Few people are aware that Australia has several species of sharks that will live in freshwater and this is one of them! The Speartooth Shark (Glyphis glyphis) is abundant in only localised and isolated regions and is subsequently considered Critically Endangered. The sharks in this clip were collected by the team at Cairns Marine, under special permit, for a strategic breeding program at the Melbourne Aquarium. As the only representatives of their species in captivity anywhere in the world, this is a vital step towards their long term species conservation.
