Arachnids

It is commonly thought that spiders are part of the insect family but this misconception.For they are arachnids, another class of invertebrates.  Included in this class are  scorpions, spiders, daddy long legs, mites and other eight legged invertebrates.    

Scorpions and spiders are closely related ,though the appearance  may be deceiving .

There are over 1 million different speice of Arachnid that have already been discover and there is expected to be thousand more. I’m fascinated by these pre-historic looking invertebrate. There is still so much we don’t know about them but Aracnoligists are developing a  better understanding of them each day  it seems some people have phobias of arachnids but really we should admire them.

  1. Rene,
    Very informative post! I didn’t know that scientists estimated that there were that many undiscovered arachnids, extremely interesting! I really liked the pictures you added I thought that they added more detail to your post. Keep up the great blogging!

  2. Hello Rene,

    I was searching through your class blog for an entry in the 100WC when I saw you post on arachnids. I found it fascinating as they are one of my interests. I have some photos of spiders in my collection I have taken over the years. Some are quite beautiful but Australia does have its fair share of deadly types.

    Arachnophobia (fear of spiders) can be a big problem for some people. At times I was called to another class because a spider was found in the room. Rather than kill it, I would normally catch it and release it outside if it was harmless.

    The deadliest Australian spider I found was a female funnel-web. Its bite can kill if anti-venom isn’t given in time. Other nasties I have found are red-backed spider (something like the American black widow spider) and the more local white-tailed spider.

    I have been bitten by white-tailed spiders a couple times but I’m not sensitive to their bite so I merely felt a little itchy where bitten. For sensitive people, the bite can turn to a nasty sore.

    Despite the nastier spiders, imagine the world of insects if we didn’t have spiders to catch most of them. 🙂
