Description: Slightly flattened head and body. Slippery-skinned with bulging eyes and long limbs. Greenish-brown with deep reddish mottling or patches. Natal Ghost Frog has yellow markings on a dark brown background. Belly granular white. Toes with T-shaped adhesive pads and extensive webbing. Pupils vertical.
Where found: Fast-flowing mountain streams, in forests.
Call: Clear, high-pitched ringing or whistling notes, audible above the rushing stream.
Reproduction: Eggs are laid in protected places next to mountain streams. Tadpoles are adapted to the fast-flowing water and cling to rocks with their teeth while eating the algae. Tadpoles live for two seasons and grow to 90 mm before they metamorphose.
Notes: The highly specialised tadpoles are able to climb vertical waterfalls using their teeth to grip onto the slippery rocks. Different species inhabit different isolated regions.
