Napoleon Invasion

A humphead wrasse, also known as a Napoleon wrasse, builds a living frame as it swims through a school of fish in the waters off Australia. Photographer Christian Miller captured the shot on a windy day right after a cyclone had passed the far northern Great Barrier Reef. “Never before [had I seen] that many glass fish on this particular coral bommie [outcrop],” he writes.
