Spider crab
Spider Spi"der, n.[OE. spi[thorn]re, fr. AS. spinnan to spin; -- so named from spinning its web; cf. D. spin a spider, G. spinne, Sw. spindel. See {Spin}.] 1. (Zo["o]l.) Any one of numerous species of arachnids comprising the order Araneina. Spiders have the mandibles converted into poison fangs, or falcers. The abdomen is large and not segmented, with two or three pairs of spinnerets near the end, by means of which they spin threads of silk to form cocoons, or nests, to protect their eggs and young. Many species spin also complex webs to entrap the insects upon which they prey. The eyes are usually eight in number (rarely six), and are situated on the back of the cephalothorax. See Illust. under {Araneina}. [1913 Webster]
