Not living in tunnels like Talpidae moles, the reader is not told how they manage to breathe. We assume perhaps that they take a breath at the surface and then hold it as they dive beneath. They couldn't get air in such collapsing soils without inhaling sand, so maybe they do like a dolphin or seal swimming throught the soil. We need to find the answer to this and put it in the article. Readers want to know if they have no tunnel, do they have to come up for air, or could they possibly do what Talpidae moles cannot: breathe underground without burrows?

I don't know much about them myself, and I think very little research has been done on them, but perhaps the sand is so porous that they can breathe through it. Ucucha 23:20, 10 April 2010 (UTC)
That's possible, I suppose. They must have some amazing nasal sand filters if that's the case. I'm sorry to hear that there may be reason to believe that this information is not knowable as maybe no one has figured it out and published it. However, it is another good idea for a thesis project brought to light by Wikipedia. Chrisrus (talk) 03:07, 19 July 2011 (UTC)
