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.
They are fascinating little fellas.
