The thorny tree frog (Gracixalus lumarius, photo above by Jodi J. L. Rowley, Duong Thi Thuy Le, Vinh Quang Dau, Huy Duc Hoang, and Trung Tien Cao) was recently discovered in Vietnam at an altitude of around 2,000 metres on the slopes of Ngọc Linh and nearby mountains.
These fascinating little frogs breed in water-filled tree hollows (phytotelmata), rather than in ponds or streams. They are about 4 cm long, and coloured pink and yellow. Curiously, the males are covered in sharp thorny spines. For more information, see this report from the Australian Museum, and also the published paper by Jodi Rowley et al.
