What type of worm is black with reddish orange spikes on it back?

I'm not sure if what you are looking at is a worm per se. It sounds more like a caterpillar which is the larvae of either a butterfly or moth. Try looking up different types of caterpillars since they tend to be quite colorful and can have hairs that stand out on various areas of their segmented bodies. That sounds kind of like a wooly bear caterpillar to me. wooly bears are often black with redish fuzz and black fuzz. (3 stripes) They become Isabella moths.
