Laboratory of Recent Invertebrates
Sometimes I am reminded by gold lettering on a closed door that the museums are research institutions. This particular door always makes me wonder - maybe because I think of Gary Larson's boneless chicken ranch? However, the scientists going in and out all appear to have backbones. And part of a sign just inside the door says USKS from where I sit - the ending of Mollusks. So I gather that "recent" refers to time on a more geologic scale, and the invertebrates are the objects of study and not the principal investigators.
