The start of digestion
Just like humans, the Florida Crayfish has to digest its food. The reason humans digest is to break down starch into glucose. There are two types of digestion in the mouth mechanical and chemical. Nutrients are absorbed in the small intestine by small hairlike structures called villi. Water is absorbed in the large intestine. The absorbed glucose ends up in the liver, and is stored as glycogen until it is broken down and can be used for energy. Oxygen and glucose is converted into carbon dioxide and energy because of cellular respiration. When ATP turns into ADP molecule, energy is produced. Just like humans crayfish chews the food and the particles pass through the esophagus. It then enters the cardiac stomach and breaks down the particles more with enzymes to help. Dorsal abdominal artery removes nutrients through blood vessels and into bodily fluids. Contractions complete the food items digestion. [1]

How Crayfish obtain food
They may also grab and eat anything that is small and unwary enough to cross their path too closely.Mature crayfish are more active at night.
