If you visit the Fitzgerald Marine Reserve out on the San Mateo County Coastside right now, no matter the tidal conditions, a moving feature there involves harbor seals. They tend to gather in that area to care for their pups. Which means that hungry sharks must be lurking nearby. They are natural predators and much-feared by the seals. But, on several recent excursions to the Moss Beach locale, we did not spot a single, tell-tale fin inside the extended reef line. Apparently, though seals gambol there with impunity, it's too tough for the sharks to maneuver in those relatively shallow waters. If they could, mercy, the dining opportunities would be many and readily available. Can you say "seafood buffet?"
