so the megalodon is most definitely extinct? how do scientists know?
well, the thing about large predators is that they leave an impact on an ecosystem big enough that you can tell they’re there, even if you never observe one directly. in this case, we know they’re definitely extinct because of the behavior of whales! whales used to max out at about 50 ft long and were fast and agile, entirely because of predation by megalodon!
but about 2 million years ago, our whales began to rapidly increase in size until we ended up with real monsters like the blue whale. this pretty directly lines up with the extinction of megalodon, and the removal of the pressure they were putting on large whale populations.
basically, large whales can get away with being gigantic, slow tanks in the oceans today because there simply isn’t a predator big enough to take them on anymore. if megalodon still existed, we would be seeing its impact on whale populations! whales would be smaller, and a hell of a lot more skittish than they are.
everything in a given ecosystem is connected, and you can often get important information about the unknown parts by observing the behavior of other parts of the ecosystem.
RomHun and PruHun <3 I'm in paradise
especially in vulnerable state
my biggest regret today...
finland is fuckin wild, i swear
my friends really got into hamilton recently… yes, in 2023
i am basically going through a lot rn… one more video that i saw when i was 14, one more ‘oui, oui, mon ami’ or ‘i will kill your friends and family…’ followed by a laughter & I. WILL. IMPLODE.
god is showing me my true image that i had the luxury of forgetting about and it’s sort of giving me an existential crisis
i have to live with knowledge that i was like that, truly terrifying
on the other hand… they’re so easy to impress
i really hope they won’t find out about hetalia though, yeah… i’d like to forget about that period of time permanently
Konrad walking around his cell and ranting about how he's equal to God and can change whole world with his poems be like:
