KORSMAN CONSERVANCY
OTHER FAUNA
Reptiles, amphibians and arthropods form most of the other fauna.
Arthropods have an exoskeleton, a segmented body and jointed legs. They form the largest family of creatures and include insects, spiders, crustaceans and myriapods.

Amphibians
Four species are recorded: Guttural Toad (below L) Common Platanna (below R), Common Caco and Common River Frog.
The present status of Bullfrogs is not known, but they are threatened by reed encroachment and the long-term high water level.

Reptiles
