Other biodiversity Little information is available. The ungulate Tragelaphus spekii (LR/nt) occurs but is uncommon, and the snake Python sebae has been recorded. Like other wetlands around the shores of Lake Victoria, Kusa is probably an important refuge for a number of the lake’s endemic haplochromine fish species.
