3d character takes 17 draw calls?

I have a penguin character on ios that is taking 17 draw calls even though there are only a few textures associated with it that I can find. What determines how many draw calls a model takes and how do I consolidate them so it only takes 1.

Thanks,

Separate meshes constitute to multiple drawcalls. Having multiple materials on a single mesh will lead to multiple drawcalls too. Multiple lights (with shadows) produce multiple drawcalls too, IIRC. All these factors multiply.
