In honor of the beautiful, wonderful, amazing, & endangered five remaining Species of Rhino’s on the Earth.
This is Emy, a Sumatran Rhino. I photographed her a few years before her death #CincinnatiZoo. Emy was the first #SumatranRhino to give birth in captivity in 112 years.
The Rhinocerotoids diverged from other perissodactyls by the early #Eocene. Fossils of #Hyrachyuseximus found in North America date to this period. This small hornless ancestor resembled a tapir or small horse more than a rhino. Three families, sometimes grouped together as the superfamily Rhinocerotoidea, evolved in the late Eocene, namely the Hyracodontidae, Amynodontidae and Rhinocerotidae. The #rhinos increased their range from Africa and mainland Asia as far east as #Borneo when the sea levels dropped.
German biologist Johann Gotthelf Fischer von Waldheim was the first to a scientific description of the Asian two-horned or Sumatran rhinoceros (Dicerorhinus sumatrensis) in 1814. At the time, the species could be found from as far away as Assam in northeastern India, south through mainland Asia and peninsular Malaysia, onto the islands of Borneo and Sumatra. Three subspecies were ultimately recognized, lasiotis in the north, harrisoni on the island of Borneo, and sumatrensis itself found in Peninsula Malaysia and on Sumatra. The species probably once numbered in the tens of thousands across these countries, but centuries of hunting and habitat loss drastically reduced its populations to small fragments. The northern subspecies, lasiotis, is now extinct. There is now a chance that some animals may survive on mainland Asia, but certainly any relict populations cannot be considered viable, including the few animals that somehow have managed to hang on by a thread in Borneo. The estimated population of such rhinos in the wild is no more than 100 in the current age, a hearkening call to the state of endangered species throughout the world. @robertclarkphoto @thephotosociety @instituteArtist” via @PhotoRepost_app
