Protopterus aethiopicus |
The African lungfish are the genus Protopterus and constitute the four species of lungfish found in Africa. Protopterus is the sole genus in the family Protopteridae.
The four recognised species are:
- Protopterus aethiopicus (Heckel, 1851) - Marbled Lungfish
- Protopterus amphibius (Peters, 1844) - East African Lungfish
- Protopterus annectens (Owen, 1839) - African Lungfish
- Protopterus dolloi (Boulenger, 1900) - Slender Lungfish
Protopterus aethiopicus is divided into three subspecies:
- Protopterus aethiopicus aethiopicus
- Protopterus aethiopicus congicus
- Protopterus aethiopicus mesmaekersi
Protopterus annectens is divided into two subspecies:
- Protopterus annectens annectens
- Protopterus annectens brieni
The African lungfish are obligatory air breathers. They generally inhabit shallow waters such as swamps and marshes, however they also found in larger lakes such as Lake Victoria. The African mudfish, or lungfish, can live out of water for many months in its burrow of hardened mud beneath a dried-up streambed. Native Africans have been found to dig it up, burrow and all, and store it for later use when they want fresh fish to eat. These fish have also been carried in their mud burrows for exhibition in the United States. They have a rather snake-like appearance and a strong taste. Kees et al., 2002 mentions that the taste is such that it "is locally either highly appreciated or strongly disliked." As technology advancements such as longlines and gillnets have been increasingly applied in the Lake over the past fifty years, it is believed that the lungfish populations there are decreasing.
