spiders a more animated look than those of oth-

 pair often stouter than the others. They can

The crab spiders. The body is usually flat, 

 and wide behind. The front two pair of legs 

 are longer than the others, and so bent that the 

 spider can use them when in a narrow crack. 

 Some of them, like crabs, walk better sidewise 

 than forwards. Like the running and jumping 

 spiders, they make no webs for catching food.
