Can a tortoise hiss or is this a sneeze?

[Donatello]

My russian Donatello was walking about in his enclosure and made a hissing like sound. Like if you were to breath hard out of your nose. It was a quick sound and as he did it he went back in his shell fast. My daughter was playing in the same room as i was looking at him and she made a loud noise when donatello did this. Maybe he was just startled?. He stays in my room, so usually the room is very quiet all day. Thanks.

One of my sulcatas does that when he gets startled or spooked and retracts into his shell. I have to be sure not to make any sudden movements around him.

Yes, it's them expelling air, like when they draw into their shells fast. Not really a hiss, but sounds like one. I'm not sure if they can really hiss too, but don't think so.

Ok thanks guys so much. I am taking him to the vet still for a check up because i got him from the pet store. Now that he is in a enclosure with so much substrate i wasnt able to find any poop. When i add water to it i look and look. The last three soaks their wasnt any poop either. But today there was some by his food dish. Does it look normal?
