Deadly spiders

[Music] almost all over the world from the poles to the equator there are millions and millions of spiders legend makes the spider a villain remember the nursery rhyme about Little Miss Muffet who sat on a tuffet eating her curds and whey along came a spider and sat down beside her and frightened Miss Muffet away generally we need not be frightened of spiders this large huntsman spider is harmless to us it eats insects and other small animals many spiders spin webs to trap their food this black house spider has caught a grasshopper it wraps it in silk and then poisons it this is a model spider inside the heads of most spiders are poison sex tubes carry venom to the fangs and these are the fangs in most spiders they close like pincers spiders have eight legs they are not insects insects have only six legs and are a separate group tics have eight legs they belong to the spider group so do scorpions they have eight legs this dangerous Black Widow from America has a red hourglass underneath its abdomen there are venomous spiders in every continent spiders of the same family are found all over Africa in southern Europe in Asia and in New Zealand there is a similar kind in Australia the Redback spider it lives in gardens and in rubbish dumps and especially in old tins it is quite small usually its body is about the size of a pea it looks like the Black Widow but has a red streak or spot on its back it is very glossy sometimes it is found in out houses it often lives right under the toilet seat so do take care the red back is dangerous if you live where he's found be careful when touching tins and blogs if you are bitten tire cord between the bite and the heart tighten it to stop the poisoned blood circulating clean the bite cut the bite and press out the blood and get to a doctor at once but the most deadly spider in the world lives in Australia and is found only in a small area near Sydney mainly north of the harbour it is found nowhere else its natural home is in holes in the ground and hollow trees but it also comes in two suburban districts into gardens and even into houses Jonah saw one in his garden a deadly funnel web spider so he called his dead and he came out with a stick he soon found a funnel web spider near a rock he decided to have a good look at her before he killed her she was nearly 2 inches long and black on top if anything comes near her she sits right up and raises her poison fangs she puts up her front legs to knock insects down and then she poisons them with her fangs her venom can be deadly even to a grown man she could not fight the stick so she ran away they will often pretend to be dead to deceive their enemies but they soon come to life if they see an insect Johnny's father wanted a closer look so he got her up on his stick her body is in two parts head and thorax and abdomen she hangs on tight to the stick with her eight legs Johnny was interested but a little afraid she can move freely upside-down and hangs on just as freely as if this was her normal position she can even hang on by the claws of one leg here is her abdomen the two spinnerets at the end of the abdomen eject liquid which turns at once into a strand of silk under the funnel web spiders head are the two long polished fangs they strike downward and do not pinch like the red backs fangs they're about a quarter inch long and carry the venom into the body of any animal it strikes as a rule spiders have a tires on top of their heads they also have two feelers which look very like legs in the frontal web area they may be anywhere so you have to be careful Johnny's father made a thorough search see what he found under an old tank a funnel web spiders nest in this case it's a tunnel in the ground line done tightly with web at the end is the egg chamber in which she lays her eggs she rears up angrily at being disturbed and then she settles down again here you see her abdomen and combined head and thorax sometimes they come into the hearse and get into a shoe waiting there and watching for insects spiders lurk in the dark look in your shoes before you put them on practice first aid just in case tie a ligature above the bite tighten it with a stick clean round the tiny wound cut it open and press out the blood get to a doctor at once most spiders are harmless they destroy insects these tunnels are made by harmless house spiders they're interesting to study you can tidy up webs without hurting the useful and harmless spiders always look at tins and rubbish before handling destroy any doubtful spiders on site especially if they look like funnel webs or have red markings like this red bag [Music]
