Hylarana (Pulchrana) baramica inhabits alluvial and peat swamp forests in lowland regions, particularly in coastal areas. However, it can also be found further inland, for example at Mulu National Park in Sarawak.

This is a medium-sized species, with males reaching approximately 45 mm in snout-vent length and females up to 75 mm. The head is relatively broad, and the eyes are large. The tympanum (eardrum) is visible, usually dark with a lighter center. The fingers and toes are elongated, with slightly expanded tips. The subarticular tubercles under the fingers and toes are prominent.

Dorsally, this frog is mottled brown, transitioning to a lighter, sometimes yellowish, mottled coloration along the flanks. Its coloration is darker during the day than at night. The lips are conspicuously marked with dark bars and cream-colored spaces between them. The hind limbs feature cross-bars. The underside is whitish with irregular darker markings. The skin texture is granular, with scattered bumps and small tubercles. In large females, warts may form a dorsolateral line running from behind the eardrum toward the vent.

Hylarana baramica is agile and always on its toes, ready to make a big jump. Males call from vegetation 1–3 meters high. Their call is loud—a rapid series of notes with increasing intensity. A novice naturalist might confuse this species with Hylarana glandulosa. However, the latter is noticeably larger and features distinctive flat, round bumps along its flanks.

Despite the species' relative abundance in the area, its tadpole stage remains undescribed by science. Our prediction is, that the ecology of its larvae and larval morphology are most likely similar to those of the tadpoles of H. luctuosa. At Mulu National Park, breeding activities of the two species overlap in some areas of the alluvial forest.
