Determining where and when animals give birth is critical for establishing effective conservation management that protects vulnerable life stages (e.g., pregnant females newborns) places nursery grounds). To date, this information has been elusive in the case of highly migratory sharks wild. Here, we report on deployment a novel intrauterine satellite tag implanted two mobile apex predators, tiger shark (Galeocerdo cuvier) scalloped hammerhead (Sphyrna lewini), remotely documented location timing by oceanic animal This technology will be especially valuable protection threatened endangered species, pupping grounds priority.
