Diadophis punctatus

The cloacal secretion ofL. dulcis also repels its predators, ophiophagous snakes. All flve species of the tested colubrid snakes are repelled, including the ophiophagous species Diadophis punctatus and Lampmpeltis triangulum. However, the cloacal secretion attracts conspecifics. This attraction possibly evolved first as the most important function of the secretion for the blind snakes (Watkins et ah, 1969).
