We went for a walk on the beach in Spanish River Park yesterday afternoon. I saw several of these washed up on shore.
You can’t really get that much scale from the sand and seaweed, but the body was about the size of my hand. I’ve heard they can get larger, but I’ve never seen any much bigger than this one around here.
It makes one a little nervous, walking barelegged through the surf, because the surging waters could deliver one unto your legs and wrap the tentacles around them without your even being able to see it coming. Fortunately, there were no incidents. This one was still alive, but probably not for long. And I wasn’t going to try to pick it up and toss it back. Particularly given the almost certain futility of it.
