Diplosoma simile and Trididemnum cyclops are considered to be wide-spreading species based on the faunal surveys in the Ryukyus, Taiwan, Panama, and some oceanic islands in North Pacific (i.e., Minami Daito-jima, Bonin Islands, Hawai'i). Especially, D. simile has already spread in not only Indo-Pacific but also in Caribbean Panama. In the monthly monitoring of drifting seaweeds, colonies of T. cyclops were found on the Sargassum leaves, indicating that these species have a long-dispersal ability using drifting materials. These two species are the most possible candidates that expand the distribution range toward higher latitude following the increase of seawater temperature.Larval spawning was confirmed by direct observation and histological and electron-microscopic studies in a cyanobacteriosponge Terpios hoshinota that encrusts scleractinian corals.A new species of a colonial hydroid Zancrea sango was described. This species spread the colonies on a scleractinian coral colony.

根据在琉球、台湾、巴拿马和北太平洋的一些海洋岛屿（如南大东岛、波林群岛、夏威夷）的区系调查，认为双歧蝶和独眼蝶是分布广泛的物种。特别是，明星病不仅在印太地区蔓延，而且在加勒比地区巴拿马蔓延。在每月的浮游海藻监测中，在马尾藻叶片上发现了独眼绦虫的群落，表明该物种具有利用漂流物进行长期扩散的能力。这两个物种是随着海水温度升高而向高纬度扩展分布范围的最有可能的候选者。通过直接观察和组织学和电子显微镜研究，证实了在硬核珊瑚外壳上的蓝藻海绵Terpios hoshinota中有幼虫产卵。报道了一种新的殖民地水螅虫桑科。这一种在硬核珊瑚群上散布殖民地。
