Hey so first off cool background, we can always use a better understanding of toxins.
Second off there are iirc over a thousand types of cone snails and a lot of them hunt very differently. The one i was referencing floods the waters around it with insulin (or an insulin like substance, im no biochemist) that paralyzes the fish its hunting so it can go in for the kill. As far as im reading you are referencing the snails that hunt in a rather more straightforward manner, using their terrifying harpoon. That would make sense as a matter of study, as im sure many a wayward footstep was met with a 'pooning.
Cone snails flood the water around them with weaponized insulin causing hypoglycemic shock, which i called a diabetic coma for comedic effect. So im pretty sure youre wrong here bud.
The real krebs cycle:
1.) Need to know what the krebs cycle is
2.) Look up what the krebs cycle is
3.) Use the knowledge for what you needed it for
4.) Forget the krebs cycyle until you need it again
Did they ever reveal how they stayed so solidly ahead? An especially good double agent perhaps?
