The way aphids and clams have so strongly incorporated their bacteria reminds me of Mitochondria, and how they were once their own organisms, but joined forces with animal cells, merging so that they essentially became one separated yet entirely dependent system.
Blue Ring Octopus isn't overkill, it's Australian! Its a proportional response to the surrounding hostile fauna :P A tourist picked one up last week in their hand and filmed it with their smartphone cause it was cute, they got really lucky not to get poisoned... locals just know to avoid it, as direct contact is the only way to get poisoned. Its also one of the few venomous creatures in Australia, we don't have anti-venom for. If you get medical attention in time they can keep you alive, but your paralysed and may suffer severe nerve damage. One person went blind cause he couldn't close his eyes, but only 3 deaths in the last century.
@@owenpaus4836 Good luck with that Australia literally have spider string going through the sky as normal weather there. (Usually a a bunch of unseeable tiny spiders are on one end to get away from home, and riding the wind.)
And theres always those few couple that have genuine good relationship that makes you wana take a knife and killed one of them so they be separated forever and if ghost exist they likely seeing their partner moved on and spy them forever and get NTR.... Just me? Ok glad i dont have friend
I mean if a blue ring octopus could choose between an intelligent brain and secure and long lasting life or poison, color changing intelligent brain and short lifespan....yeah i would be a blue ring octopus too Jk
You speak really, REALLY fast. On one hand- I'm truly impressed. On the other hand- I often find myself getting "left behind" bc I don't have time for a moment of thought on new-to-me information.
8:45 soo cute I wish I could pick it up I love how the rest of the animals use bacteria for ingestion, and poison and this one is just like: *galaxy leggings*
Quick correction: Hawaiian bobtail squids are much larger than 3 centimeters. I would know, I actually did lab research into how the Hawaiian bobtail squids symbioses with V. fischeri and the winnowing process that the squid uses to ensure only V. fischeri colonizes its light organ. We had a couple mating pairs and they were closer to 7-8 cm.
an interesting question regarding the bacteria that have been living forever in the aphids and the clams: at what point are they no longer separate species and instead internal organs, sort of like the mitochondria in humans?
This symbiotic relationship between aphids and Buchnera is pretty impressive, but it doesn't change the fact that aphids usually serve as snacks for ladybugs and ants.
Glad he clarified that these are mutualistic symbiosis. Parasitism is a type of symbiosis. The point is that symbiosis is not always as great as it sounds.
I have to write a rough draft for a mock research proposal for a Symbiosis class by Thursday and I've been really struggling picking something that hasn't already been extensively researched. I think I'm going to go with the blue-ringed octopus, given it's controversy. THANK YOU! I love you Hank and Sci-Show. Best Valentines gift ever.
Man, I wish humans were able to produce tetrodotoxin! Or...maybe something that allows for us to bioluminesce! Excellent video, Hank! I had forgotten all about parthenogenesis.
thankyou for choosing this job, seriously.......... crashcoursing and funfacting are some of the few things I can still genuinely appreciate from this life.
A cool partnership that is weird are leaf cutter ant's, they don't eat the leaves they harvest, they use them to cultivate a fungus, they then eat this fungus.
Probably, assuming that the environment is suitable for the bacteria to grow and that it doesn't cause any serious harm to the human. The better question is - why would you want to eat this dry woody desert thing?
My school Green House got infested by aphids. It took months to get them out. we had to hand scrub thousands of lettuce leaves for salads at an event we were hosting. It took forever and they were all over the kitchen.
@@ToxicTerrance I went from "Wait, what? That's today??" to "okay I guess I don't pay enough attention, I must have been mistaken" to "oh nevermind other comments are mentioning this too"
The area in your brain which remembers how calendars work is the same place that information about bacteria symbiosis is stored, so you can only know 1 at a time.
Gut bacteria is neat to have! Kinda like endosymbiosis, one of my favourite topics in biology! Thats how ruminants and termites digest cellulose, btw...^^
The Blue Ring Octopus is so venomous because crabs are pretty dangerous prey for a little octopus. The Octopus really needs it dead before rasping into the shell with its tongue. Aussies kids are taught not to play with random little animals because these little fellows are pretty common but hard to see unless they flash their blue rings.
Valentine's Day is the 14th of February, not the day this was posted; you could have waited a few more days so Hank wouldn't look so foolish - Hank you're being undermined from within.
I'd like to do my 3rd yr dissertation on mutualistic symbiosis. I'm especially interested in possible exchange of genetic information or proteins between host and symbiont as well as the co evolution and the loss of gene in the symbiont over time. Anyone got any ideas of cool examples?
I have to deal with aphids every year, the green ones dont give me much trouble and I can get rid of them pretty easily but now the black bean aphids love my zucchini. I have tried everything to rid of them from neem oil to whatever says it kills them at lowes or online XD I found the next best thing is just to constantly feed the plants to make up for the lost nutrients. Weirdest thing is they never go after my green beans or sweat peas LOL
Who else had a small heart attack when he said happy valentines day. Thinking Oh !@#$ I forgot about the chocolate, flowers, and the dinner. Then come to realize as you're trying to figure out how best to avoid the Apocalypse. You have four days until Valentines day remaining.
I like the relationship between humans and lactic acid bacteria. Some say it's bland and too cheesy, but in Asia you can see some kimchi stuff going on, if you want to spice up.
Aphids are the ultimate probiotic complex. Evolutionarily speaking we are the only plant consuming animal that does not consume live aphids every day. Noticed a bunch in all my ripe raspberries always wondered why my all my allergies go away every year after I start eating them. I mean all my allergies I don’t even get welts from mosquito bites.
So, because it’s Valentine’s Day it’s obvious that we are going to talk about bacteria, Lol. Nice job, you guys know how to explain science being fun and funny and staying on topic.
It's valintines day people all around the world celebrating love so that means we're going to be talking about bacteria Oh my god Hank how did you know
Despite all those sources, tell me honest: did you guys read 'I contain Multitudes' before making this one? Cause that is one amazing book in which these examples and a bunch more all appear
