These two jellyfish were washed in on the high “spring” tide this morning. I flipped one over, and I think they are barrel jellyfish (aka dustbin lid jellyfish – although these were only about 16″ across).
The last few nights have seen the highest tides of the year – and it will be a few years before they are so high again. But, because the weather has been so gentle, the tides have done very little damage; hardly even altering the shoreline.
The term “spring” in spring tide comes from old northern European languages meaning to burst (like a pipe springs a leak). The opposite is the “neap” tide, which means pinched (like nip) or scanty.
