One of the slap-up joys of science fiction is meet alien races , with their eldritch customs and immensely dissimilar biology . A really great foreign wash can make you oppugn everything you know about humanity — but sometimes , alien airstream do n’t alone make horse sense .
In particular , a lot of exotic mating rituals seem guaranteed to force back their races into extinguishing in no clip flat . Here are some alien race with extremely illogical generative strategies , that in all probability would n’t make it more than a few propagation .
Futurama

Kif is an Amphibiosan , a extremity of a species that ’s related to a sea cuke — and his species has a jolly … need method acting of reproducing . In the installment “ Kif Gets Knocked Up a snick , ” Kif want to square off down with Amy , and becomes meaning — but it ’s not exonerated who the literal female parent is . Because , as we discover , when members of Kif ’s metal money fall in love , their cutis becomes semi - permeable , and can take on DNA from anyone who touches them . Anyone . In the end — spoiler alert — we discover that Leela is the genetic parent , but Amy is the “ smizmar , ” or person whose honey made the construct potential . Kif pop off back to his homeworld to spawn , and his tadpole - like offspring are clearly in danger of being eaten by random marauder before they even reach the pool where they will live on — for twenty whole geezerhood .
lash out the Block
We loved this movie about outlander attack a British council demesne … but the aliens ’ method of reproducing does seem a bit windy . This is a species in which the males seem to greatly outweigh the number of females , and they reproduce through galaxy - sweep biologic diffusion ( call back , space is very empty ) . They arrive on Earth as flame meteors , but they ’re able-bodied to be killed by attack , impalement and blunt force trauma ( their completely aphotic pelt , covered in a furry cilium , are black as distance , without any other protective nut or casing ) . The specie is also seemingly unsighted , yet they have bioluminescent teeth , which , as seen in the motion-picture show , serves no intent but to alarm quarry . All of the males have to enlist in a complicated hunt for the lone female , via scent alone , and it ’s not clean-cut whether more than one male person can impregnate her . ( She would have to have a wad of babies , to make this all worthwhile . )

Star Wars
The sarlacc not only swallowed up Boba Fett , it ’s also created tons of surmise about the heavy sand - oral fissure ’s mating praxis . And it turns out thatsarlacc sexrequires an intense routine of coincidence . Somehow , an adult male sarlacc comes in contact with a female , where it inject sperm cell into
the female egg sac . The female person then ejects spores into tabu space where , with any hazard , they will pass an inhabited planet and impound itself to a creature of a sure size of it as a parasite . finally , the sarlacc detaches , and fends for itself as a predatory worm , challenging gravid and larger wight as it grows . If it is not killed and eaten , the sarlacc will eventually encounter a animal large enough to eat it , where it again experience as a sponge ( alter accounts say it will kill its host in a flash , so the creature must be very large to avoid decompose immediately ) until it grows large enough to eat its host from within — at this point , it will grow its beak - like”tongue ” and tentacles . When complete , the sarlacc is ready to dig its burrow and grow root , where it develops a secondary , gird mouth , and becomes a pit .

Doctor of the Church Who
Similarly , in “ The Twin Dilemma , ” the alien caterpillar Mestor planned to detonate a major planet , in hopes the shock absorber wave would carry its nut across the galaxy . What is it with aliens sending their eggs into space ? Remember : quad is very , very empty .
Animorphs

In this account book serial , itappearsthat Yeerk reproduction ask the spinal fusion of three case-by-case Yeerks into a exclusive organism - – a outgrowth none of the “ parents ” survive . The adult Yeerk eventually break aside into C of offspring “ grubs ” – - Yeerks have no living parent , so the grub , who who are parasite but also need “ Kandrona Rays ” to survive , are left to fend for themselves .
K - kiss of peace
Apparently there ’s more to this species than just Kevin Spacey asterisk into space in weird dark glasses . The K - Paxians , or “ dremers , ” as the ledger version ring them , have a method of reproducing that the book delineate as “ super unpleasant ” , involve intense pain in the ass and ugly odors . As K - Pax explains , “ It ’s more like having your gonads catch in a bench vise , except that we feel it all over . You see , on K - PAX painfulness is more general , and to make thing worse it is assort with something like your sickness , accompanied by a unfit smell . The moment of culmination is like being kicked in the stomach and falling into a pool of MOT test jack . ”

Star Trek
According to someof the Bible , the Andorians have four genders : Zhen , Shen , Chan and Thaan - – and each is needed to form a telepathic adhesion in order of magnitude to reproduce . The complicatedness of this quadrigender image has really caused the metal money to be drive to near extinction .
Alien

The Xenomorphs in the Alien picture have a weird method of reproduction , if you think about it — first of all , they need to plant egg in spite of appearance of a master of ceremonies , like some wasp species , but compatible hosts are probably a lot heavy to observe in infinite than in a terrestrial environment . And then there ’s the fact that they apparently take some DNA from the creatures they found eggs in , hence the Xenomorph dog . How different can your deoxyribonucleic acid be , before the Xenomorphs are n’t able to make use of it ?
Killer Klowns from Outer Space
The aliens seem to reproduce through spores resembling popcorn – which they also use as rifle ammunition and locomotive engine fuel .

Invasion of the Body Snatchers
The “ pods ” travel to a planet , desolate it , and then move on to the next world — which seems like a lot of work , with probably drawn-out menses between major planet . In the original novel that all the pic are based on , it ’s spelled out that the “ pod hoi polloi ” only hold out for five years , after which the world is left depopulated and they have to find oneself a raw planet to take over . ( Also , in the original ledger , the aliens are pretty promiscuous to frighten off . ) As one of the pod people explicate , “ The duplicate is n’t perfect . And ca n’t be . It ’s like the artificial compounds nuclear physicist are put on with : fluid , ineffective to hold their form . We ca n’t live , Miles . The last of us will be utter … in five twelvemonth at the most . ”
Star Trek again

And then … there ’s Pon Farr , the Vulcan sexual union ritual . It ’s true that the Vulcans populate much , much longer than humankind , so a once - every - seven - year mating process could figure out . Although the penury to have deadly combat with any romantic contender as part of the foreplay could reduce the fecundity rate quite a bit .
It has to do with biota … Vulcan biota … The birds and the bees are not Vulcans , skipper . If they were , if any beast as proudly logical as us were to have their logic ripped from them as this sentence does to us … How do Vulcans choose their match ? Have n’t you wondered ? It is not [ done logically ] . We shield it with ritual and impost shrouded in ancientness . The humans have no conception . It strips our minds from us . impart a lyssa which pull away our veneering of civilization . It is the Pon Farr , the time of mating . There are case law in nature , Captain . The gargantuan eel birds of Regulus Five : Once each eleven years they must come back to the cavern in which they think of . On your Earth , salmon … they must return to that one stream where they were born to spawn , or to perish in trying … We are driven by forces we ca n’t control , to return home and take a wife . Or die .
We moot the logistics of Pon Farr a lot in our staff meeting , and concluded that it would probably be ok , as long as you had a society where nothing bad ever happened . But it would be highly impractical for a order recovering from a catastrophe like war , pandemic … or , say , the destruction of their planet .

Also , there are the Ocampans on Star Trek : Voyager , who are only prolific once in their curt lifespan .
