aeI like your photos of Silurana tropicalisI would say it is one of my favorite African species. According to many researchers, this species is replacing X. leavis as a model lab organism. The reason is that S. tropicalis matures twice as fast as X. laevis and is less genetically complicated. By the way, frogs in the genus Silurana are more closely related to Pipa (Surinam toads) and Hymenochirus (dwarf clawed frogs) than to Xenopus.
