An unprecedented number of basking sharks were spotted off Cornwall recently. 460, in fact. Until then, the highest number seen in the area was 300. The high number has been attributed to the abundance of plankton in the area.
But one thing puzzles me. How does one go about counting a mass of constantly-moving sharks? Especially when they’re not all tagged or otherwise individually identifiable.
