Sporting a flashy pattern of lavender on black, this newfound species of toad is among two-dozen animals that scientists discovered recently in the highlands of the northern Amazon.

Among the new creatures are four frogs, six species of fish, a dozen kinds of dung beetles, and a type of ant never before seen by scientists.

One of the expedition's welcome surprises was the re-discovery of an armored catfish that had not been seen in 50 years and was presumed extinct due to contamination by local gold mines.
