The Waccamaw silverside (''Menidia extensa'') is a rare species of fish in the family Atherinopsidae. It is a federally listed threatened species of the United States. ==Description== This is a small (growing to about 2.5 inches), slim, almost transparent fish with a silvery stripe along each side. Its body is laterally compressed, the eyes are large, and the jaw is sharply angled upward. This fish spawns from April through June, but spawning reaches its peak when water temperatures are between 68 and 72 Fahrenheit. Fully developed larvae form small isolated schools by early May. No parental care of the young has been noted. The silversides reach sexual maturity by the following spring, spawn, and then shortly thereafter most of the adults die off. A few may survive a second winter.
