MEGA RETURNS: Remember Mega, the mysterious “megamouth” shark caught in a fisherman’s net off Dana Point two years ago? . . . He returns Sunday at 6 p.m. in “Shark Encounters” on the National Geographic Explorer cable TV show. Mega--16 feet long with a mouth three feet wide--was the first megamouth to be studied alive, filmed for TV and then released. . . . Producer Michael deGruy recalls filming Mega underwater: “He didn’t object in the least as I touched his huge soft jaws.”
