I work for a public aquarium in Monterey California, where we recently experienced the loss of one of our long time resident sea otters, Rosa. Rosa was a remarkable animal who contributed significantly and directly to ocean conservation via her role in various programs, including her nurturing of numerous young pups that were rehabilitated and released back to the wild. Her care takers are all avid puzzle doers, and this contributed to their collection of puzzles in their office cubicle.
