| Research Abstract |
To clarify mate-choice copying behaviour of female Rhabdoblennius ellipes, we observed female spawning pattern in detail and conducted mate-choice experiment in the field. Several females were observed near the spawning nest, and then most of them spawned with the male without the male courtship displays. In the mate-choice experiment, focal females spawned with unpreferred males after forced mating between those males and model females. These results strongly suggested the presence of female mate-choice copying behaviour in this species.
