Just wondering how they fuel themselves. I realise Alduin eats souls but that's not very nutritious is it. Anyone know whether they're carnivorous, vegetarians or omnivore's?

Dragons are milk drinkers. Also I think they eat people.

The dentition suggests carnivorous. They don't appear to have the molars that a vegetarian or omnivorous species would need.

Hopefully their main prey is skeevers. I hate those creatures!

Soylent Green.

At least one of the dragon roosts(i dunno what they're called) had some dead animals laying about. There was a cow, a troll, and a deer I think.

Deer, Mammoths, Trolls and Nords based on some of the dragon roosts.

I rather wonder if they have to eat. They aren't mortal (unless someone kills them). I believe they don't have to eat, but rather do it for fun.

You find guard armor on the western watchtower dragon.
