The Mandarin newt can grow up to 20 cm (8 inches) long. It has a ridged orange head, a darker body with an orange dorsal ridge, and orange bumps along its sides, which are poison glands. The orange coloration warns predators of its toxicity. Its poison glands release toxins when squeezed, making it dangerous to potential predators.
