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. Seee {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}.
Note: Spiders are divided into two principal groups: the
Dipneumona, having two lungs: and the Tetrapneumona,
having four lungs. See {Mygale}. The former group
includes several tribes; as, the jumping spiders (see
{Saltigrad[ae]}), the wolf spiders, or {Citigrad[ae]}
(see under {Wolf}), the crab spiders, or
{Laterigrad[ae]} (see under {Crab}), the garden, or
geometric, spiders, or {Orbitell[ae]} (see under
{Geometrical}, and {Garden}), and others. See {Bird
spider}, under {Bird}, {Grass spider}, under {Grass},
{House spider}, under {House}, {Silk spider}, under
{Silk}.
2. (Zo["o]l.) Any one of various other arachnids resembling
the true spiders, especially certain mites, as the red
spider (see under {Red}).
3. An iron pan with a long handle, used as a kitchen utensil
in frying food. Originally, it had long legs, and was used
over coals on the hearth.
4. A trevet to support pans or pots over a fire.
