Blue poison dart frog

The blue poison dart frog or blue poison arrow frog (Dendrobates tinctorius "azureus") is a poison dart frog found in the "forest islands" surrounded by the Sipaliwini Savanna in southern Suriname. Its indigenous Tiriyo name is okopipi. The name "azureus" comes from its azure blue color. While first described as a valid species and usually recognized as such in the past, recent authorities generally treat it as a morph of D. tinctorius, although a few treat it as a subspecies of D. tinctorius or continue to treat it as its own species. To what extent it differs from the blue D. tinctorius in southern Guyana, adjacent Pará (Brazil) and possibly far southwestern Suriname, is also a matter of dispute, and many herpetologists, as well as many people keeping poison dart frogs in captivity, have not distinguished these, with all commonly being identified as "azureus".
