The long-nosed horned frog (Megophrys nasuta), also known as the Malayan horned frog or Malayan leaf frog is a species of frog restricted to the rainforest areas of southern Thailand and Peninsular Malaysia to Singapore, Sumatra, and Borneo. However, records from Thailand to the Sunda Shelf may apply to another, possibly unnamed species.
Malayan Leaf Frog Appearance
This species is a large frog that ranges from 100 to 120 mm in length. They are light brown to dark brown on the dorsal surface with various patterns and are well camouflaged against the forest floor. Throat is dark brown in color and spreads creamy yellow halfway along the ventral surface. The upper eyelids and muzzle are drawn in a long triangle, forming what looks like “horns”, giving them their common name.
There are two pairs of skin folds on the back of this species. One pair begins behind the eye and ends near the groin, the other begins at the corner of the eye and ends about halfway between the armpit and the groin. The back has large, randomly scattered nodules. The arms and legs have folds in the skin, speckled with cream and various shades of brown. The toes are slightly webbed and the fingers are not. The eardrum is not clear and the iris is yellowish brown.
Malayan Leaf Frog Camouflage
With triangular horn or leaf-like projections extending over each eye and its nose the frog could easily be mistaken for a dead leaf on the forest floor. They are light to dark brown on the dorsal surface with varying patterns and camouflage.
This species is actually shy in nature and will crouch down, motionless, when startled or disturbed. This is part of the frog’s strategy to avoid detection and for greater camouflage among the leaf litter.
Long-nosed horned frog habitat
The Malayan horned frog is found in flat to sloping rainforests from southern Thailand to Sumatra and Borneo. Living on land, this frog seems to be commonly seen near stream banks and other bodies of water. It has been found that juveniles often hide under rotting leaves during the day, while adults tend to hide under logs and large rocks.
Many researchers have commented on the difficulty of locating this species during the day, but note that it is quite the opposite in the evening. Why? It seems that while the Malayan Horned Frog is extremely mysterious during the day, the light from the flashlight easily reflects into the frog’s eyes at night, instantly revealing its location. Another indication of the stealthy frog’s location, especially during the breeding season, is the loud horn-like call when calling to a male.
What do Malayan Horned Frogs eat?
Malaysian Horned Frogs are capable of eating crickets of varying sizes their whole lives. This can be supplemented with dubia roaches, Silkworms and Horn worms. At Josh’s Frogs, we feed our Horned Frogs primarily crickets and dubia roaches.
