St. John Sea Creatures: Moon Jelly

Moon Jelly Aurelia aurita

Seems to be the season for these creatures as I saw a quite a few on yesterday’s snorkels at Blue Cobblestone Beach and Yazwi Point.

Some Moon Jelly Facts:

They consist almost entirely of water and unlike most animals, they have no bones, no brain and no heart.

Their sting is generally harmless to human beings, however some sensitive individuals may feel a mild irritation.

They are eaten by sea turtles, especially the Leatherback and for this reason it is dangerous to put plastic bags in the sea as they may be mistaken for jellyfish and eaten by the turtles, which could choke them.
