摘要

有关虎鲸（虎鲸）在热带水域觅食生态的知识十分匮乏。在西南印度洋，机会性目击为更好地了解虎鲸的行为、饮食和分布提供了宝贵的信息来源。在这里，我们汇编了虎鲸在西南印度洋捕食鳍鳃亚纲动物的现有记录，包括在该地区发现的三种未被描述的猎物：巨蝠鲼（Mobula birostris）、镰鳍魔鬼魟（Mobula tarapacana）和虎鲨（Galeocerdo cuvier）。记录这些观察结果对于增加虎鲸在热带地区的生态学知识以及它们可能对猎物种群产生的连锁影响非常重要。

Killer Whale Predation on a Giant Manta Ray (Mobula birostris), a Sicklefin Devil Ray (Mobula tarapacana) and a Tiger Shark (Galeocerdo cuvier) in the Southwest Indian Ocean

Knowledge of killer whale (Orcinus orca) feeding ecology in tropical waters is scarce. In the southwest Indian Ocean, opportunistic sightings provide a valuable source of information to better understand their behaviour, diet and distribution. Here, we compile existing records of killer whale predation on elasmobranchs in the southwest Indian Ocean, including sightings of three undescribed prey species regionally: a giant manta ray (Mobula birostris), a sicklefin devil ray (Mobula tarapacana) and a tiger shark (Galeocerdo cuvier). Documenting such observations is important to increase knowledge on killer whale ecology in the tropics and the cascading impact they might have on prey populations.

期刊介绍： African Journal of Ecology (formerly East African Wildlife Journal) publishes original scientific research into the ecology and conservation of the animals and plants of Africa. It has a wide circulation both within and outside Africa and is the foremost research journal on the ecology of the continent. In addition to original articles, the Journal publishes comprehensive reviews on topical subjects and brief communications of preliminary results.
