Spider :
The spider , also called a spider , is a kind of animal berbuku-book (arthropods) with two body segments , four pairs of legs , no wings and do not have a mouth cud. All
types of spiders classified into the order Araneae , and along
with the scorpion , scorpion , mite -eight-legged all
incorporated into the classroom arachnids . Field study of spider called arachnologi .
Spiders are predators ( carnivorous ),
sometimes even cannibals . Its main prey is insects . Almost all types of spiders, with the exception of about 150
species of the tribe Uloboridae and Holarchaeidae, and suborder
Mesothelae, able to inject able through a pair of
fangs to the enemy or prey. Nevertheless, tens of thousands
of existing species, only about 200 species that bites can be dangerous
to humans.
Not all spiders make webs to
catch prey, but all of them capable of producing yarns of silk -
which is a thin strand of fiber protein but strong - of the gland
(called a spinneret
) located at the back of his body. Silk fiber is
very useful to assist the movement of the spider, swinging from one
place to another, trapping prey, make a bag eggs , protecting the
nest hole, and others.
I think this spider is rare, because this spider is big and rarely
encountered, when i went in to the kitchen and put one of glass and found this predators ( carnivorous ).
