[Gmsh] no tets in mesh saved as STL

I have generated a 3D mesh with Gmsh. If I check the saved 'test.msh' file, I find these element types:
1 (2-node line)
2 (3-node triangle)
4 (4-node tetrahedron)Next I saved the mesh (File->Save As) in STL format. In the 'test.stl' file I only find several blocks like
facet normal 0 -0.780942 -0.624604
vertex -4.06184 1.96854 12.1372
vertex -4.43697 2.07828 12
vertex -4.07973 2.07828 12
There are no other elements except for facets. Why don't I find any tets in the stl file?
In the Mesh module of Gmsh I have chosen '3D' to generate the mesh. I have also tried 'STL' with no better success. What is the difference?
If I cannot save the tetrahedral elements in the STL format, is there another format that I can select, which
1) saves the complete 3D mesh and which
2) can be opened in paraview or converted into the '*.vtk' format?
