Abstract

Killer whales, Orcinus orca, are known to be one of the most widespread cetaceans, inhabiting all the oceans of the world, but their presence in the Southern Caribbean has been scarcely recorded up to date. An unusual sighting of a killer whale is described for the first time in inshore waters of the Gulf of Morrosquillo. The whale was sighted on 22 March 2015 and it was a solitary individual of unrecognized sex that showed ongoing diving and surfacing behavior at a site 6.3 km from the coast with depths between 20 and 24 m. Its occurrence could be related to favorable environmental and oceanographic conditions and to the potential effect of recent seismic offshore oil and gas operations in the gulf, which may impact a whale’s location and behavior. This report contributes to the scarcity of information about the distribution of O. orca in the Caribbean Sea along the coast of Colombia.

哥伦比亚附近加勒比海近海新发现虎鲸

虎鲸虎鲸是分布最广的鲸目动物之一，栖息在世界各大洋，但迄今为止，它们在南加勒比地区的存在几乎没有记录。首次在莫罗斯奎洛湾近海水域发现了一头不同寻常的虎鲸。这头鲸鱼于2015年3月22日被发现，它是一只性别不明的孤独个体，在距离海岸6.3公里、深度在20至24米之间的地点表现出持续的潜水和浮出水面行为。它的出现可能与有利的环境和海洋学条件有关，也可能与海湾最近地震海上石油和天然气作业的潜在影响有关，这可能会影响鲸鱼的位置和行为。本报告导致哥伦比亚沿岸加勒比海虎鲸分布信息匮乏。

期刊介绍： A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format. CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience. So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
