Anuran reproductive strategies: 1) rhacophorids create an arboreal foam nest; 2) Leptodactylus spp. create an aquatic foam nest; 3) a centrolenid with his clutch on the underside of a leaf, usually over a stream; 4) Eleutherodactylus creates a terrestrial clutch; 5) Bufo lays eggs in strings, one from each oviduct; 6) Rana lays a single, massive, aquatic clutch.
