Question: do anchovies have fins and scales?
Answer: The lack of an adipose fin behind the dorsal is sufficient to separate anchovy from smelt at a glance, while the silversides (Menidia) have two dorsal fins instead of one. The anchovy has large, thin, easily detached scales and a deeply forked tail. ... The body is about 4 to 5 times as long as deep in both anchovies.
