Description

Males grow to 37 mm (1.5 in) and females 43 mm (1.7 in) in snout–vent length. Dorsum is warty and chocolate brown to almost black and has many small orange or golden spots. There is no vocal sac; the males appear to be mute.[5]

Habitat and conservation

The natural habitats of Callixalus pictus are high-altitude forests, especially bamboo forests, above 2,100 m (6,900 ft) asl but more commonly only above 2,400 m (7,900 ft). During the day time they hide in broken bamboo stumps or between the bark and the moss covering tree trunks.[1][5]

Callixalus pictus is threatened by habitat loss caused by agriculture, livestock farming, wood extraction, and expanding human settlements.[1]

gollark: Also, I think we have more rules than that which are useful.
gollark: It's not like illegal things are automatically bad.
