I have attached a photo of what I believe to be a venomous Spiny Oak Slug Caterpillar. Please confirm. I live in a very dense mature climax Oak / Maple forest. This insect was sliding along the top of a leaf onto of my boat cover.

Yes, that is the spiny oak slug caterpillar. One of the more remarkable insects you will ever see.
