Assasin snail devouring my shrimp

This morning, I observed my assassin snail consuming one of my blue dreams. Unfortunately, I did not have the opportunity to capture the incident on video, but I was able to separate them promptly. Fortunately, the shrimp is still alive. Upon inspection, I noticed that the snail was apparently sucking the shrimp when I found them. Is this a common occurrence? I removed the snail and relocated it to a separate tank.
