[ 1 ] This frog has been seen on the international pet trade, but because it is also raised in captivity, it is difficult to tell whether any given frog was raised in captivity ...

Despite resembling the similarly-small poison dart frogs of Latin America, which also communicate their toxicity to potential predators through aposematism, Mantella species like the Baron's mantella are only distant taxonomic relatives.
