Sea of stars
Starfish are not fish, of course, but rather close cousins of sand dollars and sea urchins. Just the sight of these stellar sea creatures is enough to excite even the most jaded of beachgoers. Plus, with their knack of showing up in the most romantic spots, they seem to be the perfect gauge for which beaches are the most scenic.
This striking neon blue effect is a completely natural phenomenon. The incredible image was taken by photographer Doug Perrine during a visit to Vaadhoo, one of the Raa Atoll islands in the Maldives. It captures a natural chemical reaction called bioluminescence, which occurs when a micro-organism in the water is disturbed by oxygen.
