With snakes, the brighter their colour is, the more venomous they are, a warning to their predators; this one is harmless, although very colourful. It resembles the coral snake with which it cohabits, protecting itself by mimicry.
Like all snakes, it has a long, forked tongue that it uses to gather information. Its teeth are used to hold its prey, which it swallows in whole with help of its extendable jaws. It measures 100 to 120 cm, and sheds its old skin to grow: it moults. They are oviparous, laying 10 to 15 eggs.
IUCN Status : least concern (Appendix III)
