1. Emsleyan/Mertensian mimicry involves a dangerous species imitating a less dangerous one.
2. This type of mimicry is named after naturalist John Emsley and herpetologist Robert Mertens.
3. The mimicry serves to protect the toxic species by creating confusion among predators about the level of danger posed.
4. It contrasts with Batesian and Müllerian mimicry, where either harmless or equally harmful species are involved.
5. Examples include certain venomous snakes that resemble non-venomous ones to avoid predation.
