Elephants can cry
It's somewhat controversial to say elephants weep and laugh. Critics say we risk anthropomorphizing behaviors that may have other explanations. However, it seems that there's plenty of evidence that elephants do cry tears of emotion.
One such famous example is Raju, the elephant that cried when rescuers freed him from a life of torture. We reported last year, "The elephant has been forced to endure a life of painful shackles and handouts from tourists; mostly subsisting on plastic and paper for food. The rescue became even more emotional after Raju began crying while officials removed his bonds."
Discovery News writes, "[Raju's rescue] isn't the first time an elephant has been seen weeping after a traumatic event. Last year, a newborn elephant calf at Shendiaoshan Wild Animal Nature Reserve in eastern China reportedly cried inconsolably for five hours after being stomped on by his mother, which then rejected the little elephant. The calf, named Zhuang-zhuang, was later 'adopted' by a keeper, according to the news site Metro. Elephant tears, as for human ones, often appear linked to feelings of sorrow."
Marc Bekoff, emeritus professor at the University of Colorado, Boulder, writes in an opinion piece for LiveScience: "[W]hile scientists are not 100-percent certain, solid scientific research supports the view that elephants and other nonhuman animals weep as part of an emotional response... And, let's not forget that many 'surprises' have been discovered in the emotional lives of animals, including laughing rats and dogs and empathic chickens, mice and rats — all published in outstanding peer-reviewed professional journals."
