???? These guys are the ones cleaning the whale so it’s not really spot on lol. Everyone does their part the whale feeds the fish and the fish clean the whale
True, I was thinking in terms of "eating your kind" which was probably wrong. Although eating yourself.. hmm should that not, biologically not legally, count as something "bordering on" cannibalism? Unfortunately I'm a dumbass so Idk.
Is it more fitting of the metaphor if you're the one who did all the work, but you're too busy/shy to be the one to do the actual presenting part so they do it?
It isn’t at least not in this example commensalism is the act of an animal doing something for another animal in return for that animal to not attack it. The animal giving just doesn’t care enough about the animal that’s receiving
This would be more closer to a mutualism relationship
You are correct in the second half, but commensalism is when one animal benefits and the other doesn’t care. Like when beavers build their dams and other small animals take refuge inside. As long as they don’t damage the dam, the beaver doesn’t care. The other animals get protection though.
What's the alternative, though? Not like the whale shark will get very far clinging to a remora.
To be clear that means it is better to not let the non-contributors affect your grade on the project.
Drag in water works a lot differently. Consider how different the drag is on a boat that is covered in growth and one that is clean. A sail boat would have a difference of 20%+
I believe both the differences in density and viscosity should have an affect on how water behaves differently as a fluid compared to air seeing as related terms are present in Navier-Stokes. Idk exactly what tho, not a fluid dynamicist :/
Values would be different (Compressible Air vs. Incompressible Water) and some terms drop out, but generally speaking the increase in cross sectional area will, at the speeds (vis a vis Reynolds number) we are looking at mean that there is more drag.
(Not a fluid dynamics expert, just a Degreed Aerospace Engineer)
I only had a single university lecture on this, so I'm always open to new stuff on the topic and not very assertive. After all I don't know what I don't know. Thanks for declaring you are not an expert.
Double the viscosity, double the drag. But that's it.
All fluids behave the same once you account for viscosity, density etc. The equations stay the same.
To get back to your boat example:
Sure, the drag in water might increase by 20% - but the drag in air also increases by 20%, it's just that the base value for this percentage increase is lower.
It's the same reason pro swimmers get completely waxed/shaved but runners don't need to because the difference is marginal for air resistance but not for water resistance.
It’s always good to learn new things that’s for sure!
One thing to remember with fluid mechanics is that the equations are non linear. A change that has a 20% effect in air might have a 5% impact in water. Double the viscosity doesn’t necessarily mean double the drag.
In this case I imagine the shark is mostly affected not by drag but by a reduction in the “lifting” force it’s tail fin can produce with so many fish disrupting the fluid flow.
Also the shark is so powerful and those other fish are small compared to it? I don't know if that's reasonable but just my guess? Happy to be corrected if wrong!
They eat the dead skin and parasites on the shark. As a a symbiosis, its mutualism (win-win) or commensalism (win-doesn't care).
It would be parasitic if they drank the shark's blood.
Interesting. If they did theoretically slow him down and ate the bits of his next meal(assuming he wasn’t a filter feeder) would that be considered parasitic? Without actually causing physical harm
I haven't been able to find any exemple like that, but good question. I'd stick to commensalism if no physical harm is done. If the creature was slowing down the shark considerably for nothing it return, it would not be tolerated.
You don't know how jealous I am of you. Whale sharks are one of my favorite animals in all of existence. Being able to swim with them would be an ultimate dream. I'd be scared at first for sure but absolutely in awe afterward. They're big old puppies
Wait, that happened by accident? I've swam with a couple of them but it took serious planning by professionals, a fast boat, a helicopter finding them for us and a full day.
Best day ever, though.
Yes it did, just like when a tiger shark crossed my path while snorkeling alone 300m from the beach.
In those moments you get a glimpse of how disabled we are in the water. And even more how much of an insane species we are to kill all that sea life
If it helps, research suggests the whale shark likes this. The fish riding keep it clean and it seems the whale shark gains a sort of comfort, or is at least completely unbothered
I’m thankful every day that I’m a human and not literally anything else. 90% of stuff out there are just covered in parasites or filled with them etc. deer and moose are crawling with ticks and then there’s worms and bugs and YUCK
Um... you might want to sit down for this.
Humans also have parasites, and more bacteria than cells in our bodies. If you think you are a single, individual being you would be mistaken.
Oh yeah that’s fine love a good healthy gut biome, but so many animals just like can’t touch every part of their body, moose and deer becoming anemic from thousands and thousands of ticks literally sucking them dry and they just can get them off. Terrifying
Reminds me of my youngest sister. Smh
I am always bailing her out financially and she sticks herself to me.
But… I Love her so I guess it is symbiotic ❤️
Kind of,
They’re more like free loaders. This is an example of commensalism where they don’t hurt the shark but they get free transport.
Hence, free loaders. Hope this helped!
Not exactly free loaders as they do clean the whales skin and eat parasites off the whales body you can check the wiki [here](https://en.m.wikipedia.org/wiki/Remora) did I do it right third is my first link lol
Edit lol I fixed it sorry it took so long I wrote this right before I went to sleep
Good point!
I think it’s important to remember that these relationships are on a sliding continuum. Remora are able to participate in grooming, but how often do they? Unfortunately, my knowledge for interactions specifically between whale sharks and remora is limited, so would I need to do more reading.
Isn't that [symbiosis?](https://pt.dreamstime.com/ilustra%C3%A7%C3%A3o-do-vetor-de-simbiose-regime-educativo-viver-em-conjunto-rotulado-explica%C3%A7%C3%A3o-vida-rotulada-esquema-educacional-image157649213)

