Black wildebeest
Black wildebeest act as hosts to a number of external and internal parasites. A study of the animal in Karroid Mountainveld (Eastern Cape Province, South Africa) revealed the presence of all the larval stages of the nasal bot flies "Oestrus variolosus" and "Gedoelstia hässleri". The first instar larvae of "G. hässleri" were found in large numbers on the dura mater of wildebeest calves, specially between June and August, and these later migrated to the nasal passages. Repeated outbreaks of mange (scab) have led to large-scale extinctions. The first study of the protozoa in blue and black wildebeest showed the presence of 23 protozoan species in the rumen, with "Diplodinium bubalidis" and "Ostracodinium damaliscus" common in all the animals.
Black-capped squirrel monkey
The black-capped squirrel monkey ("Saimiri boliviensis") is a South American squirrel monkey, found in Bolivia, Brazil and Peru. This South American monkey can be found in numerous zoos (with over 80 zoos keeping them in Europe alone, the majority of them being of the Bolivian subspecies) around the world, including the Ellen Trout Zoo, London Zoo, Apenheul Primate Park, Copenhagen Zoo and Auckland Zoo. Black capped squirrel monkeys are flexible omnivores, with diets including insects, fruits, flowers, eggs, and even small vertebrates (NeuroImage, Academic Press).
