Cryptobatrachus fuhrmanni

Cryptobatrachus fuhrmanni (common name: Fuhrmann's backpack frog) is a species of frog in the family Hemiphractidae. It is endemic to Colombia and occurs on all three Andean cordilleras: it is found on the eastern slope of the Cordillera Occidental, northern and eastern flanks of the Cordillera Central, and the western slope of the Cordillera Oriental.[2][3][4] The specific name fuhrmanni honors Otto Fuhrmann, Swiss zoologist and helminthologist.[5]

Description

Adult males measure 28–52 mm (1.1–2.0 in) and adult females 51–73 mm (2.0–2.9 in) in snout–vent length. The snout is short. The tympanum is small and not sexually dimorphic. The dorsolateral folds are thin. The skin on the dorsum is finely granular with scattered larger warts. The fingers have no webbing. The finger and toe tips bear expanded disks. Subarticular adhesive pads are present.[3]

Female frogs carry the eggs on their back. The eggs have direct development, hatching as froglets[1] (i.e., there is no free-living larval stage[6]).

Habitat and conservation

Cryptobatrachus fuhrmanni is a common species of frog found on rocks in fast-flowing mountain streams in transition and montane forest[1] at elevations of 380–2,050 m (1,250–6,730 ft) above sea level.[3][4] Cryptobatrachus fuhrmanni can be threatened by habitat loss caused by agriculture and logging, but this species tolerates some habitat perturbation. It is present in the Reserva Regional Bosque de Florencia in Caldas.[1]
