Look At This?

When we were came home from renting some movies at BB, hubby and I found something on our porch, he said I stepped on it but he was never sure if I really did so. It was a slug, a leopard slug kind which normally grew up to 3 to 4 inches, since its skin looks like of leopards! I thought it was a worm, though, I never seen like this kind of insect before but it looks like a snail to me the difference is it has no shell. I thought it was a blood sucker leech ("LIN TA") but it wasn't. It looks so weird and it really gross me out! Yikes! And hubby took some of its pictures! Since it was the biggest slug he ever seen, he said they were usually 6 to 8 mm, but this one is a lot bigger than he thought. Well, just wanted to share how aggregated it is! sorry guys! LOL!
