The long front legs of Crab Spiders and occasional sideways walk demonstrates their distant relationship to more familiar marine crabs.
Crab Spiders have front legs that are considerably longer than the others. Species in the Tmarus genus stretch them out in front of themselves while resting on branches and twigs. This position resembles that seen in Long-jawed Spiders. Tmarus spiders have brown mottled coloring that camouflages them. Crab Spiders are active hunters and do not spin webs to trap prey. Their ability to blend in with foliage makes it easier for them to capture unsuspecting, or oblivious, insect prey.
