Not all wildlife moments are dramatic—some unfold in perfect stillness. The grey seal resting on the shores of the Orkney Islands, Scotland, is a perfect example. Grey seals are among the UK"s largest native marine mammals, with the country supporting around 40% of the world"s population. Despite their size, they are remarkably adaptable sleepers. Rather than settling into one long stretch, grey seals nap in short, flexible bursts shaped by their surroundings.
