A clownfish begins life as a male and later transitions into a female. If the female disappears, the largest male will undergo a sex change and take her place.
A sex reversal occurs among this species when temperatures rise above 32°C, causing male chromosomes to develop as females, potentially boosting reproductive success in challenging environments.
In this fish, young females can permanently transform into males. These new males can mate with females and produce offspring.
These frogs develop according to their genetic sex during the tadpole stage, but under certain conditions, they can undergo a reversal and mature into adults of the opposite sex.
This adorable sea star is another species that begins life as male before transitioning to female as it grows between 9 and 16 mm.
