FISH SPECIES

African Fish

An African fish may be recorded in a rift lake, the Nile, the Congo basin, a seasonal wetland or a marine coast. These places have different connections, water conditions and histories. A continental label is useful for browsing, but it cannot by itself describe a species' ecology. Begin with a scientific name and the smallest geographic unit supported by the source. A lake record should not be converted into a claim about every African lake, and a captive specimen does not establish a wild locality.

Characteristics

Cichlid diversity in the African Great Lakes is a compelling reason to examine the habitat within a lake. A fish recorded among rocks may feed and breed differently from another using open water or sand. The word cichlid does not settle those details. FishBase describes varied feeding and parental-care patterns across the family. Identify the species and its lake before assigning a mouthbrooding mode, diet or social behavior to a photograph.

02 / LIFESTYLE

Lifestyle

African lungfishes are often used to illustrate air breathing and survival in challenging waters. FishBase's account of the marbled lungfish lists specific Nile and Congo-basin localities and describes air breathing with qualifications about conditions. Those details are more useful than a claim that all African fish breathe air or survive drought. An adaptation belongs to a named animal, and its field expression may depend on the environment and life stage.
