Galice Hoarau won an 8 Day/7 Night & 12 Dives for 2pax at Meridian Dive Resort

During the dive, I noticed this sea snake (Hydrophis sp.) unusual behavior, at first rubbing on the sand in a vertical U, then forming a knot on itself with pieces of old skin hanging at the tail: it was shedding! Although sea snakes have been known to make these knots on themselves to help shedding their old skin, this behavior has rarely been captured on photo.
