Spiders
Some people treasure spiders as pets, while others get creeped out by them. Spiders are spread all over the world both in open nature and in our homes. There are thousands of species, some more venomous than others, to the point that they can kill a man in a matter of minutes. All spiders create silk and design complex webs in which they catch their prey, climb and lay eggs, despite their incredible diversity.
All spiders depend on their venom for survival. Spiders hunt and defend themselves using their venom. Only about two hundred actually represent a threat to human health from the many thousands species. They have adapted to the harshest of environments from the desert and the tropics to the Arctic areas where they can live underwater, which makes these creatures incredible.
The general myth people know in terms of gender relationships is that male spiders are famous for being killed right after intercourse. The male spiders which are relatively smaller than the females are in certain exotic species sacrificed for the perpetuation of their breed. Nevertheless, this is not a general rule as in most cases, both males and females survive the encounter.
Spiders use great camouflage, and they even imitate other species for survival, which allows them to adapt well to various living conditions. Most species have six or eight eyes disposed in various groupings on the body. More specialized than the others are certain eyes, not to mention the fact that there are also blind eye pairs that are located in various places on the articulate bodies of these creatures.
Webs are the distinct mark of spiders, but even these have a particular imprint of their own: thus, some create sheet webs, others spiral webs, not to mention the true mazes that some dangerous species design as deadly traps for their prey. A clear example here is the distinct tangled web the black widow makes. Yet, spiders also create webs for the protection of their nests. Placed above their home, webs lower the vulnerability of spiders from aerial predators.
There are other spiders which do not depend on webs for survival, and one famous example of such a species is the giant tarantula. Though they can produce silk threads, they are however hunting their prey down by using the ambush method. Extremely venomous and dangerous, tarantulas often make great pets for spiders lovers. So, don’t be surprised if you see such a hairy creature in a friend’s aquarium.
