摘要

The flamboyant cuttlefish Metasepia pfefferi is renowned for its bold and colorful body patterns, yet the functions of these displays and other behaviors remain largely unknown. We conducted two field studies in Indonesia using SCUBA and video to record its behavior under natural conditions. Camouflage via background matching and masquerade is the common primary defense against predators, and is also used offensively to approach prey closely. This species rarely uses its "flamboyant" bright conspicuous displays in nature; they were observed only during courtship or as secondary defense when a large fish closely approaches it. Males are only 10-60% the size of females and they court her with a vivid and dynamic Flamboyant Display, which appears to be one of the most elaborate among cephalopods. Conversely, females remain camouflaged and show no conspicuous courtship behaviors. When two males courted or mate-guarded a single female, unilateral signaling of aggression was observed. Twenty matings were recorded among 5 pairs of cuttlefish; they were in the "head-to-head" position and lasted only 3 s. Females were choosy; they required males to court for long periods and rejected 50% of males that attempted to mate with them. Females lay ca. 25 eggs per batch, roughly 6-7 min apart, usually during morning hours and with no male present. They often deposit eggs in coconut shells that occupy this open sandy habitat. This small species is cryptic and spends the vast majority of each day in a variety of highly camouflaged body patterns.
