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.
This very successful group of arthropods have four pair of walking legs (8 legs). The first pair of appendages are the chelicerae, and the second pair are pedipalps, appendages modified for sensory functions or for manipulating prey. They are mostly carnivorous (many mites are herbivores).
