Since these were both eensy-weensy (maybe 1/4 inch? Fingertip for scale) I'm putting them together here. Red sponge dorids (Rostanga pulchra) like the one on the left are always this little. San Diego dorids (Diaulula sandiegensis) are usually >=1 inch when I see them! This one's a baaaaaby!

Good idea. Don't like to see private school in the headlines though. Boo, public money for private education
