Giant “Mushroom-Cap” Jellyfish Spotted on Sanibel & Nearby Beaches
(Originally reported Mar 8–11 2024 — a favorite Sanibel sighting)
Mushroom-cap jellyfish (Rhopilema verrilli)
Beachgoers from Marco Island up through Fort Myers Beach and Sanibel reported unusually large, translucent jellyfish washing ashore — identified by local researchers as mushroom-cap jellyfish. These gentle giants can grow close to 20 inches across and feel like a wobbling bowl of Jell-O. Experts say they’re uncommon visitors here; wind and currents likely ferried them in. Their sting is typically mild, but for safety, admire with eyes — not hands — and let the tide do the rescuing.
Arthur’s take: “A jelly as grand as a teacup saucer! If you spot one, give it space and scan nearby shell lines — when the sea delivers surprises, it often leaves tiny treasures too.”
