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
Pethia cumingii at the base of the caudal peduncle posterior to base of anal. Both blotches are widest at the lateral line. Eye pale yellow or white. Dosal and ventral orange, with two horizontal rows of 5-7 black spots on dorsal which has a black tip to its anterior spine. Remaining fins yellow (Daraniyagala,1952).Dorsally olive, the side being silvery with a golden sheen. There are two vertically elongate blotches rather larger than the eye, one above the anal fine and the other above and behind the operculum. The dorsal and pelvic fines have yellow (Daraniyagala,1952 / Pethiyagoda 1991). Fins. D II.8, A
