I found this in the forest in 2004 when I went there with my big brother. I do not know the name of this special creature, it looks nasty. I think it should have some relation with the snail family, do you know what is this?

It's a slug, a name by many given to snails as well but slugs and snails aren't the same. I can't tell what species of slug it is, but well yeh, I guess if you'd want to know that some searching around for slug species could help out :).

I also think it is kind of slug, but after I check the online resource about the slug, I have not get any specie looks like this one. Maybe it can only be found in some complicate documentary. Thanks for you reply.
