Native vertebrates include the De Witte's clawed frog, Lake Victoria clawed frog (""bunyoniensis"" form), African clawless otter and spotted-necked otter, but only the first frog is still common in the lake. Four endemic species of "Caridina" shrimp are found in the lake; there are indications that they might also occur in Lake Mutanda. Originally, there were no fish or crayfish in the lake, but the catfish "Clarias liocephalus", Nile tilapia, Singida tilapia, haplochromine ciclids of Lake Victoria origin and red swamp crayfish have been introduced.
