I recently posted this photo of a whelk egg case:
Sometimes if you’re lucky you can rip open the casings and find tiny unhatched whelk babies. Usually when I try this I just find them to be filled with sand, but today I got lucky and snapped what may be my new favorite photo.
All together now: awwwwwwww! Incidentally, it is possible to tell which type of whelk the egg case is from by the case’s shape, but I can never remember which is which. Knobbed whelks are what’s most common here, so let’s go with that.
