This result, due to confusion based on a visual effect and the whitespots "acting" themselves as a tight school of small prey, answers two baffling questions about oceanic whitetip sharks: how can such slow-moving creatures have as their prey some of the fastest moving oceanic fishes (e.g., tunas, various scombroids, dolphinfsh, etc.) and why are its fins (= paddles) so much larger than those of other sharks?
