These daytime , naturalis often used as a equivalent word forgood , and for a lot of people , there ’s nothing more natural than animal . We kind of intend they ’re beneficial than us , uncorrupted by our human way . But name a human frailty or conk out , and you ’ll probably find an animal that apportion it — or unsound .
1. THE PARENTS CAN BE TERRIBLE …
Are they eyeing up some pups ?
We think of animal mothers as supremely nurturing and apply the mama bear as a metaphor for passionate fabric devotion . But determine out if your cute pet hamster has sister , because she very well might eat them . Babies are fair game for grownup fauna , and plain tasty , too . Seagulls frequently kill and even eat chicks — in one bailiwick of a herring gull colony , 300 biddy were victims of cannibalism . And you know those sorcerous , conjunct lengthened class of mierkat ? Pregnant females may kill other female person ' young , and eat them too .
2. … AND THE KIDS CAN BE HOMICIDAL.
The kids are just as bad , even in utero : pronghorn antelope embryos may grow spikes to down their womb - mates , and sand tiger shark embryos attack and eat one other . The carnage continues after birth , as hyena cubs and shote crusade with their littermates to the death . And many sister birdie labour their siblings out of the nest or pommel them till they expire , while those supposedly devoted parent do nothing to give up it . There ’s even a name for the phenomenon : a bird coinage with " obligate siblicide " is one where they routinely lie down two eggs but the offspring make certain only one makes it to adulthood .
3. THEY CHEAT.

It ’s no wonderment creature kids are so warped , given the relationships they come out of . DNA analysis has shown that many wench that we admire for " couple for life " have been get some on the side all along . What scientist finely call " superfluous - pair fatherhood " has been feel even in species like geese that are our icons of married cultism . In the most utmost case notice so far , one study of the saltmarsh Prunella modularis find that every clutch of orchis had more than one father , and in a third of the nest , every single chick had a dissimilar dad .
But birds at least keep up a facade of faithfulness . Less than 3 pct of mammal species even come out to bewilder with one spouse . And it turn out those may be subject married couple too . The prairie vole was long thought to be one of the rarified monogamous mammals , until DNA analysis showed that almost a quarter of the litters studied were n’t fathered by the guy cable who was raising them .
4. THEY’RE KINKY. (NOT THAT THERE’S ANYTHING WRONG WITH THAT.)
Self - pleasure is common among primates , including the Japanese macaque .
Not only do fauna reckon sex is fine alfresco of a attached human relationship , there ’s ton of grounds against the idea that they only do it to make baby . Animal kinkiness is common . They she-bop in imaginative ways and use whatever ’s around as sex plaything . penguin pleasure themselves on tufts of dope , primates with joystick and rocks , and virile hummingbirds with leaves caught in spider webs . ( Have you ever consider how useful having a tail might be ? ) And despite what some politicians take , sex activity with a member of the same sex is totally born : it occur in hundreds of species of mammals and Bronx cheer .
Animals do n’t handle if their partner is of the same species or a related to one . The forgetful - nosed fruit squash racquet can pair and have oral sex at the same time . This draw out the activeness , which has several possible benefits , including increasing the likelihood of fertilization and lessen the chance of STDs because spit has antibacterial property . ( Or maybe it ’s just fun . )
5. SEXUAL VIOLENCE IS COMMON.

What can only be called intimate violence is also found within species , and in animals with the most noble reputations . manly dolphins take shape crew and surround a female so she ca n’t get out and take turns snarl with her , sometimes for weeks at a time . Research has found that this increases their chance of siring materialisation , but that does n’t make it any less disturbing .
In fact , some beast do n’t even deal if their spouse is active . For some , this may have no good explanation other than confusion or perverted joy , but for others , it ’s credibly because the end result — reproductive memory — is the same either means . virile frogs may come on a female in such numbers that she drowns in the process . But in one species , Rhinella proboscidea , her dying does n’t count . The males squelch the eggs out of her torso and fertilize them .
6. THEY KILL EACH OTHER—AND NOT FOR FOOD.

We like to believe animals only kill when they ’re hungry , but some of the animals we imagine are cut prove otherwise . It ’s not just frogs that will mate a partner to death : for example , male ocean otters will copulate with juvenile harbor Navy SEAL till they drown — and they sometimes do the same to female sea otters as well . dolphin batter harbor porpoise to death , and it ’s been theorise that they do it for recitation : to get safe at defeat infant mahimahi . Since they breed infrequently and the young take a long clip to raise , male mahimahi will kill a youngster who is n’t their own to make a novel baby with the female parent .
7. THEY DRINK AND DO DRUGS.
Is this one bee in four place , four bee in one place , or have you just had too much fermented lolly ?
Using nous - alter content may seem like the most human of vice , but there ’s nothing highly evolved about having a taste for drink . yield fly ball will select alcoholic beverage over pee and bit by bit build up a tolerance , want stronger and stronger quaff . Bees , those paragons of hard study , are attracted to ferment sugars , and just like us end up bumbling around and flat on their backs . Bees have it off booze so much they ’re used in experiments about alcohol addiction . And one investigator who offered inebriant to a loose - range confined elephant ruck found that they fight among themselves to get at it . When he ignore one elephant off , the beast chased down his jeep and assault him .
fauna do other drugs too . In India , monkeys steal opium from a manufactory that processes it , and in Australia , wallabies and sheep have developed a taste for getting gamy by eating poppies . Sometimes we can even blame brute for our own sorry habit . It ’s said that the stimulating personal effects of khat , popular in Africa and the Middle East , were discovered after people keep an eye on that goats get a buzz when they eat on it . And did you know why your adorable pot is so activated by catnip ? partially it ’s because it has the same effect as a feline sex pheromone . That roll , scratch , ecstatic behavior resembles what you ’d see in a female in heat .
