Abstract

Whale-associated barnacles are intriguing in terms of their planktonic food sources, mating habits, and mechanisms of host attachment. We present observations of the whale-associated barnacles Coronula diadema (Linnaeus, 1767) and Conchoderma auritum (Linnaeus, 1767) obtained from dead humpback whales (Megaptera novaeangliae (Borowski, 1781)) collected in Korea. Shell bases of Coronula diadema are inflected and sharp-edged with hollow coring tubes at the periphery. The coring tubes are filled with whale skin, supporting the model that shell accretion into the whale skin is achieved by basal constriction to achieve strong attachment. Conchoderma auritum attaches to the shell surfaces of Coronula and has a pair of tubular ear-shaped structures on the capitulum. Both species have short and thick-segmented cirri that allow feeding in strong currents. The distal ends of the cirri in both species are often equipped with sharp, large claw-like setae, which are likely used to capture large zooplankton for food. Coronula diadema and Conchoderma auritum are simultaneous hermaphrodites. Coronula diadema can mate up to nine surrounding individuals. Conchoderma auritum lives in clumps and mating group size can up to 26 individuals.

鲸藤壶如何生活在它们的寄主上？日冕冠状花序（Linnaeus，1767）和金龟皮病（Linnaeus，1767）（Cirripedia：Thoracicalcarea）的功能形态和交配群大小

摘要

与鲸有关的藤壶在其浮游食物来源，交配习惯和寄主依附机制方面颇具吸引力。我们呈现了从在韩国收集的死座头鲸（大头鲸新斑蝶（Megaptera novaeangliae，波罗夫斯基，1781））获得的与鲸有关的藤壶Coronula diadema（林奈，1767）和金龟属耳霉（林奈，1767）的观察结果。将Coronula冠状动脉的壳基弯曲，并在外围用空心取芯管锋利地磨边。取芯管中充满了鲸鱼皮，支持通过基部收缩使鲸鱼皮增生以实现牢固附着的模型。耳垢科豆附着于冠状壳的壳表面并且在头管上有一对管状的耳状结构。两种物种都有短而粗的卷毛，允许以强电流觅食。在这两个物种中，触毛的末端通常配备有锋利的大型爪状刚毛，很可能用来捕获大型浮游动物作为食物。冠状胎冠和金龟皮是同时的雌雄同体。日冕冠可以与9个周围的人交配。耳豆科豆科动物生活在团块中，交配组的规模可多达26个个体。
