Biggest fish-breeding colony 🐟 Deep beneath the surface of Antarctica’s remote Weddell Sea, German researchers have discovered the world’s largest-known fish-breeding colony. Using a special camera-and-acoustic system towed by their ship on a cable along the seafloor—more than 1,300 feet below the surface—biologists from the Alfred Wegener Institute filmed an estimated 60 million Jonah’s icefish nesting densely across 92 square miles of ocean bottom. Given the colony’s biomass, the researchers say the size of this breeding area makes it an extremely important ecosystem within the sea. 🌊 Read more of the National Wildlife August-September Issue 📲 (link in bio) #wildlife #fish #breeding #science #ocean #ecosystem #sea
