Carnivores have a shorter alimentary canal because meat is easier to digest and contains more nutrients compared to plants. The digestive process for meat is quicker, and because many carnivores hunt for their food and need to be agile and fast, they do not require a large bulky digestive system like herbivores do. A shorter alimentary canal also allows for quicker food transit, reducing the chances of bacteria and toxins building up and causing harm. Additionally, carnivores tend to have sharper teeth and stronger jaws which allows for more efficient breakdown of food, reducing the need for a longer alimentary canal.
