Atherinops affinis

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.

Fun Fact:
The bright green band running down the silvery Topsmelt's back makes it easy to recognize.

What’s for Lunch:
Algae, larvae, and decaying organic matter

Where’s Home:
The ocean and the lagoon
