Meet Bluey, the Transsexual Fish

Inquisitive, trusting, and friendly, New South Wales' favorite fish, the Blue Groper, has another trait that makes it special: the females can turn into males!

When a male Blue Groper dies, the largest and most dominant female will turn into a male fish to stabilize the population. "If you take a lot of males out," says Bob Harcourt, associate professor at Macquarie University, "then the females have to spend a lot of their time turning into males, which means they can’t breed and they can't lay eggs." This is getting to be a problem, because although they're protected, people are starting to overfish them illegally. Here's to hoping marine biologists figure out a way to protect Bluey and her/his kind!

The California Sheephead are also all born female and can turn into males. It's crazy cause the males and females actually have different body shape and color patterns, so it's quite a change! Nature is amazing!

Cute! It looks so happy swimming around, totally unafraid of the divers. Didn't know where was such anthropo-friendly marine wildlife aside from the dolphin. Quite upsetting that it too is a victim of the sportfishing industry. Sad how some people fail to understand that these are sentient beings and play a large ecological role in the homeostasis of the seas.
