Cryptobatrachus is a group of frogs in the family Hemiphractidae. They live in Colombia and Venezuela. People call them backpack frogs in English. The female frogs put their eggs on their backs they hatch.
Body
Cryptobatrachus look like treefrogs. Males are 27–52 mm (1.1–2.0 in) long from nose to rear end and females are 48–75 mm (1.9–3.0 in). Fingers have no webbing whereas the toes are webbed. The finger and toe tips bear disks that are larger on the former. They have sticky pads on some of their toes. The males frog does not have a vocal sac and scientists think these frogs do not ribbit.
Species
There are five species in the genus Cryptobatrachus:
- Cryptobatrachus boulengeri Ruthven, 1916
- Cryptobatrachus conditus Lynch, 2008
- Cryptobatrachus fuhrmanni (Peracca, 1914)
- Cryptobatrachus pedroruizi Lynch, 2008
- Cryptobatrachus ruthveni Lynch, 2008
AmphibiaWeb says that Cryptobatrachus nicefori is in this genus too, but Amphibian Species of the World says that species is in the hylid subfamily Cophomantinae and calls it "Hyla" nicefori.
Home
Cryptobatrachus live in forested slopes with water in the air in the mountains in northern Colombia and northeast Venezuela. Scientists have seen the frogs from 360–2,400 m (1,180–7,870 ft) above sea level. They are awake at night. They sit on low bushes or on rocks and cliffs near waterfalls
