Rana longicrus, commonly known as the Taipa frog or long-legged brown frog, is a species of frog in the Ranidae family, endemic to northern and central Taiwan.[2] Its natural habitats are subtropical broadleaf forests as well as cultivated fields below 1000 m elevation. Breeding takes place in marshes, pools, and ponds. It is threatened by habitat loss, in particular due to infrastructure development, but also pollution.[1]

Description
Rana longicrus is a slender-bodied frog with relatively long legs. Males measure 42–56 mm (1.7–2.2 in) and females 58–65 mm (2.3–2.6 in) in snout–vent length.[3]
Reproduction
The breeding season in Aoti, northern Taiwan, is from November to March. The smallest mature male measured 33 mm (1.3 in) SVL and smallest gravid female 32 mm (1.3 in) SVL. Both sexes appear to reach this size by the end of their first year. Peak breeding occurred in December but is probably influenced by rain. Egg clutches of 600-2,000 eggs are laid in water. Metamorphosis occurs after about two months. However, survival to metamorphosis is low because of disturbance by human activities (plowing of ricefields) and by the desiccation.[4]
Diet
Rana longicrus feed primarily on arachnids and insect larvae and adults (often ants or beetles). In winter when they spend more time near water also crustaceans are eaten.[4]
