The long-nosed horned frog ( Megophrys nasuta ) is a Froschlurch - type from the genus Megophrys .

features

The pointed toad frog is a very stocky, medium-sized to large frog. The legs are short and slender. The width of the head is half the length of the head and torso . At the front edge of the eyelids there is a very large, triangular and pointed process. A similar pointed extension is located at the tip of the snout. There are two pairs of long and narrow folds of skin on the back. The color varies from a light clay brown to a reddish brown. There may be one or two dark spots on the back. There is usually a broad, dark mark under the eye on the side of the head.

Males reach a length of 70 to 105 millimeters, females are slightly larger with 90 to 125 millimeters.

Occurrence

The large range of the species extends from Yala in the south of Thailand over the Malay Peninsula , Singapore, Tioman , Bintan , the Natuna Islands and Sumatra to Borneo. It lives in the rainforests from the plains to altitudes of 1000 meters.

Way of life

When a storm approaches, the male toad frogs utter calls that sound like a loud horn. The mating takes place in rivers with low to moderate currents. The tadpoles live on the shallow areas of the water and often hide between root mats hanging in the water.

Danger

The species is classified as not endangered by the International Union for Conservation of Nature and Natural Resources (IUCN). The stock is considered stable. The destruction and fragmentation of their habitat represents a threat. Furthermore, it is collected for the national and international pet trade, which could affect local populations.
