Do you know if Gedds are ever described, specifically on the Yeerk homeworld, to have the one too-short limb? I'm wondering if when the Yeerks were introduced to space travel and took a population of host Gedds with them, they didn't prepare enough for the effects of inbreeding. (though that also depends on Gedd reproduction/maturity rate. how long would they have to have been in a limited population to accumulate mutations. were yeerks trying to do gedd eugenics even before Seerow.)
We don't ever see the yeerk home world in canon — the closest we come is a hologram in Hork-Bajir Chronicles and Esplin 9466's attempt to recreate it from memory in Andalite Chronicles. So I feel like the gedd eugenics read is totally supported by canon, as is the interpretation that the yeerks somehow help "course correct" gedds while inside their brains.
It really makes the most sense if the yeerk ability to infest things was a form of tool use and that gedds are a) domesticated and (b) the yeerk world equivalent of working dogs
Idk, maybe gedds can see as well as they do because they’re domesticated/artificially modified critters. Like, every other lifeform described from their homeworld is blind.
I don't know if someone discussed this before, but do we know if there were any gedds on earth during/by the end of the invasion? If there were, what do we think happened to them after the war?
Maaan, I wish we had more intel on the gedds. It's possible that Aftran and Edriss are correct in their perception that gedds lack higher-order brain functions and genuinely benefit from symbiosis with yeerks... and it's possible that this is the same flavor of lie as humans telling each other that insects don't feel pain.
I sorta prefer the idea that it really is symbiosis, because then Seerow interrupts a fully-functioning ecosystem by infecting the yeerks with Andalite-Style Imperialism. And that fits with the themes of the series better. Whereas "there's no non-harmful way for yeerks to inhabit hosts" feels less on-brand.
That said... where does that leave the gedds? Maybe as hosts for yeerks who want to remain yeerks, but also want to leave the pool at times? Maybe they return to the homeworld? Maybe in some kind of protected Earth space, like the hork-bajir and taxxons? (If so, and if they don't have their own Toby or Arbron, I shudder to think about the risk of exploitation.) I'm torn, because the question of their sapience and independence is so unanswered.
Okay but it drives me crazy when people say that the Gedds and the Yeerks are symbiotic.
They are not mutually symbiotic. They are parasitic. The Yeerks themselves admit that. The text states over and over that the Gedds are enslaved, that they are afraid and abused by the Yeerks in just the same way that the Hork-Bajir and the humans are.
Some examples...

Rating of Aliens based on how well they can Throw
Andalites: Don’t even know what ‘throw’ is, completely unfamiliar with the concept of propelling an object unaccompanied through the air. Prefer running it over to you on their dainty little hooves.
Humans: Ability varies, but in general acceptable in distance, accuracy, and force. Do not in fact have a game where they propel rocks at opponents’ faces, but this concept is entirely in line with other activities that humans enjoy.
Hork-Bajir: Born to throw.
Taxxons: Why throw when you can eat?
Gedd: One arm is little, one arms is big, attempting to throw with either one will cause the Gedd to lose their balance and the object to roll sadly a few feet in front of them.
Yeerks: Nearest approximation to throwing is when a Yeerk uses a very strong echolocation pulse to move an object toward another Yeerk. Of course, as more of the universe is explored, Yeerks are finding more and more ways to propel objects.
Ellimist: Elllimists are not allowed to interfere in the lives of others, so any knowledge that they have of throwing is purely theoretical. They would absolutely never throw a planet out of alignment in order to change its climate. That is ludicrous.
Helmacrons: Researchers were sent to investigate this civilization, but have not yet returned. We do not worry for their safety, though, as we have received members of the Helmacron leadership as collateral. We expect their return any day now.
Iskoort: While it is acceptable for any Iskoort to ‘throw’ in the idiomatic sense (e.g. to ‘throw a party’ or ‘throw out the trash’), one must be a member of the Throwers’ Guild in order to participate in throwing literal objects. But don’t throw too hard, or the object may sail over the edge of the platform, a member of the Fetchers’ Guild will have to retrieve it for you.
