[4] A. torrentis contains multiple characteristics that distinguish it from other members of the Amolops genus that also exist in China and southeast Asia.

[5] A. torrentis also has a distinct tympanum edge and a tibio-tarsal articulation reaching beyond the snout when the back limbs are adpressed.

[6] Individuals of this species also have a distinct glandular ridge (also known as a dorsolateral fold of skin) under the tarsus and smooth bumps on the back, along with a circummarginal groove at the tip of the first finger.

[7][8] Males of the species also possess a pair of subgular vocal sacs that are of white color.

A. torrentis has sexual size dimorphism, with females of the species tending to be larger than males of the species (adult females have snout-ventral lengths of less than 42 mm, while adult males have snout-ventral lengths of less than 35 mm).

[7] A. torrentis has only been found on Hainan island in China, in locations that range from 80 to 1000 meters in elevation.

[1] They are called torrent frogs because of their proximity to fast-flowing water and the background noise this presents.

[11] During the day, individuals of this species usually crouch on rocks near the stream rapids or on stone walls near the waterfalls.

[1] At night, individuals of A. torrentis can be found on rocks near the streams or on leaves of nearby shrubbery and weeds.

[17] Bradykinin is a powerful endothelium-dependent vasodilator that induces a drop in blood pressure, and the contraction of the bronchi and smooth muscles in the ileum.

[17] Isolated BRPs from A. torrentis have been shown to have a contractive effect on the smooth muscle of rat ileum in the laboratory setting.

[18] These midges are attracted to the acoustic signal given by male members of A. torrentis, which results in limb movements to defend against these parasites.

Nematodes from the family Acuariidae have been found as stomach cysts in museum samples from this species.

[1] Previously, it had been a concern that the construction of hydroelectric plants in Hainan would pose a threat to A. torrentis.

To combat the threat of habitat loss, A. torrentis is present in several protected areas in Hainan, including nature reserves and forest parks.
