"Emperor tamarins were named after the Emperor of Germany, Emperor Wilhelm II, due to the long, droopy white mustache. Swiss zoologist Goeldi gave the species the name of "emperor" as a joke, however, the name stuck. Emperor tamarins have been known to live up to 20 years." http://www.patreon.com/raocow https://talkhaus.raocow.com/viewtopic.php?f=3&t=17447
