I am looking for examples of surfaces $M$ with gaussian curvature $K\lt0$ Additionally, a closed geodesic lies on the surface $M$

Thanks

See here, or here for examples. Also wikipedia gives examples. – Dietrich Burde Jan 05 '17 at 15:16
@DietrichBurde the links dont give an answer to the second part of my questions. There is a closed geodesic $\gamma $ on $M$ – XPenguen Jan 06 '17 at 20:38
