I have recently encountered this red thing on one of the beaches of east Sardinia. It was pretty close to the coast (around 20 meters) and has sticked to one of my fins.

Red creature

My question is: how is this creature called? Is it dangerous to have skin contact with it?

    $\begingroup$ How big is it? The perspective makes it hard to tell. (And I agree, very nice picture!) $\endgroup$

This appears to be an anemone, with the pedal disc towards the camera. I can't offer a positive ID, but would hazard a guess at genus Actinia.

Anemones sting, and the stings of anemones range from completely harmless to humans to highly toxic. In the absence of a positive ID, I would avoid poking it.

  • $\begingroup$ Thank you! Based on your answer, for me it is mostly similar to this one. Some of the photos here look very similar too, although I didn't see those blue dots near the tentacles. $\endgroup$
