CRAB SPIDERS' TRICKS FOR YELLOW CAMOUFLAGE
Journal of Experimental Biology, 2013Chameleons and octopuses may be famed for their extraordinary camouflage skills, but this ability is not unique and many animals, big and small, can match their surroundings. Perhaps one of the smallest is the tiny crab spider, Thomisus onustus , which measure between 1 and 10 mm.

Resource Underutilization in a Spider Crab Industry
Fisheries, 1977Abstract Underutilization in a spider crab fishery was large with respect to 1974 landings of 3300 metric tons (t). Potentially 1600 t were lost by not fishing all commercial stocks; at least 264 t were discarded in plants because they were too small, soft-shelled, or dead; an additional unmeasured quantity of small and soft-shelled crabs was discarded

COMMENSAL ASSOCIATION OF A SPIDER CRAB AND A MEDUSA
The Biological Bulletin, 1927During four successive years the writer was associated with a week-end biotal survey of the coast of South Carolina, and on two of these field studies encountered a curious commensal re lationship between a spider crab and a medusa. The animals con cerned were Libinia dubia Milne-Edwards and Stontolophus niele agris L.
