What is the purpose of the bright coloration seen in species like the Fire Salamander?

Answer

To warn potential predators that the animal is toxic or unpalatable (aposematism)

The striking yellow or orange spots/bands on the black skin of the Fire Salamander serve as a visual warning signal, indicating toxicity to predators through a physical manifestation of aposematism.
