It is found in southwestern Cameroon and in Equatorial Guinea, including the island of Bioko.[2] It is named for Ivan T. Sanderson, a British naturalist and explorer, and later on, author and television commentator.[2] HabitatPhrynobatrachus sandersoni live in the vicinity of streams in forest. They are only found in secondary habitats at higher elevations. It is a common species but it probably suffers from the loss of forest habitats.[1]DescriptionPhrynobatrachus sandersoni are small frogs: adults measure {{convert|21|-|26|mm|abbr=on}} in snout–vent length. They have a distinct tympanum. Tips of fingers and toes are dilated into large T-shaped discs; the toes have moderate webbing. Breeding males exhibit nuptial pads, lateral vocal folds, femoral glands and enlarged pseudo-teeth in the lower jaw.[2]ReproductionEggs are laid on leaves close to water, but not above water. Female frog may guard its egg clutch usually consisting of 12–17 eggs. The tadpole falls to the ground and develops on land. It has "semi-direct development": the tadpole relies on its yolk and does not eat; it lacks a fully developed alimentary canal.[1][2] References1. ^1 2 {{Cite journal | author = IUCN SSC Amphibian Specialist Group | title = Phrynobatrachus sandersoni | journal = The IUCN Red List of Threatened Species | volume = 2013 | page = e.T58152A18395748 | publisher = IUCN | date = 2013 | url = http://www.iucnredlist.org/details/58152/0 | doi = 10.2305/IUCN.UK.2013-2.RLTS.T58152A18395748.en | access-date = 11 January 2018}} [3]2. ^1 2 {{cite web |url=http://africanamphibians.myspecies.info/taxonomy/term/1604 |title=Phrynobatrachus sandersoni (Parker, 1935) |author=Zimkus, B. |year= |work=African Amphibians |accessdate=30 September 2015}} 3. ^1 2 {{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Phrynobatrachidae/Phrynobatrachus/Phrynobatrachus-sandersoni |title=Phrynobatrachus sandersoni (Parker, 1935) |author=Frost, Darrel R. |year=2018 |work=Amphibian Species of the World: an Online Reference.
