They accumulate the bacteria through their food.
How can the mother pass on these bacteria to the young if they are accumulated by the food? If the animal is able to produce this type of poison what food is it eating to accumulate it? What food is there that both marine and land based animals eat that enables them to accumulate this poison? Your statement does not make sense, also I have not seen one article say it is accumulated through it's food, you seem to be the only one that thinks this so please explain a bit better how you have come to this conclusion.
All other named animals, like puffer fish or cone snails lose their venomous potencial over several weeks or months in captivity. If the blue ringed octopus is different in that aspect, then i apology. But so far i see no informations indicating that.
I haven't seen any infomation that they do lose their venom incaptivity
So far you ask me, how i as paleogeneticist can be interested in the venom production? Some Maniraptora used the very same methods to create posion.
I believe the only thing asked in this thread is to please elaborate on why you think your statements are correct with some sort of evidence to show why you believe what you do. I had stated that I do not understand how that being a paleogenticist gives you a major insight to what would be considered marine biology not why you have an interest in it.
