having anti role models is a beautiful thing. it's not easy to live up to someone else's behavior but it is easy to lasso yourself into behaving right when you realize you're reminding yourself of the worst person youve ever met in your entire life

Uncharismatic Fact of the Day

Some people will tell you that millipedes don't actually have 1,000 legs, and that is true-- except for one species. Eumillipes persephone, a millipede found in Western Australia, has proven all the naysayers wrong; individuals have been found with an astounding 1,306 legs-- or 653 pairs! As a result, the scientists who discovered it gave it the name 'Eumillipes', meaning 'true thousand feet'.

Nearly blocked someone for a vaguely annoying reply they made in 2017 then remembered 2017 was 9 years ago. They will live. We can change *opens their blog* nevermind they got worse. Guards

"okay ❤️ yay ❤️" remains an unmatched response

pom pom crabs are some of the most unethical animals in the ocean

this man is a serial abuser

His pom poms are two sessile invertebrates he holds in his hands and starves so he can punch stuff with anemones who are so desperate to eat that they’ll use maximum sting on anything that gets close to him. When they starve to death he just finds more

ACTUALLY, IT IS WORSE

The crabs will force the anemones to clone themselves if one dies OR steal others’ anemones if both die

They haven’t found these anemones in their free-living form, so, as far as we know, this anemone species is these crabs’ slave species—it’s only known in association with pom pom crabs

Cool paper on this: Schnytzer, Y., Giman, Y., Karplus, I., & Achituv, Y. (2017). Boxer crabs induce asexual reproduction of their associated sea anemones by splitting and intraspecific theft. PeerJ, 5, e2954. https://doi.org/10.7717/peerj.2954

So if I understand this right, "slave species" is a biology term only used for this ONE SPECIFIC CREATURE OF ALL THE COUNTLESS LIVING ORGANISMS ON THIS ENTIRE PLANET?!

Oh, the slave species thing is outdated information from the original study in the 90’s. To be fair, that study is still very very respected, it was just wrong about this specific thing.

Their anemones aren’t a unique species, they are only visually distinct because the crab farms them in a very specific way - making a fragment of a larger hawaiian anemone, or finding a newly spawned one. When they carry it around, they force the anemone to adapt to an entire new lifestyle. The crab’s nocturnal behavior slowly kills the anemone’s photosynthetic symbionts, from which it gets its color. After that, the crab can control how much food the anemone actually gets by using it to mop up food off the sea floor, and take excess out of its mouth. Since it doesnt have to reach for sunlight, or reach to catch food, this encourages dense, but short tentacles.

The shortcoming of this study was just that its very hard to get the anemone away from the crab without killing both, and its equally hard to get an anemone to bounce back from this state.

Due to their introduction into home aquaria, we now know any anemone they take will end up in this state, (bubble tips, aipistasia, haitian anemones, the list goes on) and we also know they are not bound to carrying anemone’s specifically. They’ve been seen collecting zoanthids, palythoa, and euphyllia (though euphyllians usually don’t survive).

this is your captain speaking. do you guys remember 9/11 [escalating clamor of passengers freaking out] woah woah hey hey i was just curious. christ. am i not allowed to make conversation
