Science: "Why these fishies don't breed?" Fishes: "We immortal bro. We don't need no bebbies!"
-
When I think long-lived, I hope and think of Hank Green.
-
When you think "long-lived", you think of tortoises, redwood trees and David Attenborough... that got me! 🤣🤣🤣
-
I wonder how the conditions of the lake have changed in the last 40 years since, presumably, the last time they did spawn?
-
As someone who's done otolith readings, I can only imagine how tedious it has to be for a fish of that age.
-
I wonder if the fish seemingly not reproducing is part of the reason they live so long. Maybe their biology is like " yo there are no kids around need to stick around until that changes". Reminds me of how some octopi have kids and are just like peace out and promptly die.
-
I wonder if they aren't breeding because they aren't getting the cold spell of winter like the Great Lakes region gets. A lot of our fish rely on that to spawn come spring when the water warms up.
-
Man it is weird having a SciShow video about something so close to home, as a kid I went fishing at Apache lake at least once a year. Never caught anything besides trout, but it is neat to see it played a big part in research of those fish
-
it brings me so much joy seeing how good Hank looks
-
It may not be as sexy as discovering a comet but it is still valuable work. It's great when plain, old citizens can help out with real scientific research.
-
The worst part about the overfishing in their native range is that it’s often bow fishermen killing what they think are invasive carp so they DONT EVEN EAT THEM
-
It's always thrilling to see a video about a location you're familiar with! Lake Roosevelt has Buffalo fish... And also a pair of glasses I lost there.
-
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.
-
There's a story about deep sea fish (orange roughy) that were picked out as prey by fishery after having depleted all their other catch. The population was destroyed within years, and only then did they find out that the fish were extremely long lived, so were extremely slow to replenish their population. They were up to 148 years old, took 32 years to mature)
-
That 2:20 quote about older specimens having better immune function and lower stress levels than youngsters really hit me where I live.
-
“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).
-
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...
-
Thanks so much for this video. That first picture you showed when introducing the Buffalofish, is actually a common carp on top (and a Buffalofish on bottom). You can see the barbells on the sides of the common cap’s mouth. I’m not sure about the fish at 3 o’clock. Just thought you would be interested to know. Loved the video!
-
I've lived in Phoenix since 1976. I've visited those lakes many times. But, WOAH! I've never known about those fish. Thanks Hank.
