    Keyserling, 1877

    Cupiennius salei, commonly called the Tiger wandering spider, is a large spider belonging to a group of wandering spiders found in Central America (also one of many diverse types that mistakenly get called banana spiders[1]), although this species is specifically from Eastern Mexico, Guatemala, Belize and Honduras. The species was accidentally introduced into Germany in the early 20th century from banana plantations in Central America. In the mid-1950s it was realised that the spider is an ideal model for biological research because of its large size, inactive behaviour, and ease of breeding in laboratories. From an initial 1963 publication on its biological characteristics, it has become the most studied species of spider.[2][3] Furthermore, the spider is now known to produce a complex neurotoxic venom, such as cupiennins and CSTX, of which a peptide called CsTx-1 is highly potent for paralysing its prey.[4][5] Its toxin has also become one of the most studied among those of venomous spiders. As the spider does not produce a web for trapping prey, being venomous is its primary strategy for prey capture. It is known to prey on a wide range of insects and small vertebrates.

    "Mild bite"
    Bite/Sting Date:
    May 26, 2016
    Pain Level:
    • Moderate pain.
    Was rehousing a 1.5" individual, and if you've ever owned these you know they're extremely fast. Spider jumped out of vial and I scooped it up (gently of course) in my fist. Felt a pinprick like feeling, so knew I was bitten. Bite was on the first segment of my middle finger.
    Very tiny puncture marks, reddening and a little swelling.
    Mild pain lasted for about six hours. The bite was red and slightly swollen for just a few hours. After about a half hour, my arm became a bit tense. This lasted only a few hours.
    Medical Attention:
    No medical attention sought.
    Lingering effects:
    All symptoms disappeared after about eight hours. Bite occurred at about 11am and by 9pm I was able to sleep without any real discomfort.
    On Thursday May 26, I was rehousing my Ctenids and was working with a 2" C. salei. Being that they are lightning fast, it took me a while to do this. At one point the spider jumped from its vial and onto the floor. I gently coaxed the spider into my hand and made a fist. That was when I felt a prick on my middle finger. The only immediate symptom was a bit of pain at the site. Over time it became red and swollen, but with a diameter of maybe 5mm. About a half hour post bite, my arm felt a bit tense and cramped. This lasted for a few hours but I was able to go on with my day without seeking medical attention or taking Tylenol or other painkillers. All symptoms were gone for the most part by the end of the day, eight hours after the bite. Perhaps this would've been a more painful experience had the spider been fully mature. If I had to rank the pain on a 1 to 10 scale (4 being bee sting), I would rate this at a 3 or 4. So not too bad compared to other known Ctenids.
