Boulengerula niedeni Müller, Measey, Loader, and Malonza, 2005
As this species occupies such a small area on Sagalla, and due to the problems with the spreading eucalyptus and ongoing soil erosion, this species is considered to be Critically Endangered (Text from Measey et al. 2009, © SANBI).
The young probably feed off the skin of the mother, before becoming independent. The Sagalla caecilian feeds on earthworms and termites as well as other small invertebrates that live in the soil (Text from Measey et al. 2009, © SANBI).
