Anurans exhibit modes of fertilization which place them in a category between true aquatic and true internal fertilizers. Their fertilization environments range from aquatic to terrestrial. This study descriptionbes the sperm structure and ultrastructure of representatives of two groups of anurans. The ranines occupy fertilization environments within bodies of water (aquatic) and the African rhacophorids in a foam nest on a tree branch (terrestrial).
