FWIW & IMHO:
I believe that might be what is called a "Silverfish".
I do not know if that is a "slang" or actual name.
Ugly, though, and I don't know if I have ever seen one as big as that appears to be.
yup its a silverfish, I believe it is a centipede or type of centipede.
EDIT: I guess it's just a centipede, a silverfish looks like this
I have seen them and people have called them silverfish, and so do I, but I guess I was wrong.
Here is a picture of a house centipede ,looks like what you posted.
Silverfish. My wife had one crawl across her face in bed one night. Thank God for 24 Hour Home Depot. I had to go buy a gallon of bug spray and spray the whole house at 2 A.M. before she would let me go back to sleep. Creepy looking things, but I think they are harmless.
