If you're looking for something powerful to pull on your line from the shore of the bays or surf, this might be the beast you're looking for. Bat rays have been given the name "mud marlin" by anglers to describe how strong of a fight they put up. Bat rays can be found in both San Diego Bay and Mission Bay, as well as along every sandy beach in the county. They can be caught on almost every dead bait, but have a particular interest in squid. But be sure you have the right tackle, they're capable of pulling a LOT of drag.
