Many (most?) of the animals that live in the intertidal zone hang out on the underside of rocks, or when the tide goes out, under stones. So I flip stones to find the crabs and the whelks and all the myriad scrambling creatures. Or I kneel and prop myself on my elbows to look for starfish under the big rocks.
Sometimes, I can't get down far enough. Then I shove the camera under the rock and take blind photos; you never know what's under there!

|Another shot, closer to the rock above. Barnacles, periwinkle (and I'm pretty sure the second from the top has a hermit inside). And those orange and white balls. What are they?|
|Cropped and zoomed in.|
So what are those orange and white balls? Eggs of some critter? And the white one with a hole would be one that's hatched? I checked Buzz's collection of eggs; scroll down to three photos that look like a match.

Or they could be whelk eggs, except they're too perfectly round. Herring roe is due about now, but it's cream coloured, and comes in with the tide.
