Facts related to Spider
The world’s biggest spider is the goliath spider (Theraphosa blondi). It can grow up to 11 inches wide, and its fangs are up to one inch long. It hunts frogs, lizards, mice, and even small snakes and young birds. The world’s smallest spider is the Patu marplesi. It is so small that 10 of them could fit on the end of a pencil. Spiders do not have teeth, so they cannot chew their food. Instead, they inject digestive juices into the innards of their meal. Then the spider sucks up it innards. Spiders can’t fly, but they sometimes sail through the air on a line of silk, which is known as “ballooning.” Water spiders are the only spiders that spend their entire lives in water. The spiders construct a “diving bell” that allows them to live and spin webs underwater. They use their legs like a fishing pole to pull in insects, tadpoles, and even small fish. The silk that comes out of the spider’s spinneret is liquid, but it hardens as soon as it comes in contact with air. Some spiders have up to seven types of silk glands, each creating a different type of silk such as smooth, sticky, dry, or stretchy. The silk in a spider’s web is five times stronger than a strand of steel that is the same thickness. A web made of strands of spider silk as thick as a pencil could stop a Boeing 747 jumbo jet in flight. Scientists still cannot replicate the strength and elasticity of a spider’s silk.
The effects of a spider bite vary according to several factors, including the amount of venom injected and the size and age of the person who was bitten. Children and elderly people are especially susceptible.The most venomous spider in the world is the Brazilian Wandering Spider, or the banana spider. This aggressive spider wanders the forest floors of Central and South America looking for food. Just a small amount of venom is enough to kill a human.
