I just took a pic of a spider at my workplace and I have no idea what kind it is or if it’s venomous or not. I have included a clear picture of it
This is an Orbweaver or Writing Spider in the genus Argiope, most likely the Banded Argiope, Argiope trifasciata. It looks like an immature individual and that is its exuvia or cast off exoskeleton at the top of the image, indicating that it has recently molted. Most spiders have venom, but that of the Orbweavers is not considered dangerous to humans. They are reluctant to bite people, though a large individual might bite if carelessly handled.
