Animals simply don't cry. Or at least, they don't shed emotional tears. The only creatures who have evolved to do so, it turns out, are humans. We snivel at sad movies, well up at weddings and blink away hot tears of frustration during arguments.
If you define crying as expressing emotion, such as grief or joy, then the answer is yes. Animals do create tears, but only to lubricate their eyes, says Bryan Amaral, senior curator of the Smithsonian's National Zoo.
We often talk about the cry of animals, like wolves or eagles, but I assume you mean shedding tears. Lots of animals do this to clear debris from their eyes. But surprisingly, there's no good evidence that any of them do this as a sign of unhappiness (our close relatives, chimps and gorillas, use vocal noises).
While this may look superficially like emotional "crying", it occurs simply because elephants have lost the normal mammalian structures that drain excess moisture away from their eyes; without a true lacrimal structure, elephants are physically unable to produce emotional tears.

Giraffes are unable to cry as they do not have tear ducts, but many people have claimed to have seen them with tears.
Gorillas may cry out as vocalizations, but they actually don't produce tears like humans do when we cry. Gorillas produce tears in order to lubricate their eyes, but tear production as a form of distress is completely unique to humans within the primate species!
Cow cries before slaughter. They sense their final destiny. Don't be a reason behind their suffering.
Bonobos Cry Like Human Babies When Attacked to Get Comforted: Scientists. Bonobos produce high-pitched "baby-like" cries when they are attacked - to attract comfort from others, reveals new research. The displays of distress are strategic, increasing their chances of consolation from other apes, say scientists.
They all have unique personalities and their intellect has been noted as equal to that of a human toddler. They are highly emotional creatures and cry real tears when they are sad. Pigs are also extremely social and develop close bonds to their owners and companions.
Cats don't cry tears when they're sad or in pain. But Halls says whether your cat is experiencing emotional or physical pain, they'll exhibit behavioral changes that could include vocal crying. The sound of a cat crying is typically longer in duration and lower in frequency than day-to-day cat chatter.
Dogs can cry in one of two ways: vocally, in a way that tugs at our heartstrings, and with tears. When it comes to those sad-sounding noises, your pooch is most likely trying to express excitement, frustration, anxiety or pain.
Animal rights activists had, in response, dubbed Arturo the "world's saddest animal" and promoted a petition to have him moved to Assiniboine Park Zoo, a zoo in Winnipeg, Manitoba, Canada. The petition was created by Laura Morales of Hamilton, Ontario.
For example insects, arachnids and crustaceans don't feel any type of emotion. They don't show any signs of fear or pain. This is just down to the fact that their brain is too simple to hold this information.
Yes, it's true. Animals cry. A couple of years ago, zoologists which are people who study animals and their behavior, discovered that some animals, when they feel pain, scared or sad, also cry… like human beings.
"Pigs are at least as cognitively aware as a monkey," said Marino, commenting on a video of a slaughterhouse in Australia. The high-pitched squeals, she said, are "distress calls." Pigs have individual personalities, Marino said. They're also one of the few species that can recognize themselves in a mirror.
They dislike the smells of dung and saliva, so when housed, their feeding area needs to be kept clean and smell fresh, not contaminated with dung, saliva or exudate from other cows' noses.
They were stressed, petrified and piled up on top of each other. While waiting to be killed, the animals screamed in agony as they wounded themselves on the metal gratings. When animals are slaughtered, they are not completely stunned and are still aware of what is happening.
Elephants form strong family groups with immense memories and they cry when they are hurt (both physically and emotionally).
Evolutionary scientists believe that humans developed emotional crying to serve a social function. These theorists suggest that crying provides a visual (and sometimes auditory) signal to nearby people that you are in need of social support and nurturing (Bylsma et al., 2018).
In the same way newborn humans can cry as soon as they're born, common marmoset monkeys (Callithrix jacchus) produce contact calls to seek attention from their caregivers. Those vocalizations are not improv, researchers report in a preprint posted April 14 at bioRxiv.
We cry to protect our eyes, to wash out irritants and because, well, we are moved to tears. “There are three types of tears: basal tears, emotional tears and reflex tears,” explains David Silverstone, M.D., a professor of ophthalmology at the Yale School of Medicine.
Giraffes give birth standing up
Newborn giraffes enter the world in a sort of 'superman' position: front legs and head first, followed by their body, and then back legs. Because of the extreme size of their offspring, giraffe mums give birth standing up so as to not damage their babies' lengthy necks.
There are many instances of birds expressing grief and even engaging in mourning rituals, showing that sadness isn't just a human state. It's interesting to note that birds exhibit many of the grieving behaviors we do: their posture droops, they appear listless, and often cry real tears.
