Asian Horned Frog; Asian Spadefoot Toad, Javan Horned Frog

Megophrys montana tadpoles have a funnel-shaped mouth, with turned-up and laterally expanded lips, allowing feeding at the surface of the water (Iskandar, 1998). The tail is elongated, with a rounded tip (Iskandar, 1998). The larval body and tail are brown (Lathrop, 2003).
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
This frog lives in leaf litter and remains immobile unless touched or molested (Iskandar, 1998). Frogs in the genus Megophrys rely on camouflage for defense; they move by short hops, since the combination of large, wide heads and bodies and short, slender legs hampers long jumps (Inger and Stuebing, 2005) and makes them rather clumsy (Wogan, pers. comm.).
During the mating season, Megophrys montana males make a single loud "kang" as their mating call, particularly when there is a full moon (Iskandar, 1998). Breeding behavior has not yet been described but is assumed to be similar to a related species, Megophrys nasuta. In Megophrys nasuta, and presumably also Megophrys montana, adults move from the forest to the edges of streams in order to breed (Inger and Stuebing, 2005). Megophrys montana eggs are colorless (Iskandar, 1998).
