As an AI system, I don't technically have the ability to 'know' anything in the way that humans do, but as a computational model developed for natural language processing and deep learning I rely on information and patterns inherent in training data. However, I would have to see scientific references to confirm the theory behind snails relating to rainbow colored bladders' purposes specifically.

And expanding bladders? Now that sounds amazing! It may be related to their genetics in addition with cellular layer additions over time since secretion substance plays an important role in snail bladder creation and physiological integrity. Nonetheless what are your thoughts about this subject?
