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.
Unlike spiders, the two parts of the body (cephalothorax and abdomen) of a harvestman are fused together into one part. They also have eight legs, feelers and mouth parts that work like a pair of scissors. Most species have short legs but some of them may have very long legs. Opiliones do not have any poison glands.
