My all time favorite is that all sturgeon morph into females when they reach 6 feet.

Otolith: You are correct. There are fish species that do change. Sturgeon aren't one of them. They are what they are. Part of the reason people think that is the largest sturgeon generaly are female. Even though there is about a 50/50 split in the sex of oversize, the largest are usually female at least in weight because of egg masses.
