Nyeh, something that would really interest animal people out there. Came across it on 9gag ( which is one of my most viewed websites since Aqil introduced to me in Julian Hodge)
Its called a Deep Blue Slug (Glaucus Atlanticus), and it sorta reminded me of Kyogre, from Pokemon Sapphire!
and yeah, for real, it actually looks like that! Its amazing how these things are!
