I am not only awed by the size and bulk of whales, but also the sheer meatiness of shrimp. It seems like these organisms are > 90% meat. Why do they have so much meat? What do they need all that meat for?

Whales cultivated them for consumption.

A big blue whale is about 190t 16t is 8.4% of your body weight. That’s a 200lbs person eating 16lbs of food. Is that impossible? I’d love to see a breakdown of macros of humans and whales. I think 16t wouldn’t seem so crazy.

Joey Chestnut eats about that much weight in just a few minutes each year.

It's not impossible, but I'd say pretty rare to find someone who can do so.

Earlier quoted context omitted.

I have a population of shrimp that have been breeding in my aquarium for quite some time now. They spend most of their time picking through detritus and otherwise managing the cleanliness of the rocks and sandbed. I'm curious if their 'meatiness' has something to do with how rapidly they grow and reproduce and the size of the clutches involved. A single female can have around 100 eggs or more attached to the undersid…

Caton in Overshoot called humans a detritus species. Your very descriptive paragraph might be mined for metaphors. For example, in place of a brain, does humanity have going a peristaltic action connecting mines to landfills?

Your username and comment make me think GPT3 wrote this. What do you mean?

Hmm, being in the ocean means they have to burn a lot more calories relative to their mass, I imagine.

A related article has an amazing fact: in the 1800s, humans killed as much whale biomass as all mammalian biomass alive today. https://www.theatlantic.com/science/archive/2021/11/whaling-...

All wild mammal biomass. Domesticated mammal biomass is massive. In fact, humans + our livestock comprise 96% of mammal biomass: https://www.greenpeace.org/international/story/17788/how-muc...

This was a shock for me when I learned of this. It's a great way to show people who think humanity somehow doesn't have the capability to have an effect on greenhouse gas emissions for example. We have totally and completely reshaped the earth in a matter of centuries in what should normally take thousands or tens of thousands of years.
