I was able to place 8 of my cuttlefish with the UCSD research lab to help lower the cost of feeding them all. While the guy was over, he was mentioning that the sex of the cuttlefish is determined shortly after the eggs are laid and its based on the temperature the egg is maturing at. It was something to the effect of higher temperatures cause the eggs to hatch male, while lower temps hatch females (or visa versa). After he left I tried doing some research on that and wasn't able to find anything. Is this true? I ordered my eggs from blue world aquatics, so I'm hoping they are aware of how that works and raise the eggs at different temps to ensure different sexes (and ship different eggs to help make sure you get both sexes). I'm just hoping all this work isn't for nothing. I'd really hate to end up having all females or all males and not be able to breed them.
