Play Swimming Animation when in water. (ERROR CS0120)

So i've made a swimming script, that works fine. But i wan't to add, so when I'm in the water, it plays a swimming animation. I've made the animation, and put it into a script, but it says error CS0120: An object reference is required to access non-static member 'Unity.Engine.Play()'

NOTE I'm very new to scripting, just learning a little day by day how to do this and that. So i've probaly forgot to put something in the code. But here's the code:

using UnityEngine; using System.Collections;

public class Swimming : MonoBehaviour {

 //under water for (useless atm)
 void Start () {
     RenderSettings.fog = false;
     RenderSettings.fogColor = new Color (0.2f, 0.4f, 0.8f, 0.5f); 
     RenderSettings.fogDensity = 0.04f;

 }
 
 bool IsUnderwater()
 {
     return gameObject.transform.position.y < 3.9;
     
 }

     //swimming script
 void Update () {
     if (this.transform.position.y < 3.9) 
         {
         this.gameObject.transform.position = new Vector3 (transform.position.x, 3.9f, transform.position.z);
         RenderSettings.fog = IsUnderwater ();
         //animation V
         Animation.Play("SwimmingAnimation");
     }
 }

}

Everything else than the swimminganimation works.

Thanks :)
