| [Note Guidelines] Photographer's Note |
Echinoderms are characterized by radial symmetry, several arms (5 or more, mostly grouped 2 left - 1 middle - 2 right) radiating from a central body (= pentamerous). The body actually consists of five equal segments, each containing a duplicate set of various internal organs. They have no heart, brain, nor eyes, but some brittle stars seem to have light sensitive parts on their arms. Their mouth is situated on the underside and their anus on top (except feather stars, sea cucumbers and some urchins.
They are exclusively marine. And occur in various habitats from the intertidal zone down to the bottom of the deep sea trenches and from sand to rubble to coral reefs and in cold and tropical seas.

GORGEOUS shot, nice clear colors and very easy on the eyes. The note was also useful.

Hello Czaldy,
This sea star looks like a jeel, indeed. Very nice POV and framing. Nicely visible patterns.
Best greetings,
Michal
