Anyway, found the nudibranch in amongst sea rubbish. Every time we go to the beach we collect rubbish from the sea before we swim.
Twice found $5 notes, but not that day, often parking tickets & empty bait bags & a few unmentionable items, but only after putting the rubbish in a bag. Obviously not observant enough for the money!
Found the nudibranch in amongst everything on the water. This species is blue because they eat bluebottles & use the poison for their own protection (if I could only do similar in my home, better not elaborate).
Put it back amongst the non plastic material on the water.
Bag of rubbish, often use a bag found in the water. Not actually much rubbish that day. It's the tiny pieces of plastic which are the hardest to collect of which there is so much.
