Species of amphibian

The dyeing poison dart frog (Dendrobates tinctorius), also known as the cobalt poison frog, tinc (a nickname given by those in the hobby of keeping dart frogs), or dyeing poison frog, is a species of poison dart frog. It is among the most variably colored and largest species of poison dart frogs, typically reaching snout–vent lengths of about It is distributed in the eastern portion of the Guiana Shield, including parts of French Guiana, Guyana, Suriname and Brazil. While this species can be found at sea level, it is mostly found in upland areas, for example in hills or at the base of mountains. The isolation of populations has presumably occurred as a result of the erosion of these highlands and the seasonal inundation of the inter patch areas. A study shows that Dendrobates tinctorius tadpoles can survive in pools having a high level of KH, vertical height of and salinity up to 955 ppm.

The dyeing poison dart frog is large for a poison dart frog, but may be smaller than Phyllobates terribilis and Ameerega trivittata. Small forms of D. tinctorius reach in snout–vent length; most variants are around in length or slightly bigger; some of the largest variants may reach Although some variants are smaller or larger, differences tend to be average with some overlap in full size range (i. e., a large individual of a small variant often is comparable in size to a small individual of a large variant). Males are typically smaller and more slender than females, but they have larger toe discs. The toe discs of female dyeing poison dart frogs are circular while those of the males are heart shaped. Also the females have arched backs as opposed to males who have curved ones.

Dendrobates tinctorius is one of the most variably colored and patterned of all poison dart frogs, with more than 30 recognized variants or morphs. Each main variant or morph is unique to a locality or region, although there is also a level of individual variation in each. Typically, the body is primarily black, with an irregular pattern of yellow or whitish stripes running along the back, upper flanks and head, and an irregular pattern of blue stripes on the lower flanks, belly and throat. The legs typically are blue peppered with small black; the blue ranges from pale blue, sky blue or blue gray to royal blue, cobalt blue, navy blue or greenish blue. In some variants or morphs, however, the body and legs may be primarily blue (as in the "azureus" of southern Suriname, now usually considered a morph of the dyeing poison dart frog), primarily yellow, or primarily whitish. The "Matécho" morph from Saül, French Guiana, is mostly yellow and with some black, with only a few specks of white on the toes and sometimes whitish on the underparts. Another variant, the "Citronella" morph from the vicinity of Kasikasima, Suriname, is primarily deep yellow with some black blotches on the back and head, and royal blue legs and underparts with tiny black spots.
