Anyone who’s been to the North American Atlantic coast has seen jingle shells - sometimes called mermaids’ toenails. But did you realize they’re from bivalve snails, like clams? You may even have seen the bottom half, with their keyhole where the byssus, sticky hairs, extrudes to hold them down.

these are Anomia, probably A. ephippium, which are true bivalves, not snails! they *are* extremely cool 🥰

I have an entire box of these I planned on making into something but I had no idea what they were! Thank you!!
