Sarcohyla cyanomma

Sarcohyla cyanomma, also known as the blue-eyed aquatic treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico and only known from the northern slope of Cerro Pelón, in Sierra de Juárez in northern Oaxaca. It is feared that the species might be extinct.

Animal name origin

The specific name cyanomma is derived from the Greek words kyanos ("blue") and omma ("eye") and refers to the blue eyes of this species.

Appearance

Sarcohyla cyanomma is a large, robust frog. Adult males measure 52–56 mm (2.0–2.2 in) and females 52–65 mm (2.0–2.6 in) in snout–vent length. The tympanum is partly or completely concealed. The fingers have vestigial webbing whereas the toes are moderately webbed. The dorsum is uniform olive-green with few tiny, bright yellow spots; the olive-green fades to pale blue around vent and along outer edge of forearm and tarsus. The venter and chin are greenish-yellow, as are the outer toes and fingers. The ventral surfaces of limbs to the inner toes and fingers bright are yellow-orange. The iris is pale bluish-gray. Males have enlarged non-projecting prepollex (the "spikethumb") but not nuptial excrescences.
