I was looking up torsion in gastropods, and no other diagram so clearly explains the phenomena like this one does
Completely normal (if you are a snail at least).
When still just a tiny larvae, a gastropod’s mantle (the part of the body under their shell/“back”, it’s where most of their guts and organs are) will twist around 180 degrees, making their innards into a knotted mess.
Some types of gastropods (such as nudibranches) have actually evolved “detorsion”. After their larvae go through torsion their guts will actually de-twist partially or completely, leaving the adults with an anus not so damn close to their heads.
this is the face of someone who doesnt shit on their own head
Okay but WHY do they do this???? What purpose does it serve?
One hypothesis is that it helps position their gills/ sense organs to be facing forward instead of behind them. (cause like any reasonable critter their gills are usually positioned around their anus).
No one really knows at this point though. The benefits of twisting your guts and shitting on your head must be pretty good considering they have stuck with it for 500 million years, and behind only insects in terms of number of animal species.
Naruto: *starts a running sequence in the forest*
Me: OOO they’re about to explain something i could not infer with my own intelligence lets pay close attention
Kakashi, between 20 second long leaps from one branch to the next: *goes over their mission in painful detail*
Naruto, also defying gravity: What-? I dont understand ttebayo! What does that mean????
Sakura, suddenly getting serious: *explains what Kakashi just said only with more emotional depth*
Naruto, finally touching down on a branch: *frowns off into the distance* Sasuke….
does anyone else feel like they constantly have to justify everything they do? Iike I’m always mentally preparing a reason behind everything just in case anyone was to question it.
i only just realised that maybe that isn’t normal
