"phallocentric" is this like when flatworms swordfight and the loser gets pregnant
Here's a tricky one. The online far-right absolutely can't remain silent at this moment. Like a shark, they have to keep posting or they'll die. And since they're getting paid to post, all the more so. But they can't risk really offending either party. So how to square the circle... I got it!

Getting real sick of getting one-upped by flatworms
Did you know that over the past year, most of your body has replaced itself cell by cell? Even so, according to biologist Alejandro Sánchez Alvarado, you've been one-upped by flatworms: buff.ly/ky5PM6u

Ooooh, yknow, I have been assuming these flatworms were the New Guinea snail eater ones, Platydemus, but I forgot there are some European springtail eater ones, Rhyncodemus. these might actually be those. I don't know if that's better or worse

Obama flatworms are not named after Barack Obama. it is entirely conincidental that I can say "I think my yard has Obamas"

Damn! As soon as the trilobites moved in, all the flatworms started screaming, "There goes the neighborhood!"

Men need to evolve into more sentient beings than flatworms.

This is a real mating behavior in many species of simultaneous hermaphroditic marine flatworms (polyclad flatworms, such as those in the genus Pseudobiceros).

I mean I know they're flatworms, but who wasn't telling me they also came in blue and gigundo size

There were lots of these very striking Turbellarian flatworms in my weekly plankton sample this week. They really jazzed up the Petri dish!

🪱 Biologist Alejandro Sánchez Alvarado loves planarians. To be fair, these tiny flatworms do embody the ultimate growth mindset: buff.ly/ky5PM6u

Worms I'm thinking about include sand striker worms, glitterworms, marine flatworms.

Cute Turbellaria alert! I love the eyespots of these little flatworms. Look in the comments to see an adorable portrait!

Alt text:

the video triumphantly announces that it is “Flatworm Friday” & shows many neon flatworms. 2 flatworms play an IRL game of Splatoon together. it becomes clear the flatworms are probably mating. the end of the video wishes you a good flatworm friday with a smiley face.
