I'm just imagining the stickleback is constantly salivating whenever he sees the eggs. And then he's like, "No! No! Can't eat the eggs! Can't eat the eggs! Can't... eat... the eggs... Damn it!"
Stopped studying for my university bio exam to take a break on TH-cam, first thing recommended to me is this video of exactly the same animals few animals I was just studying
low weights and high reps are good look into strongman exersizes and the website and youtube channel "The Art Of Manliness" im trying to do some controlled bodybuilding so i can do modeling
Oh wow that moa fact is incredible! When humans arrived on NZ they would've probably hunted the biggest Moas first. This of course would have devastated the moa population way more than if it was the males who were the biggest

wasn't stygimoloch considered a separate species from pachycephalosaurus for the longest time only for paleontologists to realize stygimoloch and dracorex were probably female or juvenile pachycephalosaurus
I don't know about sex, but there is a theory that many of the smaller dinosour species are actually juvaniles of the larger ones. Which isn't so far fetched, when you realise how long it took us to figure out that all of the life stages of eels actually belonged to the same species.
Probably not that many, since you can tell a lot about the sex of a dinosaur from its bone structure, not to mention the dinosaurs of the same species that we have found both male and female specimens of. However, it wouldn't be far fetched to say this could be the case in some places, and there is a lot we are still learning about them.
As an aspiring botantist, the mechanisms flowers use to just *punch* pollinators with pollen amuses me to no end. Prayer plants (Maranta) have a similar mechanism.
Eclectus parrots are pretty extreme too. For a long time they thought it was 2 different species. She is red and blue while he is green and red. They are also polygamist the males have 4 to 5 girls on the go and the females have 6 to 7. This insures that if one parent dies there is more to take their place. The females also spend 9 months of the year in their tree hollows while the boys go out to find food and feed their girls. So she must be bright so her mates can see her while the boys have the duller plumage so that they can blend in with the ground better so as not to get eaten.
I’m not sure who coined the term “reverse sexual dimorphism” but I don’t think it’s accurate since sexual dimorphism applies for both sexes, doesn’t matter which one is bigger, if they have significant differences there is sexual dimorphism.
Isn't "parasitic codependent relationship" an oxymoron? afaik parasitic means, by definition, that the host gains nothing and/or is harmed by the relationship.
Parasitic: male takes nutrients from the female. Increasing his survival fitness while decreasing hers (granted, not a whole lot). Codependent: For their genetic fitness to be complete however, they need each other to create a next generation. Given their environment: their best chances are to stick together even though he's a blood-sucking leech and she takes away all of his free will... all to fulfill the urge to make babies... *Leaves quietly to reflect on past relationships*
so for Catasetum Orchids, you could almost say the bees are the 3rd biological sex: the pollinator, whose gender role is to deliver the seed from the male to the female, because neither the male or female Catasetum Orchid are able to move... an essential task in their species' reproductive system!!!
@@msr98111 which in adult, translates to a blood soaked rock, with flesh, viscera and blubber all over? Because that looks like it would take serious time.
I personally disliked the repeated misuse of the term 'parasite' here. Yes, on the face they have some traits of a parasitic relationship, and yet in both cases the female benefits as well by having a ready supply of genetic material to fertilize her eggs. 'Parasite' typically indicates one organism (generally unwillingly) benefiting at another's expense without contributing to the relationship. Other than that, another great video.
Parasitic under the "survival" scope. The male takes nutrients without offering her any assistance with survival. The male only seemingly becomes "symbiotic" at the end under the "evolutionary" scope... Otherwise his sperm isn't helping the host organism stay alive.
@@eriknicholas7294 Very true, very true. Though one could argue whether the males even truly survive, particularly in the case of anglerfish. Dissolution down to a few stray organs seems somewhat fatal. But then again, it still ensures the survival of the male's sperm at the female's expense. It's hard to lump these relationships into any real category since both parties get pros and cons from their biological imperatives. As always, the diversity of reproduction is so very weird and fascinating.
Scientist: "Look! I just made a nice, comfortable box that we can organize things into!" Nature: "... Nice try, but have you seen this?" Scientist: "Would you PLEASE stop thinking outside of our boxes?!"
Amazing, not only what nature does to insure the survival of a specie, but I truly enjoyed the way the video was explained. Excellent really enjoyable bit of knowledge.
Sinchoronizing between audio and subtitles in this video is almost perfect ; that is very important to me because I’m not english spoken. From Venezuela. Thanks
And there are still some people who say there's no evidence for evolutionary theory (or as they often butcher it, evolutionism or even evolutionaryism. Yes, I've heard it, and numerous other displays of ignorance).
4:05 - I probably would've been more taken aback and needed to do a double-take during that part if I didn't have a video I was editing literally in the next window where I made a very similar pun with that very bird.
This is really neat, what about male orangutans? They get phalanges SOMETIMES, like in a case where a Zookeeper was seen as an Alpha to one male and as the Zookeeper left on vacation the Orangutan developed phalanges. Interesting stuff. Crazy to think that just like us, they’re great apes.
Now this is getting more into the ideas of social epigenetics. Really cool and fascinating stuff. Switching parts of our genes on and off in reaction to our social environment. Like the spoon worm figuring out if it should develop into a male or a female, but not as extreme. Not sure how research has progressed, but there was a lot of talk of similar genetic reactions in humans. Maybe it could explain things like how we can make ourselves depressed just by the way we think. E.g. On the outside you're successful, popular and loved. But if you believe the opposite, you trigger genes that are associated with under heavy stress and threat. Then you become depressed.
Nice video! Earned my like, but I'm surprised they didn't include sexual dimorphism in lions. Besides the mane, males are 30-50% heavier than lionesses and have disproportionately larger heads
@@jacquejac1840 I was going to mention the group of lions that controls more land by appearing to have more males than they do, a lot of their females look male.
And one of the strangest mating rituals: humans, staying with one mate and usually only having one set of offspring. However recently, almost more than half of these couplings fall apart and the mates leave each other
It's not that strange, lots of animals mate for life but can have multiple partners if they 'break up' or one passes away. For instance species of penguins, ravens and eagles and other birds, it's very common. Many animals also invest heavily in very few offspring usually having one at a time that they keep with them for long periods, like elephants and dolphins.
That's not a recent thing. The idea of monogamy being a lifelong commitment is very new. Most relationships last between 1-7 years. Because that's how long it takes for a baby to be born and learn to run from predators. Humans weren't designed for monogamy, we have a strong sexual desire, even when pregnant. Which implies sexual behavior more similar to bonobo monkeys. Which form relationships easily, and have sexual relationships when ever, with who ever, for as long or as short as they feel like.

"Stays in its burrow and only comes out to reach for food then returns" *i feel attacked*
Do you also keep a bunch of male partners trapped in your house, and only give the minimal food, for the sole purpose of mating with you?
seems like in the easiest of times, people revert to their primal needs only. Youre forgetting endless masturbation that makes it all worse.

@@SilentBudgie What would be wrong with this?😕
I mean in a pandemic, it really helps to live that way, doesn't it? ^w^
"Parasite that lives in side your partner" that probably describes more than a few unhealthy relationships

Calling it "parasitic" is wrong here anyway because both sexes benefit from it.
