They found something like this in the living stones :-) What a wonder? :-) For those who don't understand what’s in the picture, I'll explain: it's some kind of mollusk with small branched horns on its upper part, brown in color, it behaves like a rabbit, and it's unclear what it feeds on.

One of the forms of a nudibranch. Some species damage corals.
