Pretty interesting find. (Not completely sure if this is the right community for this- let me know if you know where else it would be a good fit!)
there’s some snail that has an iron sulfide shell
the article doesn’t mention how corrosion is prevented, since iron loves to rust, also doesn’t link to a paper which could contain that information
The coating being orange indicates it is reacting with oxygen, aka rusting.
They aren’t shiny silver plated teeth.
rust of soft tho, it doesn’t like to bond with each other
Had to look this up yesterday as I had thought the same. In rodents anyway, the orange color is from amino acids, not the iron in their teeth.
Where did you find a source that it was from amino acids?
This one says the orange is from the iron
Wikipedia’s citationed summary confirms it is orange due to the the iron
They have four chisel-shaped incisors that continue to grow throughout their lives. The incisors are covered in a thick enamel that is colored orange or reddish-brown by iron compounds.
I thought about the rust too. Wouldn’t that mean their bite could give you tetanus on top of the hellish bacterial cocktail they have in their saliva?
