I captured several toads yesterday, the largest of which filled my hands with about 8 oz of urine. It turns out not to be poisonous to people.
But I was ill for much of the night for some reason. I had spent the night eating crabs (and drinking beer, which is perhaps why I ended up capturing toads) and cleaning the crabs off course ravaged my hands. Perhaps toad urine is dangerous to crab injured hands? I sense a scientific study.
