Each fish can attain a length of two metres and weigh at least one hundred kilograms. Although we know much about marine and terrestrial giants, the freshwater giants remain scientifically unexplored and unknown. In most cases, they inhabit unique locations. These fish are the "lions of the freshwater", supreme predators of their ecosystem, the complexities of which would collapse without their presence. Jakub Vagner appeared on The Tonight Show with Jay Leno.
In recent years, we have been focusing on expeditions to the Amazon River Basin in South America and to the Congo River Basin in Africa. We do not have a lot of time. Many of these wonderful creatures are close to extinction, fifty percent being on the verge of disappearing by the end of the century. Jakub Vagner and his team of experts have been conducting expeditions to all continents, excluding Antarctica. After many gruelling expeditions, sixteen of these fish, so far, have been mapped.
