Lungfish

Lungfish are generally believed to have evolved away from regular 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

Lungfish[?] is also a musical band.
