Hydrothermal vent crabs feast on sea 'snow'
Article Abstract:
The crab Xenograpsus testudinatus lives at high densities around the sulphur-rich hydrothermal vents found in shallow waters off Taiwan, in an acidic environment that is low in nutrients. The issue of these crabs surviving in an adverse toxic environment is revealed as it is shown that these crabs swarm out of their crevices at slack water and feed on the vast numbers of zooplankton that are killed by the vents' sulphurous plumes, and that rain down like marine 'snow'.

A pneumo-hydrostatic skeleton in land crabs
Article Abstract:
Little water is available in the case of land crabs to provide a temporary hydrostatic skeleton before the new skeleton hardens and air does not provide the buoyancy necessary to support the animal. It is shown that whenever its exoskeleton is shed, the blackback landcrab Gecarcinus lateralis relies on an unconventional type of hydrostatic skeleton that uses both gas and liquid (a pneumo-hydrostat).
