"they also have more small blood vessels around their cells"... Blood vessels around their cells... Are there cells in the blood vessels around their cells that are in blood vessels?
When talking about Emperor penguins, one of the photos its actually of KING penguins. you can see the brown juveniles. probably the pic was taken at South Georgia.
Awww... I was hoping to hear why Reindeer are also called Caribou :( Because I looked it up and apparently they're of the same genus but two different species.
Turns out Nature resists simplicity. we like to put everything in neat buckets, but nature isn't neat. Caribou look a lot different than Reindeer, and they come from 2 different places separated by a lot of space, so they're 2 different species by one definition. but, it turns out they can interbreed and produce fertile offspring, and that means they're the same species by another definition. Interestingly it may be that Polar Bears and Grizzly Bears are the same species by the interbreeding definition too. if the 2 breed, they produce fertile offspring (and it's slightly terrifying). we called them 2 different species when we found them, because of the habitat separation and the physical differences. but as the polar ice melts and forces the polar bears south, the environment of the grizzly and the polar bear are starting to overlap, and they may be interbreeding in the wild now. if their offspring are fertile, they're the same species. Polar Grizzly! :D
The bar headed geese migrating that high is sort of a myth particularly the idea that they do it regularly. Studies have shown that in general they uses mountain passes where available (Wikipedia sourced). They have still been found flying that high, with an enverified report of them topping Mount Everest, but that isn't a routine part of their migration. The coolest thing I found about their migration is that they have the highest rate of climb of any migrating bird and that they climb when the tail wind is lowest and therefore do so with the least assistance from the wind!
(4:06) 4, Bar-Headed Geese: I've heard the same thing about cranes, probably in a Sir David Attenborough show. Sudden storms can really make things difficult. What, nothing about the distance humpback whales migrate while trying to avoid orcas... or the monarch butterfly, how they manage to find their migratory mountains in Mexico?
The most perplexing to me is the migration of eels from the UK to the Sargasso Sea. I researched it for my degree and calculated that since the eels don't feed in the salt water they shouldn't be able to store enough energy in their bodies to make the journey
So, you expect a caribou to have enough ass gas to break through the atmosphere? You seem like an entitled book boy mechanic. A little biological understanding never hurt amyone.
An honest question: isn’t it a stretch to call migration a travel that cycles on a daily basis? When people go to work every day, from residential areas to the center of the cities, is it also a migration? Or would all people in a certain area need to do it for it to be called a migration?
When the famed Japanese animator was asked to choose his favorite character from among his many creations, he immediately named "Stingrid", the multi-tentacled main character first introduced in his most popular work, "The Clown-fish's Landlord." Asked why, he explained, "Anenome of my anime is my friend." (Sorry ...couldn't help myself.)
@@bjornolson6527 after resorting to a degree of contrivance that tests the limits of even the most forgiving reader, only to pay it off with a mere pun - generally regarded as the lowest form of humor - I am quite grateful for your comment as I am willing to disappoint the crowd so long as I manage to amuse AT LEAST one person (other than MYSELF!). So thanks for that!
@Tim Sullivan This was far from the typical droll pun, albeit (artfully?) contrived. At the risk of conflating puns with such “high-brow” humor contained in Comic Relief’s “Doctor Who and the Curse of the Fatal Death”, I take humor when I find it. Lif, Laf, Luf.
@@bjornolson6527 - just finished watching that Comic Relief spoof (which I admittedly had trouble distinguishing from what memories I retain of the actual show - although these recollections are far from reliable as my exposure to "Dr. Who" was both limited and long ago. ... Anyway got to get back to work on my compilation of Trump-themed limericks, so thanks again and take care.
aren't the golden jellyfish freshwater as well? or is that a different species of jellyfish that got stuck in a lake on a pacific island due to receding water levels during the ice age? doesn't one species of crane that lives in Hokkaido part of the year also migrate over the Himalayas?
As a New Zealander, I point out that those terns are just plain dawdlers; Bar-tailed Godwits do 11,680 km from Alaska to New Zealand non-stop in eight or nine days, without food, water or sleep!
Hannibal Lecter: "Terns? If I help you, Clarice, it will be 'turns' for us too. Quid pro quo - I tell you things, you tell me things. Not about this case, though. About yourself. Quid pro quo. Yes or no? [pause] Yes or no, Clarice? Poor little Catherine is waiting."
@6:00 that's a King Penguin colony, not Emperor penguins. Emperors don't have colonies *anywhere* that's warm enough to have abundant grass, not even in high summer. Also you can see the chicks, which are solid brown, not the gray, black, and white of Emperor chicks.
...I think the bar-headed geese actually fly at 7,000m above *sea level*, not above the ground. If they flew at 7,000m above ground level while going over the Himalayas all the evolutionary adaptations in the world wouldn't be enough to let them breathe. :P
You missed out my favourite migratory species. The American blue grouse migrates every year from the mountainous pine forests in their winter home, to their summer habitat of the deciduous Woodlands... 300m away...
At 4:30 I guess it meant to say the bar-headed geese fly over 7200m above sea level? Flying an additional 7000m above ground over the heights of Himalaya would put them into the lower stratosphere.
Will all animals live in peace and harmony with each other once we invent artificial meat? Will wolves befriend sheeps now when evolution benifits cooperation instead of competition? Will all animals start to speak the same language and communicate with each other to benifit each other survival?
My favorite 5 animal migrations: Arctic Tern, Monarch Butterfly, Serengeti Wildebeast, Bar-Headed Goose, and Humpback Whale. And the most impressive human migration is the seasonal migration from the US North East to Florida in the autumn and back again in the spring.
Before humans settled down, did we migrate seasonally? I know we migrated by spreading out following food, but did we move back and forth to places with seasons?
@@SuviTuuliAllan Are you talking about people who move city to city or actual like wandering tribes. (I meant pre-civilization in my question by the way)
Man i envy those penguins. I survived cancer twice and lost half my face to amputation.. a tumor destroyed my jaw and my life. I was labeled a freak. Ugly. I decided to start over, move to South America and start a youtube channel to inspire others who feel like they're not good enough for this world.. my scars will not define me. go check me out and subscribe if you want to help me grow. i want to give people a spark of change and join me on my journey!
This might sound like a dum idea. Anyhow I've seen some steampunk facial masks and maybe getting a style where having half a mask didn't look that outlandish, could work
I remember H.P. Lovecraft tried making giant blind albino penguins scary in a couple Cthulhu mythos stories. It didn't work for me... didn't induce any sort of dread or horror with them around.
I've had questions that I have even asked in the comment sections of Scishow videos before about birds and altitude that were answered in the section of this video about bar-headed geese. Thank you!
@@SuviTuuliAllan and we should remember that every adaptation has downsides. If I'm not mistaken, at least one of those adaptations (it happened several times and in slightly different ways) makes people more likely to suffer from strokes
@@SuviTuuliAllan I don't get why you are so aggressive. I was just saying that genetics does not work like superpowers, and my answer was also directed to the first comment. We might need it in some environments, but it could be a problem in some others
@@beniaminorocchi I didn't say it did. Not sure how you're reading aggression into my comment but I suppose it's why I have no friends. Why did you mention me in your comment if you were replying to the top comment?
Honestly surprised monarch butterflies weren't on this list. The distance they travel is one thing, but the fact that the butterflies who finish the journey are the grandchildren of the ones who started is really fascinating.
