Abstract

Occurrence of multiple whitetip reef sharks Triaenodon obesus in the Atlantic Ocean is reported for the first time from near a sunken ferry off the Paraná coast in south-eastern Brazil. This occurrence is hypothesized to have been caused by either a human introduction or a remarkably long oceanic displacement.

摘要

首次报道在巴西东南部巴拉那海岸附近一艘沉没渡轮附近出现多条白鳍礁鲨（Triaenodon obesus）。据推测，这种情况是由人为引入或极长距离的海洋迁徙造成的。
