All halibut are male until they reach forty-five inches in length, then they become female
Have you ever tried halibut fish? These fishes are a common meal for the northern regions of America. Most people consider them delicious. If you have ever eaten these, there is a strong chance that the fish was female. That is because after reaching a certain size, all halibuts become female.
Halibuts can be found in the North Pacific, North Atlantic, and Arctic Oceans. When they are born, they are all male, and they swim upright with eyes on either side of their head. However, when halibuts reach forty-five inches in length, they change their gender and get their characteristic look.
