Spider facts Spider facts Spiders construct webs, miraculously beautiful, glistening like polished platinum, a masterpiece of art with a 'come hither' charm. Spiderlings are baby spiders that hatch from silk covered egg sacs. Each kind of spider knows how to spin a certain pattern of a web when it hatches. Spiders have eight eyes, eight legs, two body parts, outside skeletons, and fangs. They do not have antennas or wings.
Males are smaller than the females.
The spider begins spinning its web in the evening or early morning before the flying insects get air-borne. The web-building spiders have two or more pairs of glands, called spinnerets, in their abdomens that produce liquid silk. Each spinneret has many small tubes. The spider spins a watery fluid. As soon as it hits the air it becomes hard.
