I was browsing through CoralRealm.com and came across an intriguing article stating that researchers have identified over 500 fish species that undergo sex change as adults. I find this phenomenon fascinating and would love to learn more about it. Can anyone here shed some light on this topic? How do these fish species go about changing sex, and what are the reasons behind this unique behavior? Any reliable sources or further reading recommendations would be greatly appreciated!
