Hermit crabs socialize to evict their neighbors
A UC Berkeley study of terrestrial hermit crabs in Costa Rica suggests that they socialize - unlike solitary marine hermit crabs - in order to steal shells from one another. Land crabs remodel and expand their shells, but to move up as they get larger, they must gather around other crabs to find someone to evict. Typically, crabs line up so that, once one crab is wrenched from its home, everyone can simultaneously acquire a larger abode. (2012-10-26)

Injuries among Dungeness crab fishermen examined in new OSU study

The grant will be used to conduct research critical to the sustainable management of the species. (2003-11-21)

Horseshoe Crab Research Center provides information to improve management
Mmanagement of the horseshoe crab population has become increasingly controversial. Fishermen catch horseshoe crabs for use as bait in the lucrative eel and conch fishery. Biomedical companies catch and bleed horseshoe crabs to produce a chemical (LAL) used to detect bacteria in injectable drugs and implantable devices. Environmentalists are concerned because shorebirds depend on horseshoe crab eggs to fuel their migration. Effective managment requires an understanding of all three dimensions. That is the goal of the new Horseshoe Crab Research Center. (2001-10-25)
