Red Sea in February is full of strange translucent creatures. It's the jellyfish, ctenophores and salps. They have appeared on our planet long before us, but now for us they look like alien race, but not the typical representatives of the animal world. Ocean and the creatures who inhabit - it's another universe, the cosmos, and you can see it by yourself. Here they are.

Aurelia is the most common but one of the most beautiful jellies in the world ocean.
Colony of salps Pegea confederata
Cyclosalpa sp. colony 
Comb jelly Leucothea sp. closed with retracted tentacles
And opened...
They are Spaceships of the Imagination. But real.
It blows my mind. every. time.
