Dendrobates auratus can be identified by their calligraphic brillant green markings on a black background on their dorsal side (Caldwell and Summers 2003). Ventrally, they are marbled or spotted with yellow, blue, or green on dark background (Guyer and Donnelly 2005). Among populations there are variation in both hue (ranging from white to blue-green) and pattern (from thick stripes to dots) (Caldwell and Summers 2003). Dendrobates auratus has a smooth upper surface with a head that is relatively long. The snout truncates to slightly rounded (Savage 2002). Dendrobates auratus is the largest poison-dart frog in Costa Rica, with adult females ranging from 27.0-42.0 mm and adult males ranging from 25.0-39.5 mm (Leenders 2001).

This species can be found on the Caribbean slopes from southern Nicaragua to extreme eastern Panama, and on the Pacific slopes from the Osa Peninsula, Costa Rica to Colombia (Guyer and Donnelly 2005). It lives in lowlands, primarily rainforest (Caldwell and Summers 2003). It is a shy species, found deep in the forest interior (Leenders 2001).

Life History, Abundance, Activity, and Special Behaviors
These frogs forage during the day (Guyer and Donnelly 2005). They move by a series of hops, stopping briefly and hopping again when disturbed. They are excellent climbers with individuals climbing to 45 m above the ground (Savage 2002).

Males are territorial at high population densities but may not be at low populaton densities (Caldwell and Summers 2003). The male call is a high-pitched, insect-like buzz sounding like "cheez-cheez-cheez" (Leenders 2001). The call averages 3.5 kHz in frequency, and can last from two to four seconds followed by a five-second pause (Savage 2002). Males can mate with many females and care for offspring of different females simultaneously (Caldwell and Summers 2003). Females court the males and wrestle other females and chase them from their territories (Savage 2002). This behavior increases male reproductive success but puts survival success of offspring in jeopardy, since females do not defend their territories (Caldwell and Summers 2003). A single male can mate with up to six females (Savage 2002). After being selected by the females, the males then lead the females to the nest site made from leaf litter and the females lay four to six eggs there (Guyer and Donnelly 2005). The male visits the eggs periodically over the incubation period to shed water, remove fungus, and rotate the eggs. After the eggs hatch, the tadpoles crawl up on the male's back (Savage 2002). The male then transports the tadpoles to small pools of water, usually found in tree holes (Caldwell and Summers 2003). If some eggs hatch earlier than others, the tadpoles that are born first may practice cannibalism by eating the smaller tadpoles.

The tadpoles' diet consist of algae, detritus, protozoans, insect larvae, and each other (Leenders 2001). Tadpoles are moderate-sized and can reach 30 mm (Savage, 2002). The adults' diets consist mainly of tiny ants and mites but they also prey on beetles, flies, and springtails (Caldwell and Summers 2003). They are known to have a life-span of eight years in captivity but it is much lower in the wild (Leenders 2001).

Trends and Threats
This species is not threatened (Caldwell and Summers 2003).

Relation to Humans
This species is popular in the pet trade due to its bright colors (Leenders 2001).

Birds and mammals are well-known for their behavioral flexibility and learning aptitudes, but these traits are not as well-characterized in amphibians. Liu et al. (2016) investigated these traits in the poison frog Dendrobates auratus, a species with complex reproductive strategies that may favor highly flexible forms of learning. Experiments on serial reversal learning using a two-sided maze with distal visual cues revealed that the frogs could learn to identify the correct exit. Probe trials in which visual cues were switched demonstrated that the frogs relied on these cues. Serial reversals demonstrated that the frogs learned to learn more rapidly across trials, employing rule-based strategies to solve the maze with increasing rapidity, thus demonstrating high levels of behavioral flexibility and learning ability in an amphibian (written by Kyle Summers).

Amphibian genomes can be extraordinarily large, making it difficult to connect the genotype to the phenotype using large-scale genome-sequencing methods. One approach to this challenge is to take a transcriptomic approach, focusing on differential gene expression across different phenotypes in specific tissues. Stuckert et al. (2019) take this approach to investigate differential gene expression across distinct color pattern morphs in the green and black poison frog (Dendrobates auratus). These morphs vary in both background color (brown to black) and foreground (green to blue). They sequenced transcripts from skin tissue taken from tadpoles just reaching metamorphosis, an active period for pigment deposition and skin color development. A number of candidate color pattern genes were found to be differentially expressed between morphs, including genes involved in melanin production and melanosome development in basal skin layers (e.g. the tyrosinase-related protein 1, which catalyzes several key steps in melanogenesis, and affects dark coloration in a variety of vertebrates), genes involved in the development of iridophores (middle layer organelles containing reflective structures associated with blue-green coloration), and genes involved in yellow, orange and red pigment production in xanthophores (e.g. genes in pteridine pigment production pathways). These results will begin to provide insights into the genetic underpinnings of color variation in the brightly colored Neotropical poison frogs (Written by Kyle Summers).
