已知生活在公海的唯一昆虫是几种海鳅属（异翅目：鳅科）。我们在热带西太平洋采集了 4 个物种，并测量了 132 个样本的热彗发温度 (HCT) 和过冷点 (SCP)。所有物种的 SCP 相对较低（范围在零下 18 摄氏度到零下 19 摄氏度之间）并且相似。 HCT 水平存在显着的物种间差异。最低的 HCT 为 32.9 摄氏度，发现于 1822 年的 Halobates micans Eschscholtz，它分布在热稳定的热带水域。在 Halobates sericeus Eschscholtz 和 Halobates germanus White, 1883 中观察到的最高 HCT 水平分别为 36.6 摄氏度和 36.0 摄氏度，主要出现在热波动较大的栖息地（分别为亚热带和暖温带水域以及沿海水域）。一个新物种，H. sp。 （描述过程中）显示中间 HCT 为 34.8 摄氏度。此外，我们发现在物种和个体水平上 HCT 和 SCP 值之间存在显着的负统计相关性。我们根据滑冰运动员的热生理学与其分布之间的假定关系来讨论我们的结果。 (c) 韩国应用昆虫学会、台湾昆虫学会和马来西亚植物保护学会，2013 年。Elsevier B.V 出版。保留所有权利。
The only insects known to live in the open ocean are several species of sea skaters of the genus Halobates (Heteroptera: Gerridae). We have collected four species in the tropical western Pacific Ocean and measured heat coma temperature (HCT) and supercooling point (SCP) in 132 specimens. The SCPs were relatively low (ranging between - 18 degrees C and - 19 degrees C) and similar in all species. Significant inter-species differences were found in the level of HCT. The lowest HCT 32.9 degrees C was found in Halobates micans Eschscholtz, 1822, which is distributed in thermally stable tropical waters. The highest HCT levels of 36.6 degrees C and 36.0 degrees C were observed in Halobates sericeus Eschscholtz and Halobates germanus White, 1883, respectively, mostly occurring in thermally more fluctuating habitats (subtropical and warm temperate waters, and coastal waters, respectively). A new species, H. sp. (under process of description) showed an intermediate HCT of 34.8 degrees C. In addition, we found significant negative statistical correlation between HCT and SCP values at the species and individual levels. We discuss our results in the light of putative relationship between thermal physiology of sea skaters and their distribution.
