Ophthalmology of Afrotheria: Aardvarks, Hyraxes, Elephants, Manatees, and Relatives

  • Chapter
  • First Online:
Wild and Exotic Animal Ophthalmology

Abstract

Afrotheria is a unique and highly diverse clade of placental mammals. Their diversity is so great and morphologies so different that only by genomic analysis would one conceive phylogenetic relatedness. Once being a sequestered landmass, Africa diversified and species filled ecological niches through convergent evolution rather than gene flow: insectivores (elephant shrews, golden moles, tenrecs, and aardvarks), rodents (hyraxes), large herbivores (elephants), and aquatic mammals (manatees and dugongs).
