Banded archerfish colourations, such as yellow, have been observed. Four to six broad black bars may be present on the dorsal side. The first bar is found anterior to the operculum, the bony plate covering the gills, and the second is found behind the operculum. The third bar is found below the origin of the dorsal fin, the fourth bar below the soft dorsal, and the fifth (if any) on the area between the anal fin and caudal fin (caudal peduncle). These bars become shorter as the fish ages. The lateral line curves upwards at the area between the fourth and ninth
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
