We help them survive

"Planet Earth is inhabited by many giant creatures. On land we can observe the rhinoceros, and in the sea, whales and sharks, but for a long time the giants of the freshwater remained unobserved. It is here that fish swim that attain unbelievable dimensions. They are rare, little known, and scientifically unexplored. We call them the Freshwater Giants – twenty four freshwater fish on our list who are fighting for survival."
