These wandering spiders are pretty common at the FCRE. They have a very toxic bite but no one gets bit as they very rarely have any interaction with the people here. I am pretty sure, but not positive, that this is Phoneutria boliviensis, here eating a leaf-mimic katydid. A large, dangerous spider you would be best not to have run up your pants or such a thing.
