Introducing the coolest relative of a jellyfish, the By-the-wind Sailor (Velella velella).
The deep blue body of the creature rests on the top of the ocean with
its tentacles hanging down below to catch its plankton prey. On top is
the Sailor’s characteristic stiff sail which behaves much the way a sail
of the ship does.

  1. It’s actually plankton that creates a glow when disturbed. Super fascinating stuff… makes me wish I had gone through to be a marine biologist.

  2. Had a massive tidal change when I was a kid – think it was a storm. We had an entire beach covered in these things… they come in other colors too, but mostly blue. Even the seagulls couldn’t keep up with eating all of them. 

    Where are these pics from?
