Silverfish are sometimes mistaken for centipedes, which do inflict painful bites. One way to tell the difference is to note how many legs the bug has. Upon close inspection of a silverfish, youâll see that it only has six legs. o Silverfish are small insects (between 1/4 inch and 1/2 inch) and have shimmering, silver-colored scales.
The silver chub is a silvery minnow with large eyes. It has a small inferior (upper jaw overhangs lower jaw) mouth that is nearly horizontal. A small barbel is located at the back of the upper jaw. With the exception of a white band along the bottom margin of the lower lobe, the caudal (tail) fin is pigmented. As an adult, the silver chub averages 4 to 7 inches in length; however, fish as large as 8 or 9 inches have been found.
