Emerald and gold: Two new precious-eyed endemic tree frog species from Taiwan

Two endemic tree frog species, not recognised by science until now, have been identified in broadleaf forests in the island country of Taiwan. Unlike their siblings from mainland China and Southern Asia, they demonstrate reproductive behaviour, characterised with egg-eating (oophagous) tadpole embryos feeding on eggs, while still inside the mother's womb. What told them apart initially, however, were their gemstone-coloured eyes. The research team, led by Dr. Shu-Ping Wu, University of Taipei, have their study published in the open-access journal ZooKeys.

One of the new species, whose scientific name, K. berylliniris, translates from Latin to 'green-coloured iris', has been found to dwell among the leaves of moist forests in eastern Taiwan. It is a slender-bodied amphibian with the females slightly bigger than the males, measuring an average length of 41 mm versus 35 mm, respectively. Matching its emerald eyes is its body, which can be either dark green in colour, or deep tan. It is only the belly and the throat that, in contrast, are white and sometimes faintly speckled. On the other hand, its tadpoles vary from heavily dark brown to black.
