抄録: Similarities on reproductive character traits and habitats of dragonets were depicted in similarity phenograms. In the reproductive traits phenogram, except for R. planus, all members of the genus Repomucenus are grouped in one cluster, while R. japonicus is clustered with F. altivelis. In the habitat phenogram, C. japonicus is clustered with the four Repomucenus species, while R. planus belonged to an independent cluster. The clustering of all Repomucenus species studied in the reproductive traits accorded well with that of the habitat phenogram, whereas C. japonicus is clustered differently in the reproductive and habitat phenograms. The depth distribution and abundance data show that, in general, the environment at l20 m depth zone is suitable for the dragonet species in Tosa Bay, while the dominant Repomucenus group tends to occupy the shallower waters of the bay. Here, we also provide notes on the evolutionary history of dragonets in the bay. Potential competitions among dragonets for resource requirements along the depth gradients of Tosa Bay are also discussed.
