For a group of San Diego whale watchers on Tuesday, the highlight did not involve whales or dolphins, but a bizarre-looking Mola mola.
The surprise encounter occurred 10 miles southwest of Mission Bay as Capt. Domenic Biagini, of Gone Whale Watching San Diego, was searching for cetaceans.
The Mola mola, or ocean sunfish, stood out because of its immense size and pale coloration as it lolled beneath the surface.
“It was really neat because most of the people on the boat specialized in diving, so this whole trip was something different for them,” Biagini said. “Right as they got on the boat they asked about molas, and I explained how we haven’t seen that many this year. So for this to have happened on this specific trip made it that much more special.”
Mola molas are the world’s largest bony fishes (these do not include sharks or rays) and can measure up to 14 feet and weigh 5,000 pounds. They inhabit tropical and temperate seas and feed primarily on sea jellies, squid, small fish, and crustaceans.
Because of their truncated bodies, the position of their fins, and their odd-shaped mouths, their appearance is otherworldly. Or, as the Monterey Bay Aquarium states on its website, “Ocean sunfish, or molas, look like the invention of a mad scientist.”
Biagini said most Mola molas encountered off Southern California measure 2 to 3 feet, but the sunfish that swam around his boat for 10 minutes on Tuesday measured at least 7 feet.
“It was by far the largest I’ve ever seen,” he said.
The divers on the boat were so impressed that some were tempted to jump in for a swim with the docile critter. “It was hard keeping them in the boat,” Biagini joked. “But everyone behaved.”
