Everybody knows that milk snakes mimic coral snakes, as well as of other coral snake mimics. However, I'd like to learn more of other venomous snake mimics, such as snakes that mimic vipers. Now, I'm mainly looking into snakes that visually(ex. Patterns/Colors) look like vipers, as opposed to behave like them, since it has been mentioned before that they undergo mimicry behaviour, such as tail rattling, hooding, and even head flattening. As far as colors, morphology, and patterns go though, not much is said beyond milk snakes. All I know of are Viper Boas and Rough Scaled Sand Boas, but I'm also curious to ask, would you all say Nerodia spp. are considered mimics of Agkistrodon spp.? I'm curious to learn more!
