Narceus americanus (American giant millipede)
I thought I’d post a second photograph from our walk on the Billy Goat Trail. This is an American giant millipede (Narceus americanus, also called an iron worm) and it really is quite large, about four inches long. We saw a few of them and they are fairly common.
These millipedes do not have venomous stingers or fangs and are not dangerous to humans. They can secrete bad-smelling and bad-tasting chemicals from pores in the sides of their bodies. These chemicals help keep many predators away.
