and drinks up to 50 gallons of water daily.
Elephants must consume these giant quantities of food, due to their poor digestive
system. The small intestine is 82 feet long, the large intestine 21 feet long, and the
rectum adds a further 13 feet. The problem with the digestive tract lies in their gut;
elephants have too few symbiotic bacteria. These are the organisms which help break
down the cellulose of plant cell walls by producing enzymes called cellulases. The
most remarkable feature of the elephant's digestive system is its 5 feet long appendix,
bigger than the stomach. Proteins, starches, and sugars are digested in the appendix.
The elephant will excrete almost 200 pounds a day of semi-digested food.
Elephants live together in strong family units which might have as few as two or
