The bearded dragon is another animal capable of switching genders. Unlike the clownfish, these reptiles change while in the egg. This only happens if the temperature is warm enough during egg incubation. The males turn into females, but not so cleanly.
While they maintain male genetics, they go about their lives acting like females and reproduce like them. They even lay double the number of eggs as the typical female. And thanks to the rising global temperatures, the sex reversal is happening more often.
