Hi, Thanks for the message. Our spider - Vivian, was bought in a pet shop in Kent, UK, and given to a colleague of my husband, who did not want it, so it was brought home. The only thing we know is that she was venemous. She was very dark brown, with hairy legs her body and was about 2cm long, and including her legs she was about 4.5cm across. She had large, very shiny fangs.
She has two yellow marks underneath her abdomen. The only one I found on the internet that looks like her is a trap-door spider, but she never dug into the peat or tried to make a web of any kind. Unfortunately, it looks like she may have died during a stressful shedding, but I will be keeping her for another few days, as she seems to twitch every now and then, but I can't be sure.
Thanks for the interest.
