West African Lungfish, Protopterus Annectens
2012-12-25 12:16:41

West African Lungfish thrive in fresh water in the West African countries of Senegal, Niger, Gambia, Volta and Chad basins, where the water temp ranges from 77 to 86 degrees. They also can be found in tributaries of the Chari River in Western Sudan. It is eel-like in looks with a long slender body containing 34 - 37 pairs of ribs. The body can be 9 - 15 times the length of its head with small eyes and a prominent snout. The pectoral fins (fins on each side closest to the head) are fringed...

Marbled Lungfish, Protopterus Aethiopicus
2012-12-25 12:06:57

The marbled lungfish is found mainly in the Nile river, in the northeastern continent of Africa. It also is found in such lakes as the Albert, Edward, Tanganyika, Victoria, Nabugabo, No and Kyoga, all centrally located in Africa at the southern end of the Nile. They live in the shallow areas of these lakes, streams, rivers, and swamps. During the dry season, many of the areas will dry up and when this occurs the marbled lungfish will bury themselves in the mud leaving just a small opening...

The Queensland lungfish, Neoceratodus forsteri, also known as Burnett salmon and Barramunda, is the sole member of the family Ceratodontidae, and one of the only six lungfish species that remain. Olive or dull brown in color, it grows to about 59.06 in (150 cm) in length, more commonly 39.37 (100 cm). It is native to the Burnett and Mary River systems of south-east Queensland, but has been introduced into other nearby rivers, including the Brisbane River. It prefers still or slow-flowing...
