(Arthroleptis krokosua)
These species are terrestrial breeding,with direct development (metamorphosis to froglets occurs within the egg).Many species in this genus are small,or very small,frogs with a minimum adult size of 15 mm (0.59 in) snout-vent length.The largest species (Arthroleptis nikeae and Arthroleptis tanneri) reach body lengths around 55 mm (2.2 in).It was hypothesized that small species evolved from larger ones,but in fact the opposite seems to be case.
