I wish I knew, to thank, deeply, those lovely people who pointed out and helped me recover the seahorse washed up on today's beach.
I've googled ... and it's exquisite little body is lying, now, on a bed of course salt, surounded by a moat of water (to deter ants, apparently)
What can I say? This is a cherished wee thing that few of us get to see except behind glass or onscreen.
