Separating parts of an object Is it possible to ungroup an imported Wavefront(.obj) object? I have created the object in EasyToy and would like to finish it with Blender due to it's better functionality.

The object looks like this: 



But I can't select just for example an ear or eyeball. So my question is: is it possible to do this or do I have to select the single parts by selecting faces, edges etc.?
In Edit Mode unselect all by pressing A.

Select a vertex from one part of the mesh and press Ctrl+L to select linked.

Then you can press P to separate that part of the mesh into a new object, you then have the option to separate the elements by selection, material or loose parts.
