Poison dart frog’s bright colors also work as camouflage - science news in brief

However, this defense strategy is not always effective, as some predators have developed tolerance to the frogs’ toxins. Interestingly, according to a new study, the colors also work as camouflage, thus providing additional protection for the frogs. Although quite visible from close-by, when viewed from far away, the colors blend easily into the environment, making the frog almost invisible.
