The color variety ranges from black, brown, tan, and mudd… There are approximately 170 species of frogs considered poison dart frogs, and they come in a large variety of shapes, sizes, colors, and patterns. Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These brightly colored amphibians are among the largest of the more than 100 poison dart frog species, averaging more than one inch in length. The Dendrobatidae famil…  Because of this, captive-bred animals do not possess significant levels of toxins as they are reared on diets that do not contain the alkaloids sequestered by wild populations. In general, females have a choice of mate. For the advanced hobbyist but great frogs once settled. Many species have dull or camouflaged colors, and have little to no toxins in their skin.  The lack of sexual dimorphism in some dendrobatid populations however suggests that sexual selection is not a valid explanation. Some choose to flee, However, of over 170 species, only four have been documented as being used for this purpose (curare plants are more commonly used), all of which come from the genus Phyllobates, which is characterized by the relatively large size and high levels of toxicity of its members.  The family Dendrobatidae currently contains 16 genera, with about 200 species. The poison dart frog's color can be yellow, gold, copper, red, green, blue, or black . They weigh 1 oz.

This is surprising given the frequency-dependent nature of this type of defense mechanism.
