A California Least Tern with a fish the size of a canned sardine in its beak might very well have caught a Topsmelt. The two-toned body of this little fish is distinctive: the bright green on its back forms a clean line against its silvery sides and belly. Like California killifish, Topsmelt can live in both fresh and salty water. They are an important source of food for many seabirds.
