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
Blurred lanternshark caudal fin with a well-developed lower lobe and a broad upper lobe with a ventral notch near the tip. The small, blocky dermal denticles are densely but irregularly arranged, each with a flat, truncate crown. The coloration is brown or gray above, with a pale spot over the pineal gland, and black below extending in faint markings over the sides of the head, under the pectoral fins, over the pelvic fins, and below the caudal peduncle. Like other lanternsharks, the blurred lanternshark possesses a species-specific light-emitting photophores, which are not placed in prominent bands. The diet of the blurred lanternshark
