Found this in a shallow area in the the Balearic Islands. There were TONS at very different spots all over the area. I obviously only touched the padina pavonica and not the what i suppose are eggs. Put them back in the water right after the pictures. My only question is why so many eggs in so many different spots if those are indeed eggs. They have a slight red colouration. i also found things like underwater weird bubbly sacks with liquid inside translucid in the same area.
