Nilus curtus is a spider species in the family Pisauridae.[2] The species is commonly known as the spotted Nilus fish-eating spider.[3]
Distribution
[edit]Nilus curtus is widely distributed throughout Africa, including Egypt and Sub-Saharan Africa.[3]
In South Africa, the species has been sampled from six provinces: Eastern Cape, Free State, KwaZulu-Natal, Limpopo, Mpumalanga, and Western Cape.[3]
Habitat and ecology
[edit]These are free-running ground dwellers associated with fresh waters and known to catch small fish, tadpoles, and large aquatic invertebrates including insect nymphs or larvae.[3]
They can be found at fresh-water pools and have been sampled from the Fynbos, Forest, Grassland, and Savanna biomes at altitudes ranging from 15 to 1467 m.[3]
Sierwald reported on the predatory, copulatory, and parental behaviour of this widespread and commonly collected species in the Afrotropical Region.[3][2]
