Heleophryne hewitti |
The Heleophrynidae, is a family of order Anura, commonly known as ghost frogs. The family consists of a single genus, Heleophryne, and six species. These frogs live in swift-moving streams found in the mountainous areas in South Africa. The common name of "ghost frogs" may have been coined because of their occurrence in Skeleton Gorge.
The ghost frogs habit mountain streams, within their distribution, and have morphological adaptation suited to surviving on the rocks around these streams. They are medium sized frogs, reaching a length of 6 centimetres, with flat bodies. They have very large toe discs in comparison to their size, which helps to cling onto rocks. The mouthparts of the tadpoles are modified into a sucking disc, to allow them to cling to substrates, and remain still, while they are feeding.
[edit] Taxonomy
The ghost frogs are closely related to the Sooglossidae family, which inhabit Seychelles, an island close to the African coast. They may also be closely related to the Australian Myobatrachids.
