hunting quizzes
Hey, guys, can you think of something that makes an animal can stretch 1 ½ times its original size, is incredibly lightweight, and is stronger than steel? The answer is the spider silk!
Spiders are amazing animals. Although there is a plant species of spider we know, most spiders are deadly predators. They feed on the stem at its eight legs, and when they catch an insect juicy, that wraps it in silk, drill with his tusks, and the pump full of deadly poison. The poison paralyzes the prey, the spider uses a special digestive fluid, such as stomach acid, in turn inside the insect into a liquid that the spider may suck as a snack!
Most spiders have four pairs of eyes – two large eyes and six small eyes – that spot used to help their prey. Jumping spiders leap to their prey, and can jump up to 50 times its body length! That would be like to jump about 76 meters or 250 feet!
Spiders Trapdoor dig a hole in the ground and then cover with a lid on a hinge of spider silk. They hide inside the hole, and when an unsuspecting insect travels with them, jump and catch it!
But one of the most amazing and interesting facts about spiders is that you can turn a network of sticky threads to trap prey. When a insect is trapped in a net, the vibrations of the trapped insect to send a message through the spider web to tell exactly where to find the intruder.
Spider silk is incredible. If you make a thin steel cable like a thread of spider silk, spider silk is stronger. The steel under SNAP pressure, but the spider silk can stretch up to 1 ½ times its size, and so light it if the spider silk stretched on a chain long enough to wrap around the entire Earth would weigh only 450 grams in weight!
However, the silk is not only used for hunting. Baby spiders not sticky silk in a parachute that allows you to drift around the wind. The spiders stick to their webs with a silk dragline chain, that the catch if they fall like a rubber band. You can even make a rigid, tough silk to wrap a bag of eggs, which hatch in thousands of baby spiders.
Here are some of the most interesting about spiders:
The Goliath bird-eating tarantula sounds scary, but is quite harmless to humans. In fact, a tarantula bite is almost as bad as a bee sting. However, this spider is the largest in the world – the size of a dinner plate! He can shoot sharp, his hair irritation body everything it thinks is a danger (including humans), whistling a threat so powerful that can be heard 15 feet away, and can eat anything from beetles to frogs, small snakes, lizards, bats, and even up in the nests of birds to catch baby!
The smallest spider in the world is almost impossible to detect. Digua called Patu, Borneo, and is so small at 0.37 mm that would easily fit on the head of a pin!
The most poisonous spider in the world actually has a Guinness World Record. The Brazilian wandering spider venom so dangerous that a small drop, only 0,006 mg, is enough to kill a mouse!
