- Abstract
Reproductive behavior of the blenniid fish Meiacanthus kamoharai was investigated in Tachibanaura Bay, Kochi Prefecture, Japan in 2016–2018. The species is sexually dimorphic, with males having more elongated caudal-fin rays and longer pelvic-fin rays than females. During the spawning season, males exhibited two types of coloration, 'blackening' and 'whitening', which were observed during male–male competition and the increase of sexual motivation in males, respectively. The mating system was suggestive of male-territory-visiting polygamy, with males assuming exclusive parental care of multiple batches in the nest. Courtship displays by a female towards males were frequent in June and July, while males positively exhibited displays in August, indicating that the courtship roles of individuals changed seasonally during a single spawning season.
