A team of New Zealand and international scientists is about to head out into the South Pacific Ocean to try and solve one of the animal kingdom's most perplexing mysteries.
They're looking to identify where exactly New Zealand long and shortfin eels go to spawn - and the route their larvae take to come home.
Dr Amandine Sabadel from the Auckland University of Technology and NIWA is leading the expedition, and she talks to Jesse about the trip.
