Limnonectes palavanensis (common names: smooth guardian frog, Palawan wart frog) is a species of frog in the Dicroglossidae family. It is found in the Palawan Island (the Philippines, its type locality) and in Borneo (Brunei, Indonesia, Malaysia).[2][3] The species shows paternal care,[1][3] a relatively rare trait in frogs.[4]


Male Limnonectes palavanensis grow to about 30 mm (1.2 in) and females to about 40 mm (1.6 in) in snout–vent length. There is a V-shaped ridge between the shoulders, and a sharp interorbital band that separates the anterior part of the head from differently colorer back. Juveniles have a medial vertebral stripe that in some populations persists in adults too.[3]

The tadpole is moderately flat (dorsoventrally compressed). The tail is twice the length of the body. The tail fin is low and ends in a pointed tip.[3]


The male of this species guard the tadpoles that hatch from the eggs laid on the ground. The male then carries the tadpoles on its back to water.[1][3]

Habitat and conservation[edit]

Its natural habitats are lower montane and lowland forests. The tadpoles develop in small rain pools[1] and quiet sections of small, slow moving streams.[3]

The habitat of this species is mostly well protected, although it can potentially be impacted by habitat loss.[1] It occurs in the Crocker Range National Park.[5]
