Centrolene savagei is a species of frog in the Centrolenidae family that inhabits western Colombia on the Cordillera Occidental and Cordillera Central.[2] Its common name is Savage's Cochran frog.[3] Its natural habitat is sub-Andean forest, but it can also occur in secondary forests. It is currently listed as "vulnerable" on the IUCN Redlist because its distribution is fragmented and relatively limited in area, and its habitat is lost to agriculture (crops and livestock) and pollution.[1]

Description

Centrolene savagei is a small glassfrog: adult females measure 23–24 mm (0.91–0.94 in) in snout–vent length and adult males 20–23 mm (0.79–0.91 in) in snout–vent length,[4] sometimes even 24 mm (0.94 in).[5] The species has a number of defenses such as foul-smelling skin secretions and a variety of defensive postures and behaviors.[6]

Reproduction

The advertisement call of Centrolene savagei males consists of 1–3 "peep" notes, each about 17 milliseconds in length (range 10–22 ms), and separated by silent intervals 302–442 ms in duration.[5] Larger males have lower-pitch calls and higher mating success. Females lay 15–27 cream-coloured eggs on leaves; males can guard the eggs for 24 hours or more.[7]

Tadpoles grow up to 33 mm (1.3 in) in length.[5]
