The unusual dorsal coloration of this poison dart frog (Anomaloglossus sp.) differs from a similar species (Anomaloglossus baeobatrachus) found at the same sites. Poison dart frogs are famous for the powerful
toxins they secrete – this poison is used by local people to hunt for
food, but it also holds enormous potential to yield new medicines.
Chemicals from some poison dart frogs have already been used to develop
painkillers, muscle relaxants, and heart stimulants
