Ansonia spinulifer, also known as spiny slender toad or Kina Balu stream toad, is a species of true toad in the family Bufonidae. It is found in Sarawak and Sabah, northern Borneo (Malaysia), and presumably also in Kalimantan on the Indonesian part of the island.[2]

Description

Ansonia spinulifer males measure 30–40 mm (1.2–1.6 in) and females up to 45 mm (1.8 in) in snout–vent length.[3] Tympanum is visible.[4] Dorsum has big spinose warts and usually a light spot between the shoulders. The warts are large and have keratinized projections, hence the species name. Tadpoles have the typical sucker mouth of rheophilous Ansonia tadpoles.[3]

Habitat and conservation

Its natural habitats are lowland rainforests at elevations of 150–750 m (490–2,460 ft) asl. Adults range widely over the floor and herb stratum in areas of steep terrain, but breeding requires small, clear, rocky-bottomed streams.[1] Males call at night, sitting in low vegetation close to streams.[3] The tadpoles live in torrents; they cling to rocks and feed on lithophytes.[1]

Ansonia spinulifer is common in Sarawak,[3] but it seems not to adapt to habitat modification. It is threatened by habitat loss (deforestation and the associated siltation of streams; plantations).[1]
