The Aquarium of the Bay, that little Aquarium over by Pier 39, just got a new tenant: an almost-five-foot-long shovelnose guitarfish. It looks like an 80s hair-band bass, we suppose, like a Gibson Explorer Shadow, but anyhow, it's a female, and she'll be there for the duration. Photo by Steve Hewgley of a Monterey specimen.
