Top 10 Most Shocking Cases of Interspecies SEX


Black Fly Presents 10 Horrifying Cases Of
Interspecies Sex Number One: When the female difference between
two species is pockets for the male to put his penis spines in, it’s not hard to see
where things could get confused. Ordinarily, when two Drosophila yakuba mate, the spines
on the male’s penis slot into two specifically designed pockets in the female. These closely
related fruit flies – Drosophila yakuba and Drosophila santomea – sometimes hook up, but
because there’s nowhere for the spines to go, the female gets stabbed. Number Two: When there are only females of
the species, what’s an Amazon molly to do? The solution… Cloning. The fish give birth
to live clones. Although no sperm is needed for fertilisation, it is required to produce
the eggs, so the Molly borrows men from other related species to mate with. Found in Texas
and Mexico, this fish takes its name from the Greek mythological Amazons – there were
no men in this species either. Number Three: Although related in species,
the mating techniques of the Caenorhabditis nigoni and briggsae couldn’t be more different.
The nigoni ladies use a number of males. This results in determined sperm who have to overcome
the competition. The self-sufficient briggsae, on the other hand, are hermaphrodites. In
2014, scientists experimented with cross-species relations and the results were nasty. Female
nigoni have learnt to cope with the enthusiastic sperm, but the briggsae, having never been
exposed to it, couldn’t cope. The sperm got out of the uterus and ended up locking on
where they shouldn’t resulting in diminished fertility and life span. Number Four: The Plains spadefoot toad, which
lives in the southwestern US, has to be quick about turning from tadpole to toad. The small
puddles they swim in can dry up without warning and the lung-less tadpoles can’t survive out
of water. But, nature always has a solution. The Plains toad mates with the Mexican spadefoot
toad in order to borrow the Mexican’s quick development DNA, thus creating a hybrid that’s
more likely to survive a dry spell. Number Five: Who wouldn’t fancy a bit of traumatic
insemination? Cleverly designed by nature not to be deadly, being stabbed in the stomach
with a needle-like penis is all part of the act for female bedbugs. Number Six: Get this for a family tree! If
you’re a lady ant, you’re one of two kinds – a worker or a queen. Only the queens get
to have babies, and they have loads of them. The reproductive process in ants is called
haplodiploidy and basically, the boys are different to the girls. Lady ants have a mum
and a dad, but the men only have a mum as they hatch from unfertilised eggs. This means
that male ants only have daughters which makes it super important for some of those young
ladies to become queens, otherwise there’ll be no grand kids for him and his line will
die out. Number Seven: North of Antarctica, Antarctic
fur seals are doing it with king penguins… Really? Apparently yes. Forced copulation
is the animal equivalent of rape and it’s been studied by scientists on Marion Island.
So violent that the wound left by the seal meant the penguin had to defend itself against
predatory birds who smelt the blood, the female king penguins are held down throughout the
episode whilst the male seals do their thing. Number Eight: When sea otters copulate, it’s
so rough that the female doesn’t always make it. As if this isn’t bad enough, male sea
otters don’t always stick to others of their kind. Scientists in Monterey Bay, California
have studied the forced copulation of young harbor seals by sea otters, often so violent
that injuries caused by teeth and penis were seen. Number Nine: The Montana cutthroat trout’s
addiction to sex with rainbow trout has put them in danger of extinction. Extinction by
hybridisation happens when two species prefer each other over one of their own. When most
reproduction occurs inter-species then all the babies are hybrids and eventually the
species will cease to exist. Number Ten: Here’s where sleeping with the
right one is rather quite important. Because the reproductive parts of female Carabus beetles
are designed specifically to accommodate the unusually shaped penis of their counterparts,
inter-species sex can have fatal consequences for the females. Cohabiting on Honshu, Japan,
the Carabus maiyasanus and iwawakianus better pay attention to who they’re mating. Thank You For watching Yet Another Amazing
