In perfect camouflage:
This Sargassumfish (Histrio histrio), a frogfish species (Antennariidae), lives on Sargassum sea weed (Sargassum muticum) only. The sea weed drifts in large carpets on sea surface and gives living space for many small fishes.
Left in the picture there are some reflections from sea surface. Background is the sky with clouds.
It took me one and a half hour to capture a good image of this very hard to find species.
