Look at this thing - isn't he gorgeous? He's huge and has a really pretty pinkish-orange border on his body. He really does bury himself just like the small version but when he senses some good food has entered the tank he surfaces like a submarine and shows off his attractiveness. You can't tell from the pic but his shelll is a good 2". If you are placing an order with SWF.com I highly recommend you pick up one of these.... very cool!
