The dyeing dart frog, tinc (a nickname given by those in the hobby of keeping dart frogs) or dyeing poison frog, ''Dendrobates tinctorius'', is a species of poison dart frog. It is among the largest species, reaching lengths of . This species is distributed throughout the eastern portion of the Guiana Shield, including parts of Guyana, Suriname, Brazil, and nearly all of French Guiana.
== Poison ==
Like most species of the genus ''Dendrobates'', ''D. tinctorius'' is highly toxic if consumed. It produces pumiliotoxins which the frog uses for self-defense. While pumiliotoxins are weaker than their derivative allopumiliotoxins and the batrachotoxins secreted by ''Phyllobates'' species, they are sufficiently toxic to discourage most animals from feeding on them. In the case of ''D. tinctorius'', the toxins cause pain, cramping, and stiffness when the frogs are handled roughly. Due to the toxins of the frogs, animals that feed on ''D. tinctorius'' will typically learn to associate the bright colours of such frogs with the vile taste and pain that occurs after a frog is ingested. As it is such a variable species, different color morphs of ''D. tinctorius'' have varying degrees of toxicity.
Local tribes use ''D. tinctorius'' for decoration. Feathers are plucked from the back of young parrots and the frogs are rubbed on the parrots' exposed skin. When the feathers regrow, the toxin causes them to appear yellow or red rather than green. These altered feathers are highly prized by the indigenous tribes.
