Sex dimorphism in size is especially marked in aquatic brachyurans than in semiterrestrial
and terrestrial ones (Pinheiro & Fransozo, 1999).
Armases angustipes (Dana, 1852) is a semiterrestrial
crab of the family Sesarmidae, and has a wide distribution.
Effects of salinity, temperature, and starvation on the larval development of Armases (=Sesarma) miersii (Rathbun, 1897), a semiterrestrial
crab with abbreviated development (Decapoda: Grapsidae).
In view of Armases' semiterrestrial
lifestyle in which it experiences soils that vary widely in water content and pore water salinity, its osmoregulatory abilities are likely excellent.
It is known that coloration patterns of semiterrestrial
crabs are related to growth, seasonality, desiccation, or endogenous rhythms (Reid et al.
Thus, like semiterrestrial
and high-intertidal crabs (e.
Cancrincolidae (Copepoda, Harpacticoida) associated with land crabs: a semiterrestrial
leaf of the ameirid tree.
The burrowing semiterrestrial
crab Neohelice granulata is found in the intertidal zone of estuaries, salt marches, and mangroves.
Visual cues are often important for courtship in semiterrestrial
species (Christy & Salmon 1984, Backwell et al.
Isopods of the semiterrestrial
oniscid species Ligia exotica, which live on the seashore among pilings, beach fortifications, jetties, and rocks, usually not more than a few meters from the water's edge, lead a rather different life from that of wholly terrestrial isopods such as pill bugs.
In southwestern Atlantic mangrove areas, the most studied semiterrestrial
burrowing crabs are the varunid Neohelice granulata (Dana, 1851), the grapsid Cyrtograpsus angulatus Dana, 1851, and the ocypodids Uca uruguayensis Nobili, 1901, and Uca rapax (Smith, 1870).
