Description :

Phyllobates bicolor is one of the largest poison dart frogs. Males can reach a length of 45–50 mm from snout to vent, while the slightly larger females reach 50–55 mm in length from snout to vent. P bicolor ranges in color from earthy orange to pure yellow in coloration, often with a blue or black tinge on their legs, hence their name. They are smaller and more slender than their close relative, Phyllobates terribilis, and can resemble juvenile or subadult P. terribilis frogs. They also bear a resemblance to D. leucomelas, particularly the "netted" color morph of D. leucomelas.

Toxicity :

While its toxicity is weaker than P. terribilis, P. bicolor is still a highly toxic animal, one of the few frogs confirmed to have caused human fatalities. Just 150 micrograms of its poison is enough to kill an adult human. This frog is often heated over a flame to make it "sweat" the liquid poison for hunting darts. The poison causes death by respiratory and muscular paralysis. Research is being conducted to determine medicinal uses for this batrachotoxin. As with all dart frogs, captive-raised individuals are not toxic; the animals require chemicals found only in their wild food sources, mainly insects. In captivity, these chemicals are not available to them from their food sources.
