Determining where and when animals give birth is critical for establishing effective conservation management that protects vulnerable life stages (e.g., pregnant females and newborns) and places (e.g., nursery grounds). To date, this information has been elusive in the case of highly migratory sharks in the wild. Here, we report on the deployment a of novel intrauterine satellite tag implanted in two highly mobile apex predators, the tiger shark () and the scalloped hammerhead (), that remotely documented the location and timing of birth by a highly migratory oceanic animal in the wild. This novel technology will be especially valuable for the protection of threatened and endangered shark species, where protection of pupping and nursery grounds is a conservation priority.
确定动物的分娩地点和时间对于制定有效的保护管理措施至关重要，这些措施可以保护脆弱的生命阶段（如怀孕的雌性和新生儿）和场所（如托儿所）。迄今为止，在野生高度洄游性鲨鱼的情况下，这些信息很难获得。在这里，我们报告了一种新型宫内卫星标签的部署情况，该标签被植入了两种高度移动的顶级掠食者——虎鲨（）和锯鲨（）中，这种标签通过一种高度洄游的海洋动物在野外远程记录了分娩的地点和时间。这项新技术对于保护受到威胁和濒危的鲨鱼物种尤其有价值，因为保护繁殖地和托儿所是保护的优先事项。
