I want to preserve octopus tentacles in a jar and the full baby octopus in another. I've been researching this on the internet for two months now. Every site has different information. I'd like the jars to last at least a year if not more. Here are some of the things I've found...which one is correct? -Place the octopus in a jar full of rubbing alcohol, seal it off -Soak the octopus in formaldehyde for a week, take it out, then place it in a jar of rubbing alcohol. -Place the octopus in a jar full of denatured alcohol Which one works? I've also read that with most of these methods you need to poke small holes in the animal, does this hold true for octopi?
