This Sturgeon-Paddlefish Hybrid Shouldn't Exist | SciShow News

Chromosome shenanigans have resulted in some unexpected hybrid fishes. Also, this record-breaking mouse lives at a ridiculous altitude.

It’s a mix of America and Russia. Good luck fighting it

Let the struddlefish be the solution to caviar shortages and sturgeon endangerment

Plot twist, the mice live off the dead hikers' bodies.

The presence of sturgeon-paddlefish hybrid could suggest that paddlefish should be moved into the sturgeon family. From what I learned during my biology degree, hybridization is firm evidence of animals belonging to the same biological family.

These sturgeon-paddle fish hybrids are truly odd. Even closely related species often cannot crossbreed. For example, cattle have been known to mate with other bovines (subfamily of Bovidae) and can produce viable fertile to semi-fertile offspring with Bison, Gaur and Yaks. Cattle will also sometimes mate with Eland Antelopes, Cape Buffalo and Water Buffalo, but fail to produce offspring with these related species due to karyotype differences.

Finally all that inter-species mating in Star Trek makes sense.

There was a guy at school that was caught trying to hybridize with a goat. In the honour of his attempt, he started being called, "Billy, " though his real, name was Steven. I guess he was upset that his experiment did not yield human/goat hybrid eggs. He was so upset that he quit school shortly after being discovered trying to hybridize with a goat. I wish Steven, "Billy, " luck accomplishing his goal. Keep trying, "Billy, " someday you may be witnessing the hatching of the first human/goat eggs.

2 fish with very different looks, mashed together? i am truly impressed.

I like how some of the smallest mammals can live at really high altitudes above sea level, whereas the biggest mammals often live well below sea level

[TK]

The fact small mammals can live at such high altitudes may help explain how they survived the asteroid impact that kill the dinosaurs. Because if you think about it, the problems living at super high altitudes would be a lot like surviving the nuclear winters and other effects of the impact.

Anyone else find the sturddlefish's little snouts kind of cute?

Thank you for hosting Stefan! You did a great job :)

I've had the opportunity to be a part of research efforts involving Paddlefish. They are fascinating fish.

- ”We need to crossbreed sturgeon and paddlefish.” -”Why?” -”...”

[mutantmaster]

Humans: acording to these rules, these animals can't hybridize at all
Nature: I DGAF, go for it

[deathsyth]

Nature: You can't just mash up two different animals and create a new species!

Science: I just did! Somehow...

My god, YouTube should've recommended this channel to me way earlier. I need the stuff.

It's like that old song, "Sturgeon and Paddlefish DNA just don't splice"
