"The estuarine pipefish, has been playing a frightening game of hide-and-seek for decades. Not only was this pipefish thought to be extinct once, it was feared to have disappeared from the world a second time… only to be discovered yet again by scientists. You may wonder, just as we did, why this species has been lost and found so many times. What is it about this fish that makes it so vulnerable to extinction and why is it struggling to stay alive? Perhaps it is because this pipefish is very vulnerable to environmental changes or maybe because it is so rare?"
