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 Japanese spider crab has the greatest leg span of any arthropod, reaching 5.5 metres (18 ft) from claw to claw. The body may grow to a size of 40 cm or 16 in (carapace width) and the whole crab can weigh up to 19 kilograms (42 lb)âsecond only to the American lobster among all living arthropod species. The males have the longer chelipeds; females have much shorter chelipeds, which are shorter than the following pair of legs.
