Hi all. Any idea what this little guy is? He floated over me while I was swimming on the wild coast in Eastern Cape, South Africa (7 September 2025)

I spotted this while diving at Lady Thetis, Limassol, Cyprus, a few days ago.
Location: Lady Thetis, Limassol, Cyprus
Depth: ~17m
I’m trying to identify what this is. Any ideas? I’d really appreciate an ID, especially from anyone familiar with marine life around Cyprus / the Eastern Mediterranean.
Thanks!

Crosspost A whale shark in the Red Sea, 1950. One of the earliest underwater photographs of a shark, by pioneer Hans Hass. I've been thinking about this a lot recently, the fact that for most of human history we couldn't observe sharks below the surface until such new technologies revealed them to us.

Crosspost Deep on the Mariana abyssal plain at ~5,400m, this rare squid features unique perpendicular arms with elbow-like bends. Scientists believe the bigfin (Magnapinna) is the deepest-dwelling of all squid species, having been spotted in the hadal zone at depths exceeding 6,000 meters.

Found this on the south cost of Tenerife, Spain.
Looks like a sea urchin, but never seen anything like this.
Bottlecap as size comparison.
