Description

provided by AmphibiaWeb articles
Females reach 27.4-31.38 mm and males reach 25-30 mm in Snout to Vent Length (SVL). Head width is equal to max body width, head wider than it is long (head width 35.4 -40% SVL). Snout rounded (when viewed dorsally or laterally). Eye-nostril distance is approximately 50-69 % the diameter of the eye. Loreal region not concave. Diameter of eye is equivalent to 29.2-37.5% head length. Supratympanic fold is thin. Tongue is equally wide as it is long. Humeral spine is externally visible in males. Length of tibia is approximately 40-58 % SVL. When hind limbs are adpressed anteriorly, the ankle reaches the tip of the snout, when forelimbs adpressed posteriorly, the knees only just reach the elbow. Dermal tubercles or folds of skin are absent from the tarsal. Internal metatarsal tubercle is elliptical. Males have spines on the rostral and lateral sides of their head. Belly and thighs with many small tubercles. Dorsally dark green. Hands, feet, belly light yellow. Axilla region with a greenish-blue coloration. Bones are green.

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Found on vegetation in rocky areas. Males call while perched on the sides of rocks. They defend these calling sites because that is also where females will lay their eggs. Females have been seen on plants near the rocks as well as on the rocks directly. When disturbed, males retreat and return a few minutes later as if nothing happened (even if the flashlight is still beaming down on the defending male). Sexual dimorphism in this species can be observed by the fact that the females are larger and lack the facial spines present in males. In their sister species, Centrolene acanthidiocephalum, the females have spines, but significantly smaller than the males’

""Centrolene" petrophilum"

provided by wikipedia EN

"Centrolene" petrophilum is a species of frog in the family Centrolenidae. Also called the Boyaca Giant Glass Frog.[2]

It is endemic to Colombia. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss. Possible causes for habitat loss: Deforestation/logging and Intensified agriculture or grazing (livestock ranching, and the cultivation of crops) and mining are the known main threats to this species.

Species Information:

  • Sexual dimorphism: Females have spines but they are significantly smaller than males spines. Females are also larger than males. Females reach 27.4–31.38 millimetres (1.079–1.235 in) and males reach 25–30 millimetres (0.98–1.18 in) in snout to vent length.
  • Locations/Habitat: Lives in tropical and subtropical moist broadleaf forests. Occurs in six geographical sites on the eastern flank of the northern portion of the Cordillera Oriental, Boyacá Department, Colombia. This species live on vegetation next to or above streams in a cloud forest, and can also be found in a secondary forest. It has an upper elevation limit of 2200 meters and a lower elevation limit of 1600 meters.
  • Mating: Females lay eggs on the sides of rocks in streams, and the larvae develop in the water. Males will defend and take care of the eggs.
  • Endangered as of August 2016
