Hemiphractus (known as horned (tree)frogs) is a genus of frogs in the family Hemiphractidae.[1][2] They are found in northern South America and Panama.[1]
Description
Hemiphractus are robust-bodied frogs.[3] The genus is characterized by a fleshy proboscis on terminus of snout and fleshy tubercles on eyelids, skull that is highly casqued with prominent lateral occipital processes projecting backwards, and fang-like maxillary and premaxillary teeth.[4]
Female frogs carry eggs openly on their back; the eggs adhere to the mother's back with gelatinous material. Eggs hatch as fully developed froglets.[5]
Ecology and behaviour
Hemiphractus are believed to be specialized predators of other frogs, and hence confined to areas with high density of frogs.[6] They can threat their predators by opening their mouth, exposing the colourful tongue.[7]
Species
There are six recognized species:[1]
- Hemiphractus bubalus (Jiménez de la Espada, 1871)
- Hemiphractus fasciatus Peters, 1862
- Hemiphractus helioi Sheil & Mendelson, 2001
- Hemiphractus johnsoni (Noble, 1917)
- Hemiphractus proboscideus (Jiménez de la Espada, 1871)
- Hemiphractus scutatus (Spix, 1824)
