- Title
Female nuptial signal advertises spawning readiness in a population of Halichoeres margaritaceus on the Great Barrier Reef, Australia.

- Abstract
Females of some polygynous fish species display female nuptial signals (FNSs), advertising spawning readiness to potential mates. Halichoeres margaritaceus, a polygynous coral reef fish, reportedly display red belly color and a unique bobbing behavior as FNSs advertising spawning readiness. In this study, I examined whether FNSs were observed in an H. margaritaceus population in Australia. Females in this study displayed red belly color as an FNS, although at a lower intensity than that reported in a Japanese population. Contrary to observations made in the Japanese population, bobbing behavior performed by females in this study showed no temporal trend as spawning approached, indicating bobbing behavior did not function as an FNS in the Australian population. The role of local selective pressures on FNS intensity and lifetime reproductive benefits H. margaritaceus may potentially gain in utilizing FNSs are briefly discussed.
