Caudal luring species and allegedly by two lizards, though other interpretations (e.g., distraction) seem more plausible for the lizards. Caudal luring also occurs in a shark, the tasselled wobbegong, "Eucrossorinus dasypogon" and very likely in the pelican eels, "Eurypharynx", which possess a bioluminescent tail tip. The behavior is associated with sedentary predators whose diets include animals susceptible to a worm-like (or fish-like, in the case of "Eucrossorinus" and perhaps "Eurypharynx") luring appendage. Snakes generally lure small ectotherms (e.g., frogs and lizards), although luring of birds has been demonstrated (Spider-tailed horned viper) and luring of insectivorous mammals is suspected. Caudal luring occurs most
Caudal luring difference is in the snake's posture and especially in the nature and outcome of the behaviour in reference to the encounter with prey. Other caudal luring-like movements occur as warning signals and are induced by stressful circumstances. Thus identifying caudal luring entails observing the effect that tail movements have on prey species, a burden of evidence that is woefully lacking in much of the literature on this intriguing behaviour. Caudal luring Caudal luring is the use of tail movements by a predator to attract prey animals that think the tail is a worm or other smaller prey and approach within
