The head is large and wide with snout that is rounded when viewed dorsally but sloped and truncated when viewed laterally. The color is green to pale green, and dorsal skin is granular. The males have a large humeral spine.[7] ReproductionIkakogi tayrona breed on vegetation alongside streams. Males call from the same or nearby leaves, night after night, sometimes engaging in male-male combats. Oviposition takes place on the same leaves where males have been calling some {{convert|0.5|-|2|m|abbr=on}} above the ground (higher oviposition sites are possible but difficult to observe). Only the females have been observed to attend egg clutches. Attendance is nearly continuous during the night, whereas during the day the female may temporarily leave the clutch. Experimental removal of attending females greatly increased mortality of the eggs.[6]Habitat and conservationIts natural habitats are sub-Andean forests and cloud forests where it occurs on vegetation near water. The elevational range is {{convert|980|–|1790|m|abbr=on}} above sea level. Part of the range is protected within the Sierra Nevada de Santa Marta National Natural Park and in the El Dorado Nature Reserve by Fundación ProAves. Outside the protected areas, it is threatened by habitat loss. Also pollution of water and fumigation of crops are threats.[1] References1. ^1 2 {{cite journal | author = IUCN SSC Amphibian Specialist Group | title = Ikakogi tayrona | journal = IUCN Red List of Threatened Species | volume= 2014 | page = e.T54941A60780944 | year = 2014 | doi = 10.2305/IUCN.UK.2014-3.RLTS.T54941A60780944.en }} {{Taxonbar|from=Q21216484}}{{DEFAULTSORT:Ikakogi Tayrona}}2. ^1 {{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Centrolenidae/Ikakogi |title=Ikakogi Guayasamin, Castroviejo-Fisher, Trueb, Ayarzagüena, Rada, and Vilà, 2009 |author=Frost, Darrel R. |year=2016 |work=Amphibian Species of the World: an Online Reference.
