Clownfish or anemonefish are famous for being able to change their gender. The fish from “Finding Nemo” is actually a clownfish.
This fascinating species’ shelter is within an anemone: a sea flowing species. The clownfish usually don’t travel far from their home, but that doesn’t mean they have a problem with mating and keeping up with their reproduction. The clownfish has the amazing ability to change its gender. All clownfish are born male, but they can turn female, if needed.
When the queen female of a clownfish dies, another male takes her place. Usually the most dominant or the largest male in the school will turn female in order to sustain the population. Later another male will start mating with the now female clownfish. The clownfish are labeled as sequential hermaphrodites due to their remarkable ability.
There are also numerous other species, both terrestrial and sea ones, which have the same ability. However, one of the main reasons for the rare occurrence of hermaphroditism is the fact that it takes a great amount of time to complete the change.
