The Spider's Silk
The Spider's Silk
Spider silk in general is remarkable for its strength and elasticity, but there are many different kinds, all with special properties, and each used for a specific purpose.
Spider Webs
Spider Webs
In its natural habitat each species builds its traps according to predetermined, inherited patterns. Whether the web is made by a newly-hatched spiderling or a full-grown spider, the design is the same. Only the size differs.
Trap-Door Spiders
Trap-Door Spiders
are so-named because of their habit of digging a burrow into the ground, which is lined with silk, and capping the burrow with a trap-door made from layers of silk and earth.
Common House Spider (Achaearanea tepidariorum)
Common House Spider (Achaearanea tepidariorum)
The house spider's webs are made of sticky strands that catch dust and other debris as easily as prey. These webs are commonly found in houses and are what most people refer to as cobwebs.
Black Widow (Latrodectus mactans)
Black Widow (Latrodectus mactans)
Despite its common name, a female black widow does not invariably eat the male after mating. In fact, it is actually fairly common for the male to live long enough to mate with several females.
Goliath Bird-Eating Spider (Theraphosa blondi)
Goliath Bird-Eating Spider (Theraphosa blondi)
Although it is easily large and powerful enough to catch them, and despite its name, the Goliath rarely eats birds, although it will eat hatchlings. Its usual diet consists of frogs, small snakes, beetles, insects, lizards, and even bats.
