[5] [6] Porcelain crabs can be distinguished from true crabs by the apparent number of walking legs (three instead of four pairs; the fourth pair is reduced and held against the carapace), and the long antennae originating on the front outside of the eyestalks.

The crabs can travel up to 1.46 km (0.91 mi) in a day, and up to 4 km (2.5 mi) in total. [4] Only a few land crabs, including certain Geosesarma species, have direct development (the mother carries the eggs until they have become tiny, fully developed crabs), and these do not need access to water to breed.

Telomerase is expressed by most vertebrates during embryonic stages but is generally absent from adult stages of life. [23] However, unlike vertebrates, lobsters express telomerase as adults through most tissue, which has been suggested to be related to their longevity. [24] [25] [26] Contrary to popular belief, lobsters are not immortal.
