Gastrointestinal disease. [edit on Wikidata] Gastrointestinal diseases refer to diseases involving the gastrointestinal tract, namely the esophagus, stomach, small intestine, large intestine and rectum, and the accessory organs of digestion, the liver, gallbladder, and pancreas.
The only place where one can find an okapi is in the forests of northeastern Democratic Republic of Congo (DRC). Their range is limited by high montane forests to the east, a swamp forest below 500 m to the west, savanna to the north and woodland to the south.
Most of the information about the biology of the okapi is from captive animals. They are largely solitary and though once thought to be nocturnal, are now known to be active during the day. They feed largely on leaves, grasses, fruits and fungi, some of which are known to be poisonous.
