Wrapping around his right shoulder is a huge white piece of fur that resembles a boa. For some reason, there's always been a huge speculation about what it really is. Some say it is a boa , some claim it's actually his tail , while others have gone so far as to say that it's his armpit hair . Pretty bizarre if you ask me.

The Furry Wrap:
Yes, it seems there are some uses for the mysterious piece of fur that's constantly wrapped around his right shoulder. Apparently, he's able to manipulate it for many uses. He can curl and uncurl it at free will, as well as, make it grow in size in order to elevate him into the air and float away. The fur can sometimes be seen trailing behind him like a stream of cloud as he moves across the sky.
The fur can also be pretty strong as Sesshoumaru has used it to swat Inuyasha and the Tessaiga away like a fly. In one battle with Inuyasha, he had also used the fur to wrap around and squeeze Inuyasha as shown in the illustrated picture. Right after that scene, he basically unwrapped the fur and sent Inuyasha crashing away forcefully. So what else can it do? He's used it to sleep on and it looks quite comfy to me. :D (我也这么觉得,好想躺一下)
Unfortunately, we do not know for sure what it is though his fans are often bent on pinpointing it. There has been some speculations about what it is..and it seems the most popular conclusion is that it's his tail or some part of his dog form's fur . I've even heard a joke that it's his armpit hair. (= =)I sure hope that's not the case as it would be quite scary, especially if it's only growing out of his right arm. @_@;
