Greater Swamp Frog

(Rana ingeri) (Kiew)

Description: This is a large heavy-bodied frog, with heavily muscled legs. It is similar to Rana leporina, except that the top and side of the snout do not form a sharp angle as in R. leporina, but are rounded. The eardrum is very distinct. The toes are fully webbed and have slightly swollen tips. The back has a few short ridges and the sides have a few scattered bumps. The upper eyelid is rough. The upper surfaces are reddish brown to dark brown, with indistinct darker markings. Unlike R. leporina, this species has no dark strips from the eye to the nostril. The chin and throat are heavily mottled with gray-brown. The chest and belly are grayish white with indistinct mottling.

Males: 75-132 mm.

Females: 70-127 mm.

Tadpole: The tadpole of this species looks very similar to those of R. leporina and ibanorum. It is oval, slender, and with a tail about twice the length of the body. The body is irregularly spotted and the tail is speckled with dark brown or black.

Habits and habitat: This species lives in both primary and disturbed forests, and may even be found in rubber plantations. It is often encountered in swampy areas and along muddy streams. Adults of this species are always found singly. Tadpoles live in quiet side pools of streams. Adults feed on large prey, including crabs, frogs, and even small snakes.

Call: Males have no vocal sacs and are not known to call.

Distribution: Brunei, Sabah, and Sarawak, not known outside of Borneo.
