Most normal bug species ever.
No but seriously how do seadwellers work? Why do the lifespans get longer the higher up the hemospectrum you go? What's up with the different teeth? Do they have different diets? Is blood color determined by like, primary habitat????
Something interesting and kind of infuriating is that all the trolls in homestuck proper are mutants of some kind/clones of each other so we really never get a baseline for "normal troll" behavior or physiology. Aradia, Tavros, and Sollux all have psychic powers of their blood color, but we don't know how much they compare to the other members of the species and how common they actually are. Hiveswap/Friendsim implies that they are all abnormally powerful for psychics iirc. Sollux is explicitly kind of overpowered, and so are all the other goldbloods in the comic (all two of them!) because they are all genetic copies of sollux. what.
The trolls that aren't overtly mutants seem pretty isolated from the rest of society, such as nepeta living in a cave, terezi living in a forest, gamzee spending all of his time on drugs (how do troll drugs work???), and eridan and feferi seem kind of normal i guess but we also know virtually nothing about what would be normal for seadwellers since they are supposed to be very rare.
The other mutants:
Karkat- bright red blood
Kanaya- even before becoming a rainbow-drinker she is the only one that can go outside during the day without dying/being burned, and regularly does this
Vriska- vision eightfold, mind-control, and the ability to shoot webs i guess
Equius- why does he sweat so much. actually, how is it possible for trolls to sweat if they aren't mammals? also abnormally strong from birth
Anyways i impart upon you the wisdom that troll horns are similar to antenna and that trolls do in fact have paws. google image search "spider paws" theyre real (for best results look up "tarantula paws"). General rule is that the bigger the bug the bigger the paws and since trolls is bugs.... :3
please feel free to share your troll biology headcanons and speculations!!!! I love bugs!!!!
