A radula is a chitin formation that's used to scrape food off of surfaces. It's a strip that's used essentialy like a single tooth of a grater. They get about as strong as the nail on your little finger, but not much more. I'd assume it would be safe to stick my dick in it.
So essentially, if you wanted that bitch to choke on you cock, you would put it in the hairy end.
I just looked it up and this post is wrong. It actually has rows of teeth. No need for alarm though, since you'd still be sticking it in the breather, not the mouth, as per
Can anyone tell how thick and long this critter is?
Why bother with some weird sea creature when you could get a dog?
