Banana Slugs are common sight in California redwood forests, particularly after a rainstorm. They can be quite large, around half a foot or greater!
Got this identified by bugguide, its a little dark, but interesting nonetheless.. it was a new genus for Bugguide.
These weird millipedes are in the order Platydesmida and the family Andrognathidae
Wouldn't want to get bitten by this guy, even if it is only a pale shadow of the larger, tropical centipedes.
This is another large millipede in the family Xystodesmidae. I also found its natural predator, a Carabid beetle in the genus Promecognathus
These large Millipedes were common in the woods of New York my freshman year of college.
These things scare me. Very common in basements and houses in general, they are both fast-moving and creepy-looking
The warning colors on this beautiful Millipede warn off potential predators. Many millipedes contain cyanide as a defense mechanism, though the beetle Promecognathus laevissimus is apparently immune to it, though I don't know how.
