Epinephelus labriformis Epinephelus labriformis Epinephelus labriformis, commonly called starry grouper or flag cabrilla among various other vernacular names, is a species of marine fish in the family Serranidae. The starry grouper is medium-sized fish which grows up to 60 cm. From: "The body of the starry grouper is robust and compressed. The end of the top jaw is exposed. The operculum edge has 3 flat spines; the pre-operculum is without spines. The caudal fin is rounded. The lateral line is complete, it ends at the caudal fin base and is smoothly arched. The scales are rough and relatively small." The starry grouper
Caudal luring are a number of other behavioural interpretations for a wiggling appendage, and luring-like motions are associated with several other behavioural contexts (e.g., defence, stress, etc.). Caudal luring is thought to have evolved from a caudally localised intention movement (a behaviour derived from locomotor movements). Essentially, the act of remaining stationary while sensing prey produces general nervous system excitation that gets released in the form of tail movements. Caudal luring is not merely tail undulations, but must specifically be attractive to prey. Caudal distraction is another behaviour used by snakes, and the tail motions are very similar to caudal luring. The
