Dendrobates tinctorius is one of the most variable of all poison dart frogs. Typically, the body is primarily black, with an irregular pattern of yellow or white stripes running along the back, flanks, chest, head, and belly. In some morphs, however, the body may be primarily blue (as in the "azureus" morph, formerly treated as a separate species), primarily yellow, or primarily white.
