Myth or miracle? Meet this aquatic creature who can change its sex, when needed!

Barramundi fish, native to northern Australia, possess a unique ability to change sex from male to female as they mature, a phenomenon known as protandrous sequential hermaphroditism. Research indicates that the timing of this sex change is closely linked to size rather than age; faster-growing fish transition earlier, becoming larger, more productive females that contribute significantly to the species’ reproduction.
