The lungfishes are a type of fish that can breathe air, and have limb-like appendages instead of fins.

Lungfish are generally believed to have evolved from other fish early, and their taxonomy is still in flux; some authors put all lungfishes in a subclass Dipnoi. However, there seems to be agreement that there are two orders.

Order Ceratodontiformes

• Family Ceratodontidae, genus Neoceratodus:
  • Australian lungfish Neoceratodus forsteri

Order Lepidosireniformes

• Family Lepidosirenidae, genus Lepidosiren:
  • South American lungfish Lepidosiren paradoxa

• Family Protopteridae, genus Protopterus:
  • Marbled lungfish Protopterus aethiopicus
  • East African lungfish Protopterus amphibius
  • African lungfish Protopterus annectens
  • Slender lungfish Protopterus dolloi
