St. John Virgin Islands Sea Creatures: Moon Jellyfish Aurelia aurita
Moon Jellyfish
The moon jellyfish is the most commonly found jellyfish in St. John
waters. It feeds mostly on plankton. They can propel themselves to
a limited degree, but, by and large, they drift about with the currents.
The moon jellyfish can produce a mild sting in sensitive individuals,
but most divers and snorkelers do not feel anything upon contact
with their tentacles.
