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.
How did the okapi, which stands over 5 feet tall and can weigh between 440 and 770 pounds, go undiscovered by scientists until 1901? The speciesâs preferred habitat played a big role in keeping it off the radar. Even today, scientists have a hard time locating or monitoring okapis because they live in dense, inhospitable forests.
