the golden frog is capable of secreting poison to help protect themselves from predators. In the case of the golden frog, this is a water-soluble neurotoxin called zetekitoxin.
Some animals that protect themselves with their color patterns are the chameleon, the ladybug, the gila monster, and the poison dart frog. The eastern newt is reddish-orange in color, a warning to other animals that it is highly toxic.
