HERE ARE 10 UPPER JAW BICHIRS
under the Polypterus genera, including the sole Erpetoichthys species:
• P. senegalus senegalus • P. delhezi • P. palmas palmas • P. palmas polli • P. palmas buettikoferi • P. weeksii • P. ornatipinnis • P. teugelsi • P. retropinnis • P. mokelembembe • Erpetoichthys calabaricus
Combining both lists gives you the 15 described Polypterus and the additional E. calabaricus species, for a total of 16 described Bichirs.
Among the undescribed Bichir species, Polypterus senegalus meridionalis is an Upper Jaw Bichir, but is said to be extinct. Among the undescribed Lower Jaw Bichirs, we have the following:
• Polypterus sp Koloton • Polypterus sp Koliba • Polypterus sp Dabola • Polypterus bichir katangae (may also be extinct)
While the undescribed species are oftentimes discussed and accepted in the Bichir keepers’ circle, they are still very much unaccepted in the scientific community. Technically, they are yet to be included in the official list of Polypterus species.
