Why are blue whales so enormous? - Asha de Vos

[@Silverwing14]

The narrator is a marine biologist named Asha De Vos and she was one of the people who actually researched migration patterns of Blue Whales in Sri Lanka!

In evolotionary biology the "why" question can be tough, because in that context you often ask "what made natural selection force this animal into becoming this size". I guess when eating large quantities of small organisms then size matters, higher net gain in energy, in a fashion that couldnt be competed out with smaller whales having less need to sustain themselves but also having a relative drop in energy source as well. Then you got the aspect of potential predators etc, a just-so story.

[@1503nemanja]

A question for people who study biology. Is there such a thing as a size trap in evolutionary terms? It seems evolution favours growing bigger as a defense against predators and for other reasons. But bigger animals need more food and when a disaster happens, like a great extinction event, the bigger species generally can't adapt and die out. Which means big species like the BW or T-Rex dominate the world in their era but eventually tend to die out becoming evolutionary dead ends, failures. Or am I wrong?

[@estebanchicas6340]

1503nemanja Bigger animals means bigger lifespans, smaller (rabbits, bacterias...) have smaller lifespans, so they need to reproduce more than the bigger ones, so, we have to sides of the coin, if you're bigger, you'll live more but reproduce less, evolution don't "recommend" to be bigger nor smaller, that's why bacterias keep existing and whales too, there's no dead end, if a animal can eat enough to maintain itself and reproduce, it's a success, if you can't, well.....you're pretty much dead.

[@ElSayyidCampeador]

bats can live 40 years and lions 14 years. it's not so simple.

[@estebanchicas6340]

Chiron Wode Yes, there's cases where is different, but if you see them in general, bigger=larger lifespan.

[@kevinreyes2364]

You need to remember that evolution is blind, and depends heavily on the environment. To say that those extinct species are failures is saying that they had a purpose which they didn't fulfill, which of course is not true. Remember that 99% of species that have lived on Earth are extinct by now. If there was a purpose, even though there isn't, it would be to pass the DNA to future generations, and DNA transcend organisms and species, so... Not much of a big deal if some species go extinct.

[@masashing4892]

The blue whale's mean lifespan is several times longer than humans like for several centuries.

What did the blue whale look like before they do now? What caused the whale to evolve into its current form? I found the size of the esophagus very interesting. Why would it be so small on such a big animal? It's questions like these that you can ask about every animal and plant that gives you pause while contemplating evolution.

[@jimdennis2451]

I totally agree! And how are the heck are you not a native English speaker? Frankly, you type better English than most people on the Internet :D

[@VosTalidos]

They are not. Whales, as well as dolphins, are mammals like us. They are warm blooded, give birth to live young, have hair (not a lot, but it's there), and breath air. Fish are cold blooded, (generally) lay eggs, have scales, and breath water through gills. A good tell is to look at how their tail fin moves. Fish, like sharks, move their tails back and forth horizontally to swim, while whales and dolphins move their tails up and down vertically.

[@atalentlessidiot7872]

I actually read the title as "Why Are Blue Whales So Emotional?"

[@FewVidsJustComments]

how?

[@MsCocohaha]

Because Krill feed on phytoplankton, little microscopic organisms that flourish in upwellings of deep waters at the Antarctic convergence. These upwellings are full of nitrate and phosphate that act as a fertilizer for the phytoplankton. When you combine that plus the 24 hour light they receive in the Antarctic, it allow them to flourish. Krill are large enough to be eaten by large animals, so animals get a large amount of energy from the kill because it's close to a primary food source.

[@mikeinside]

Perhaps watch the video again? It explains how the blue whale's ecological niche of krill dietary specialisation encouraged a huge body size in order to maximise the efficiency of it's caloric intake versus expenditure. If you're interested in what the ancestors of whales looked like, we have an impressive fossil record, and data from molecular phylogeny continues to give us a more detailed picture of the past. It's no good asking questions if you don't put any effort into finding the answers.

[@bromleyben2004]

When the animation creeps you out but you still have the urge to continue watching?

[@WhyAdamWhy]

"So why isn't there a spectrum of sizes?" is what he is asking. You have to explain why the smaller ones were less likely to reproduce. The videos suggests that whale size is the most efficient for how they eat so smaller ones would be less likely to meet energy requirements. Also, smaller ones might have been preyed on more. Population change through evolution doesn't just happen because it can. It happens because the change makes the individuals more likely to reproduce so their genetics sp
