Kurixalus eiffingeri is a small and robust frog. The forelimb and hindlimb webbing is not well developed. The skin on the back of this species has tubercles and ridges. This species has 3-6 vomerine teeth. The mean snout to vent length for males is 34 mm (range 31-35) and for females it is 37 mm (range 36-40). In males, the nuptial pads are yellow and are without asperities. There is a pair of slit-like vocal openings. The species also has no dorsolateral fold, but the supratympanic fold is prominent (Maeda and Matsui 1990).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Japan, Taiwan
This species is found in both Taiwan and Japan, specifically on Ishigakijima and Iriomotejima Islands in Japan. The natural habitat is mountainous forests, especially of bamboo (Maeda and Matsui 1990).
Life History, Abundance, Activity, and Special Behaviors
Males of the Eiffinger's Tree Frog call from bamboo stumps filled with rain water (phytotelmata) to attract females during the breeding season (February to August). The females lay eggs above the waterline on the walls of the tree holes or stumps to be fertilized. Male frogs may guard egg sites for up to 2 weeks (ca. 10-14 days) until they hatch. Tadpoles, when hatched, will drop into the water body where they grow and develop (Lin and Kam 2008).
Selection of egg deposition sites are governed by water depths among other factors but clearly males are selective, especially given the amount of parental care required of both males and females (Lin and Kam 2008).
Tadpoles are obligate oophages, fed by female frogs which lay unfertilized eggs into the water for the tadpoles to eat (Lin and Kam 2008).
The mating call has notes that last 0.8 seconds with a frequency of 2.7 kHz (Maeda and Matsui 1990).
