Abstract

Verified records of the bull shark Carcharhinus leucas are lacking in the Maldives. This study provides the first confirmed evidence of 23 sightings observed from 2013 to 2023 in the central and southern atolls of this archipelago. Most of the sightings occurred in close proximity to inhabited areas, where food waste is often discarded into the water, or in several dive sites, suggesting the presence of this species in different locations around central and southern atolls. Although further research is required to fully investigate the C. leucas population in the Maldives, this report documents and confirms its presence in this region.

摘要

马尔代夫缺乏公牛鲨(白真鲨)的确切记录。本研究提供了2013年至2023年在该群岛中南部环礁观测到23次目击事件的首个确凿证据。大多数目击事件发生在靠近有人居住的地区,那里食物残渣经常被丢弃到水中,或者发生在几个潜水地点,这表明该物种存在于中南部环礁周围的不同地点。尽管需要进一步研究以全面调查马尔代夫的白真鲨种群,但本报告记录并证实了其在该地区的存在。
