Anybody know what the circle is?

Is it some sort on animal? Saw it while strolling along Paignton beach.
It was a fabulous retreat enjoyed it so much I have booked another 5 day solo retreat for next year. :-)

Looks like some sort of jelly fish? But it’s strange that it seems to be perfectly circular.