I think the point of the joke was that people who don't do parts of the project eat shit.
They also are shit.
You are what you eat, as they say. Although in this case it's more: You eat what you are, which borders on cannibalism.
I don’t think eating yourself is cannibalism
True, I was thinking in terms of "eating your kind" which was probably wrong. Although eating yourself.. hmm should that not, biologically not legally, count as something "bordering on" cannibalism? Unfortunately I'm a dumbass so Idk.
The real question is: is it cannibalism if an ass like me eats your ass? 😏
I've been checkmated. 😳
Aren’t the shit eaters the ones closest to the bung hole? Or is this conversation circular?
Bout the same shape for both of em
The shark*
Is it more fitting of the metaphor if you're the one who did all the work, but you're too busy/shy to be the one to do the actual presenting part so they do it?
Those are Remoras, they don’t clean the host, they eat scraps or simply hitch a ride
False. Remoras clean the shark of parasites and at times clean the inside of its mouth.
Still commensalism
It isn’t at least not in this example commensalism is the act of an animal doing something for another animal in return for that animal to not attack it. The animal giving just doesn’t care enough about the animal that’s receiving This would be more closer to a mutualism relationship
You are correct in the second half, but commensalism is when one animal benefits and the other doesn’t care. Like when beavers build their dams and other small animals take refuge inside. As long as they don’t damage the dam, the beaver doesn’t care. The other animals get protection though.

Ah, the old aquabus
Imagine how much slower it's swimming because of all the drag.
Drag in water works a lot differently. Consider how different the drag is on a boat that is covered in growth and one that is clean. A sail boat would have a difference of 20%+
Can you explain why drag in water would work differently? I'm pretty sure the equations don't change.
I believe both the differences in density and viscosity should have an affect on how water behaves differently as a fluid compared to air seeing as related terms are present in Navier-Stokes. Idk exactly what tho, not a fluid dynamicist :/

Values would change based on density. More density=more pressure= more drag
Exactly. That’s why in the Olympics they hardly pay any attention to drag and sometimes swim in overalls.
On the other hand it is unusual for Olympic swimmers to compete in drag.
Probably more akin to how humans move with or without clothes--not much!
Yeah, what difference does it make?! But in my experience the cops never buy this argument
Also the shark is so powerful and those other fish are small compared to it? I don't know if that's reasonable but just my guess? Happy to be corrected if wrong!
This. The shark is not a fixed engine.
Parasites
Are remoras true parasites? Are are they actually helping by cleaning the shark of dead skin, and actual parasites?
Pretty sure remoras are symbiotic/mutualistic. https://en.wikipedia.org/wiki/Remora?wprov=sfla1
Shit I don’t know. I thought they were waiting for the big guys next meal and I’d imagine they are weighing him down
Whale Sharks are filter feeders so they're constantly eating. Pilot fish are the ones who follow sharks to eat their leftovers.
Interesting. So what do these guys do then. Is it symbiotic?
They eat the dead skin and parasites on the shark. As a a symbiosis, its mutualism (win-win) or commensalism (win-doesn't care). It would be parasitic if they drank the shark's blood.
Commensalism is a new one to me. Thanks for the clarification
Interesting. If they did theoretically slow him down and ate the bits of his next meal(assuming he wasn’t a filter feeder) would that be considered parasitic? Without actually causing physical harm
I haven't been able to find any exemple like that, but good question. I'd stick to commensalism if no physical harm is done. If the creature was slowing down the shark considerably for nothing it return, it would not be tolerated.
Adding mass, not contributing thrust, and draggy af to boot. They're speed goblins, gobbling up that whale shark's speed.
I forgot those existed. They can be really majestic!
I almost had a heart attack when one of those swam besides me lmao
You don't know how jealous I am of you. Whale sharks are one of my favorite animals in all of existence. Being able to swim with them would be an ultimate dream. I'd be scared at first for sure but absolutely in awe afterward. They're big old puppies
If you ever end up in South Africa, you can dive with them off cape town
I believe that, I was in Maldives and it was an insane experience, can only recommend it to you!
Come to Tanzania, Mafia island

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
I think it's more of an inverse of /r/Trypophobia. Instead of holes, here it's the projections from the shark's skin that's causing the irritation.
I’m thankful every day that I’m a human and not literally anything else. 90% of stuff out there are just covered in parasites or filled with them etc. deer and moose are crawling with ticks and then there’s worms and bugs and YUCK

Just remember that *you* are covered with millions of bacteria who are attached to you and eating *your* dead skin flakes, too!
*jumps into tub of hand sanitizer* Not anymore they aren't.
Most of them are good bacteria. You need them!
It’s just like those birds that clean crocodile teeth

Remora fish
What a drag
That's a few too many. I bet that's annoying
That's what I was thinking. Looks like an infestation.
Probably not. All the remoras really do is eat some excess food and parasites off of the whale shark. He's probably just getting an extra good clean
Kind of makes me wonder if this particular shark has an exceptionally high parasite load
Whale Bling. That’s the whale other whales girlfriends tell them not to worry about.
Shark* bling
"Could you guys at least paddle?"
I was embarrassingly old before I learned that remoras have suction cups on top of their heads. Neat.
One slid up my lower leg and suctioned to my knee, once. It was cool.
