Cryptobatrachus

Cryptobatrachus is a genus of frogs in the family Hemiphractidae. They are found in Colombia and Venezuela. They are also known as backpack frogs, as the females have the habit of carrying their egg clutch on their backs until the young hatch; this behavior also occurs in the related hemiphractid genera Hemiphractus and Stefania.

==Description== Cryptobatrachus have a treefrog-like habitus. Males measure and females in snout–vent length. Fingers have no webbing whereas the toes are webbed. The finger and toe tips bear disks that are larger on the former. Also adhesive pads are present on the penultimate subarticular tubercles on the fingers. Males lack vocal sac and these frogs appear not to vocalize.
