摘要在新西兰首次记录到上层海洋蓝鼻幼鱼Hyperoglyphe antarctica （Carmichael 1818）。1996年9月在北岛西海岸nga Motu/Sugar Loaf群岛附近的漂浮物下收集了两个标本，1997年9月在北岛东海岸Cape Kidnappers以东的一块拖网中发现了至少20个标本。标准长度在65至87.3毫米之间的活标本具有神秘的颜色，并且能够将其身体颜色从深铜青铜色变为蓝色。新鲜死亡的标本缺乏在其他已知与水母有关的高象形动物幼崽身上发现的厚粘膜。我们认为南极南极人在北岛的下东海岸可能会增加，因为在东开普省和怀拉拉帕涡流中保留了与漂浮物相关的幼鱼，并且在澳大利亚东南部产卵的幼鱼可能会通过塔斯曼流到达新西兰。
Abstract Epipelagic juvenile bluenose, Hyperoglyphe antarctica (Carmichael 1818), are recorded from New Zealand for the first time. Two specimens were collected beneath flotsam nearNga Motu/Sugar Loaf Islands, west coast North Island in September 1996, and at least 20 were found inside a piece of trawl net drifting east of Cape Kidnappers, east coast North Island in September 1997. Live specimens between 65 and 87.3 mm standard length were cryptically coloured and were able to change their body colour from dark coppery‐bronze to blue. Freshly dead specimens lacked the thick mucous coat found in juveniles of other Hyperoglyphe species known to associate with jellyfish. We suggest that H. antarctica recruitment may be higher along the lower east coast North Island because of retention of flotsam‐associated juveniles in the East Cape and Wairarapa Eddies, and that juveniles spawned off south‐east Australia may reach New Zealand in the Tasman Current.
