Stomach Vary in the Animal Kingdom

Everybody knows that humans have only one stomach which is apart of the digestive system however, it is not the same for certain animals.  For example, cows, giraffes, deer, and countless more animals have stomachs with multiple compartments as a result they have four chambered stomachs which help them with their digestion.  While other animals such as seahorses have a different digestive root, the food goes straight from their esophagus to their intestines.  I choose this topic because until now I thought every animal had one stomach.  After reading this article, I wonder how animals similar to seahorses break down their food?
