I have just seen the following pop up in my news feed.
Unfortunately the purseweb spider is not a tarantula. But it is the UK's only Mygalomorph this means their fangs, (chelicerae,) are positioned differently to other groups of arachnids. The technical speel is.. Mygalomorph have primitive orthognath position, with parallel fangs, whereas araneomorph have labidognath position, in which their fangs move side to side, like a pair of scissors. Mygalomorph's include tarantulas & trapdoor spiders.
The UK's Mygalomorph is Atypus affinis & it's small. With a body length of up to 15mm. (Half an inch.)
More details of Atypus affinis can be found on a pdf of a British Archaeological Society leaflet at.. Click Here.
Did you know that the UK is home to a tarantula? The purseweb spider. And now we've officially entered spider season, you might catch a glimpse of one. The purseweb spider is Britain's only tarantula and a member of the family that contains these 'tropical giants'.
