Tiny blobs of protoplasm, jellyfish, washed up on the beach...
A decaying (and stinky!) harbour seal. Which recalls a few days earlier, walking along the breakwater in Victoria I overheard a little girl asking about a baby seal "sleeping" in the water, bobbing up and down. And the mother's explaining that, yes, it's gone to it's "forever sleep", which was kinda both touching and cheesy at the same time. My kids, I'd a told 'em "There's a baby seal that didn't listen to it's parents...".
