“Or floating at the top of your home aquarium… ya know, if you’re bad at fishkeeping.” Bold words from the man who inspired my fishkeeping hobby (along with James and the microcosmos crew).

When I was 6 or 7 I caught a buffalo carp that was almost 4 feet long, which was almost as tall as i was! It was one of the first times i went fishing, so that totally ruined fishing for me for life, every other time catching small fish was so boring compared to the fight and struggle that thing gave me.

As a citizen scientist, this message makes me feel so validated 😁

The *Greenland shark* _(Somniosus microcephalus)_ is estimated to live to an astonishing 250-500 years, making it the longest lived vertebrate organism. It achieves this by living in slow-motion, with an extremely sluggish metabolic rate (it gestates its young for a stunning est. 8-18 years). Its eyes sadly tend to be prone to infection by a rather nasty crustacean parasite - often rendering it blind...

Love the channel. Love the stories. This one was has of my favourite scientific ’WTF’ moments. Thanks for sharing!

So many mysteries here! Great video!

I caught a Buffalo Carp on the Mississippi river about 40 years ago and it was about 3' long. I wonder how old it was since the fish in this video didn't look as big.

Fisher people are often very good citizen scientists! One time when I was little my dad caught a fish with a tag that told him to contact the fish and wildlife service to tell them where he caught it and he did and this sort of thing teaches scientists a lot about fish migration. Now I'm an adult and in college studying ecology and I had an internship looking at culverts to see how much of a barrier to fish migration. (Every day when we were in the water, locals would come over and ask us if we caught anything lol😂) Fisher people tend to really know their stuff so scientists can ask them a lot of questions about the behavior of fish. I think this is probably true for hunters, but there are fewer of them in most areas because there are higher barriers to entry for hunting. I'm looking for jobs in conservation and there are a lot of organizations which were founded by hunters. Ducks unlimited is an example which is an organization that protects wetlands and it was founded by hunters who noticed fewer and fewer game birds as wetlands were being destroyed. I know a lot of people in my major are vegetarian and don't like hunters or fishers but they tend to be very good conservationists because they have such an intimate relationship with the game and thus with wildlife.

Yooooo AZ represent!! I love watching things and getting places referenced that I have actually been to many times

Excellent presentation

David Attenborough indeed.

Very interesting, caught a 10 pound one of these at a marina once. It had a thick slime coat that had a horrible odor. It also taught me its one of the only carp species in the U.S that targets live fish species because I was using a spinner lure mimicking a injured baitfish. At the time I didn't know Buffalo Carp were opportunistic feeders and can eat live fish. I wonder how old that fish was looking back at it.

Great content love the Theodore Roosevelt opening.

My uncle is a fishery officer & he mentions that carp dont spawn with each other of the same water body. They will spawn with other carps from other water body. Like two ponds for example.

Wow! This is such an interesting case and maybe delving more into this may help humans live longer! ❤

These fish: Less stressed as they age. They're moisturized, relaxed, staying in their lane and living their best lives.

Hi Scishow, been watching you for like a decade, love the show. I live in central Minnesota, where big mouth Buffalo are native, and they are not endangered or overfished. I honestly haven’t ever met an angler that goes after them, I’ve heard of them, but there’s not many. I think a lot of people don’t even know they exist because they aren’t a popular game species like walleye, pike, bass, and panfish.

I grew up fishing the Great Lakes and know of no one that would keep a buffalo fish.

greenland sharks: "I'm about to end this fish's whole career"

The arch/suspension bridge behind Roosevelt dam, is one of the most amazing sights I've ever come across. To get there, I driven on the dirt track up from Apache Junction for a couple hours, with broad stretching desert canyons , washes and hills in every direction, and hardly a speck of anything man-made in view... When around the corner comes a large, imposing wall of concrete holding back Roosevelt lake. Its far from the biggest, or most impressive, and in fact it's not but a footnote in the story... At the top: originally built as an alternative to driving over the dam itself, because it had been built too short to hold back the possible waters of a 100yr storm... This small arch/suspension bridge frames perfectly the mountains in the distance on the other side of the lake. The placement, style and artistry of it, ADDS to the beauty of the vista, in a way that I have not seen many times. The bridge isn't the focus of interest, nor is the glassy lake behind it or the mountains in the distance. They together create a picture that will live in my mind for the rest of my life.

It’s a food reserve for the underground secret base.

According to Wikipedia it wasn’t until 1959 that the dam was named after Roosevelt (about 40 years after he died) so he didn’t name it after himself.

We brought it to the lab and extracted the ortholite, and it turned out to be 28-29yo. It was also sterile, which all many of the longest pikes also are. Colleagues of mine dissected a 141cm long northern pike, which was found dead floating around (and would have been a lenght swedish record, where it caught alive). That fish was 30+ years old (anyone cutting ortholites in half know there's some discrepancy in those numbers). 1. Those are some dang old fish. 2. Cudos to whoever spent hours on end, cutting those in half and counting the marks on it.

Wether old fish just retract/devolve their gonads once they are ready for the retirement home, or they grow that big because they dont have to waste energy producing eggs every year -is still not clear. But it sure is interesting (well, at least for anglers, fish biologists and limnologists). But it has been noticed in many "oversized for their species" fish.

Re. not breeding - in the UK there are tens of thousands of carp, that grow to 50+lb and live for decades, but hardly ever breed successfully - apparently something to do with summer water temperatures not being warm enough for the fry to survive. So just because adult fish of a species can thrive in an environment doesn't imply that they can breed successfully.
