Cobalt Poison Dart Frog (Dendrobates tinctorius)

The Cobalt Poison Dart Frog (Dendrobates tinctorius) is a vividly colored amphibian native to the rainforests of South America, particularly in Suriname and Brazil. Known for its striking blue limbs and dark body speckled with lighter patterns, this small frog serves as a warning to predators—its skin contains potent toxins derived from its natural diet. Measuring around 4–5 cm, the cobalt dart frog is diurnal and highly territorial, often displaying bold behaviors despite its size. In the wild, its toxicity serves as an effective defense, though captive-bred individuals are typically non-toxic due to a different diet.
