The dyeing dart frog, dyeing poison 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. Dyeing poison dart frog_sentence_0

It is among the largest species, reaching lengths of 50 mm (2.0 in). Dyeing poison dart frog_sentence_1

This species is distributed throughout the eastern portion of the Guiana Shield and Venezuela, including parts of Guyana, Suriname, Brazil, and nearly all of French Guiana. Dyeing poison dart frog_sentence_2

Poison Dyeing poison dart frog_section_0

Like most species of the genus Dendrobates, D. tinctorius is highly toxic if consumed. Dyeing poison dart frog_sentence_3

It produces pumiliotoxins and allopumiliotoxins that the frog uses for self-defense. Dyeing poison dart frog_sentence_4

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. Dyeing poison dart frog_sentence_5

In the case of D. tinctorius, the toxins cause pain, cramping, and stiffness when the frogs are handled roughly. Dyeing poison dart frog_sentence_6

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. Dyeing poison dart frog_sentence_7

As it is such a variable species, different color morphs of D. tinctorius have varying degrees of toxicity and many can cause serious effects on humans including death. Dyeing poison dart frog_sentence_8

Local tribes use D. tinctorius for decoration. Dyeing poison dart frog_sentence_9

Feathers are plucked from the back of young parrots and the frogs are rubbed on the parrots' exposed skin. Dyeing poison dart frog_sentence_10

When the feathers regrow, the toxin causes them to appear yellow or red rather than green. Dyeing poison dart frog_sentence_11

These altered feathers are highly prized by the indigenous tribes. Dyeing poison dart frog_sentence_12

Description Dyeing poison dart frog_section_1

The dyeing poison dart frog is large for a poison dart frog, but may be smaller than Phyllobates terribilis and Ameerega trivittata. Dyeing poison dart frog_sentence_13

Many small forms of D. tinctorius reach 3.5 cm long; most morphs are around 5 cm in length or slightly bigger; some of the larger morphs may exceed 7 cm, although large ones are usually closer to 5.5 cm long. Dyeing poison dart frog_sentence_14

For some time, captive individuals were thought to be incapable of reaching the sizes of wild specimens; however, later evidence suggested captive individuals do not reach their maximum potential size possibly due to vitamin and mineral deficiencies. Dyeing poison dart frog_sentence_15

More recently, breeders had success raising dyeing poison dart frogs to very large sizes. Dyeing poison dart frog_sentence_16

Dendrobates tinctorius is one of the most variable of all poison dart frogs. Dyeing poison dart frog_sentence_17

Typically, the body is primarily black, with an irregular pattern of yellow or white stripes running along the back, flanks, chest, head, and belly. Dyeing poison dart frog_sentence_18

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. Dyeing poison dart frog_sentence_19

The legs range from pale blue, sky blue or blue-gray to royal blue, cobalt blue, navy blue, or royal purple and are typically peppered with small black dots. Dyeing poison dart frog_sentence_20

The "Matecho" morph is almost entirely yellow and with some black, with only a few specks of white on the toes. Dyeing poison dart frog_sentence_21

Another unique morph, the citronella morph, is primarily golden yellow with tiny splotches of black on its belly and royal blue legs that have no black dots. Dyeing poison dart frog_sentence_22

Males are typically smaller and more slender than females, but they have larger toe discs. Dyeing poison dart frog_sentence_23

The toe discs of female dyeing poison dart frogs are circular while those of the males are heart-shaped. Dyeing poison dart frog_sentence_24

Also the females have arched backs as opposed to males who have curved ones. Dyeing poison dart frog_sentence_25

Distribution Dyeing poison dart frog_section_2

It exists in discrete patches throughout this region, being restricted to "highland" (up to 350 m (1,150 ft)) areas. Dyeing poison dart frog_sentence_26

While this species can be found at sea level, individuals have been collected at the base of nearby hills or mountains. Dyeing poison dart frog_sentence_27

The isolation of populations has presumably occurred as a result of the erosion of these highland areas and the seasonal inundation of the inter-patch areas. Dyeing poison dart frog_sentence_28

Morphs Dyeing poison dart frog_section_3

The species encompasses a great diversity of color and patterning variants (subspecies and morphs). Dyeing poison dart frog_sentence_29

Some batrachologists suspect that some of these are actually different species. Dyeing poison dart frog_sentence_30

Etymology Dyeing poison dart frog_section_4

The specific name comes, however, not from the variety of colors, but from the legends of some indigenous tribes. Dyeing poison dart frog_sentence_31

It has been said that tribe members used the frog poisons to cause green parrot feathers to grow different colors. Dyeing poison dart frog_sentence_32
