Sesarmidae is a family
of crab
s, previously included in the Grapsidae
by many authors. Several species, namely in Geosesarma
, Metopaulias
and Sesarma
, are true terrestrial crabs. They do not need to return to the sea even for breeding.
The genera
Chiromantes, Parasesarma, Pseudosesarma and Sesarmops are apparently not monophyletic. Scandarma may be a junior synonym of some other genus.
Family (biology)
