Abstract

Two subspecies of blue whale occur in Australian waters, (1) the pygmy blue whale (Balaenoptera musculus brevicauda) and (2) the Antarctic blue whale (Balaenoptera musculus intermedia). Understanding blue whale presence in Australian waters is critical to ensuring Australia’s protection of these marine mammals as both subspecies were heavily exploited during historical whaling. This short note documents pygmy blue whale sightings in New South Wales waters over the last 18 years. Observations were opportunistically made via citizen science and verified by scientists. Sightings in this note contribute to our limited knowledge of pygmy blue whale distribution along the east coast of Australia and may help understand the migratory movements of New Zealand pygmy blue whales off Australia and in the Tasman Sea. Overall, information presented in this note contributes to Australia’s national and international conservation efforts to protecting blue whales as a migratory and threatened species.
在澳大利亚悉尼附近偶然发现蓝鲸
蓝鲸的两个亚种出现在澳大利亚水域,(1)侏儒蓝鲸(Balaenoptera musculus brevicoda)和(2)南极蓝鲸(Baraenoptera musculus intermedia)。了解蓝鲸在澳大利亚水域的存在对于确保澳大利亚保护这些海洋哺乳动物至关重要,因为这两个亚种在历史捕鲸期间都遭到了严重剥削。这份简短的笔记记录了过去18年来在新南威尔士州水域看到的侏儒蓝鲸。观察是通过公民科学机会主义地进行的,并得到了科学家的验证。本说明中的景象有助于我们对澳大利亚东海岸侏儒蓝鲸分布的有限了解,并可能有助于了解新西兰侏儒蓝鲸在澳大利亚海域和塔斯曼海的迁徙。总的来说,本说明中提供的信息有助于澳大利亚国家和国际保护蓝鲸作为一种迁徙和受威胁物种的努力。

期刊介绍: The Royal Zoological Society publishes a fully refereed scientific journal, Australian Zoologist, specialising in topics relevant to Australian zoology. The Australian Zoologist was first published by the Society in 1914, making it the oldest Australian journal specialising in zoological topics. The scope of the journal has increased substantially in the last 20 years, and it now attracts papers on a wide variety of zoological, ecological and environmentally related topics. The RZS also publishes, as books, and the outcome of forums, which are run annually by the Society.
