If this video doesn't make you smile AND want to see manta rays for yourself then you have us stumped. They are an absolute sheer thrill to swim with yet we know very little about fundamental aspects of their biology and ecology. We don't really have accurate measures of their abundance, aspects of mating habits and breeding. We don't have much of a clue about their critical habitats, movements and migration pathways either. In fact as recently as last year we discovered a new species of giant oceanic Manta - one of the largest vertebrates discovered for decades. Despite this manta rays are being decimated in their thousands for their gill rackers to supply some forms of misguided Chinese medicinal therapies. Luckily we have a healthy population at Ningaloo yet people are still allowed to catch these animals in Australian waters. We think they are far better left swimming in the worlds oceans inspiring thousands of people in the future then being killed in their thousands helping nobody. Share this video if you agree and would like to see these animals protected in all our worlds oceans.
