Retodus (SciiFii)

Note the three small skin parasitic lampreys on its body, something a healthy African greater lungfish doesn't have.

The African greater lungfish (Retodus africanus) is a species of prehistoric lungfish that originally lived in Cretaceous-aged freshwater strata of Africa as an extinct species of Retodus and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern lakes and rivers across Africa to help boost biodiversity. The African greater lungfish is normally around 6.3 feet (1.9 meters) long when fully grown, but some individuals have grown to be about 6.6 feet (2 meters) long. The African greater lungfish is reputed to be sluggish and inactive, but it is capable of rapid escape movements with the use of its strong tail. It is usually quiet and unresponsive by day, becoming more active in the late afternoon and evening. A distinctive characteristic of the African greater lungfish is the presence of a single dorsal lung, used to supplement the oxygen supply through the gills. During times of excessive activity, drought, or high temperatures (when water becomes deoxygenated), or when prevailing conditions inhibit normal functioning of the gills, the lungfish can rise to the surface and swallow air into its lung. More frequent air breathing is correlated with periods of greater activity at night when it uses the lung as a supplementary organ of respiration. The African greater lungfish spawns and completes its entire lifecycle in freshwater systems. The age of first breeding is estimated to be 17 years for males and 22 years for females. After an elaborate courtship, the lungfish spawn in pairs, depositing large adhesive eggs amongst aquatic plants. They spawn from August until November, before the spring rains, in flowing streams that are at least a metre deep. The African greater lungfish is primarily nocturnal, and is essentially carnivorous. In captivity, it will feed on frogs, earthworms, pieces of meat, and pelleted food. In the wild, its prey includes frogs, tadpoles, fishes, a variety of invertebrates, and plant material. The conservation status of the African greater lungfish is Least Concern due to successful conservation efforts and the African greater lungfish's wide range.
