Detailed explanation-1: -Warning coloration (or aposematic coloration) is the opposite of protective coloration. Bright colors on the upper surface of a frog’s skin usually mean that the frog is poisonous. Predators that attack a brightly colored frog quickly learn to avoid similar-looking ones in the future.

Detailed explanation-2: -The striking bright blues, yellows, and oranges of poison dart frogs are a classic example of warning coloration, sending a message to predators to stay away. But somewhat counterintuitively, these conspicuous colors may be helping the frogs hide in plain sight, according to a new study.

Detailed explanation-3: -Aposematism (Greek, apo = away, sematic = sign) is the use of warning coloration to inform potential predators that an animal is poisonous, venomous, or otherwise dangerous. Oftentimes orange or red patterns may be warnings (as in coral snakes), but do not assume that red is always a warning (see Chapter 7).
