when did the last northern white rhino die
Sudan (rhinoceros) Sudan (1973 – 19 March 2018) was a captive northern white rhinoceros (Ceratotherium simum cottoni) who lived at the Dvůr Králové Zoo in the Czech Republic from 1975[3] to 2009, and the rest of his life at the Ol Pejeta Conservancy in Laikipia, Kenya.[4] At the time of his death, he was one of only three living northern white rhinoceroses in the world, and the last known male of his subspecies. Sudan was euthanised on 19 March 2018, after suffering from "age-related complications".[5]
Rhinorrhea Rhinorrhea is characterized by an excess amount of mucus produced by the mucous membranes that line the nasal cavities. The membranes create mucus faster than it can be processed, causing a backup of mucus in the nasal cavities. As the cavity fills up, it blocks off the air passageway, causing difficulty breathing through the nose. Air caught in nasal cavities, namely the sinus cavities, cannot be released and the resulting pressure may cause a headache or facial pain. If the sinus passage remains blocked, there is a chance that sinusitis may result.[4] If the mucus backs up through the Eustachian tube, it may result in ear pain or an ear infection. Excess mucus accumulating in the throat or back of the nose may cause a post-nasal drip, resulting in a sore throat or coughing.[4] Additional symptoms include sneezing, nosebleeds, and nasal discharge.[5]
