We present the first photographic records of the tiger shark (Galeocerdo cuvier) at the remote Rapa Nui (Easter Island) in the south-east Pacific. Previous anecdotal sightings exist for tiger sharks in this region; however these records have not been reported within the scientific domain. The present sighting occurred in a period of unusually warm sea surface temperature, which has been shown to influence tiger shark range extensions elsewhere. Novel and historic species occurrence records are valuable for determining and predicting species' environmental tolerances, migratory routes, and distributional limits.
我们首次在东南太平洋偏远的拉帕努伊岛（复活节岛）拍摄到了虎鲨（Galeocerdo cuvier）的照片。此前在该地区曾有过虎鲨的传闻目击记录，但这些记录并未在科学界报告过。本次目击事件发生在一段海面温度异常温暖的时期，这种情况已经被证明会影响到其他地方的虎鲨的活动范围。新的和历史性的物种出现记录对于确定和预测物种的环境容忍度、迁徙路线和分布范围非常有价值。
