Habitat & Fossil Locality

Low- to mid-elevation forests in Taiwan and Japan's Yaeyama Islands (Iriomote and Ishigaki), breeding in pools inside bamboo stumps and tree holes

💡 Everyday Comparisons for Size, Mass & Speed

💡 Its body length of 5 cm is about twice the diameter of a Korean 500-won coin (26.5 mm) (Comparison).
💡 Besides bamboo stumps and tree holes, cases of egg-laying in water-filled metal poles, rock crevices, and even toilet tanks and washing-machine drainpipes have been observed in Taiwan.
💡 It breeds from March to September in western Taiwan and from September to March of the following year in eastern Taiwan.

📖 1. Overview

Eiffinger's Treefrog is a small treefrog that lays eggs in water collected inside bamboo stumps or tree holes, recorded in Taiwan and Japan's Yaeyama Islands. It is assessed as Least Concern (LC, 2022 assessment) on the IUCN Red List.

🦴 2. Anatomy & Morphology

Its body length is about 3–5 cm, and its color shifts from light brown to green. Its skin has many granular tubercles, its back bears an X- or H-shaped dark brown mark, and both sexes have a well-developed reddish bump (inner metacarpal tubercle) below the thumb.

🔍 3. Ecology & Behavior

Males call from inside water-filled bamboo stumps or tree holes, and after mating and egg-laying the male stays by the eggs to keep them from drying out or growing mold. Females return while the tadpoles are growing to lay unfertilized eggs as food, making it the only one of Taiwan's 33 frog species in which both parents care for the young.
