Wildebeest of her own, "Nelly Gnu and Daddy Too". Wildebeest Wildebeests, also called gnus, are antelopes in the genus Connochaetes. They belong to the family Bovidae, which includes antelopes, cattle, goats, sheep, and other even-toed horned ungulates. "Connochaetes" includes two species, both native to Africa: the black wildebeest or white-tailed gnu ("C. gnou"), and the blue wildebeest or brindled gnu ("C. taurinus"). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black
Blue wildebeest found to be hosts to 13 species of nematodes, one trematode, larvae of five oestrid flies, three species of lice, seven ixodid tick species, one mite, and the larvae of a tongue worm. Of these, most were more prevalent at some times of the year than others. Generally, the larvae of "Gedoelstica" and "Oestrus" occur in the nasal passages and respiratory cavities of the blue wildebeest, and sometimes migrate to the brain. Compared to some other bovids, blue wildebeest are resistant to infestations by several species of ticks. The blue wildebeest is mostly active during the morning and the late
