Phyllobates terribilis "Mint"

Phyllobates terribilis 'Mint' are not very variable, and most individuals are virtually identical to each other. When young, mint terriblis come out of the water as a mostly black frog with a 'U' of colour on the dorsum. As they age, this 'U' spreads and eventually covers 95% or more of the frog's body, with a bit of black remaining around the nostrils/mouth and toes.
