AbstractThe speed of larval development of the South African bullfrog, Pyxicephalus adspersus, is exceptional among living frogs. Embryonic development, larval phase, and metamorphosis can be completed in 17 days at a temperature of 29C. The metamorphosis only takes 5 days. The present study shows that, despite the unusually short larval phase in P. adspersus, the state of skeletal differentiation...

This technique allowed a detailed examination and presentation of internal features of a representative of the suborder Myxophaga, which is characterized by the very small size of the immature stages and adults. Larval character states of H. natans were compared with features found in...
