Dendrobates auratus avoids predation through their aposematic coloration and extremely toxic skin secretions. Anti-predator Adaptations; aposematic; Ecosystem Roles. Poison dart frogs are important predators of small invertebrates. Economic Importance for Humans: Positive
The green and black poison dart frog is brightly colored as a warning to predators that they are poisonous and harmful if consumed. Across the body they are colored with a blotched pattern of black and green or light blue.
Identification: Adults are brilliantly marked with contrasting green or blue colored bands and spots on a black or brown background (several color morphs exist). These small frogs are about 25-60 mm long as adults, and the all black tadpoles range from around 22 mm to as large as 45 mm.
The poison in their glands comes from the ants they ingest. Their bright colors are warning for would-be predators of their poison. Size: Dendrobates auratus are considered large in size, varying from 1 to more than 1.6 inches (2.5- 4.2 cm) in length; females are slighter larger.
These frogs have poison glands on the surface of their body, and they capture prey using their sticky, retractable tongues and keen eyesight. Their bright colors are believed to discourage predators, and bold contrasting patterns may warn predators who have no color vision.
The green-and-black poison dart frog (Dendrobates auratus), also known as the green-and-black poison arrow frog and green poison frog (among others), is a brightly colored member of the order Anura native to Central America and northwestern parts of South America.
