Peruvian Anchoveta Engraulis ringens
The distribution of this tiny, silvery relative of the herring depends on the yearly extent of the Peruvian Current.
This cold, deep current comes to the surface along the west coast of South America, bringing rich supplies of nutrients with it. Enormous shoals of anchoveta feed on the plankton blooms triggered by the increase in nutrients. The fish shoal within about 50 miles (80 km) of the coast, and many local people depend on them, as do many birds, including pelicans.
