Scientists have found what could be the largest fish nursery in the world.
The Weddell Sea located in Antarctica is ice-covered and beneath the ice is a breeding colony that contains 60 million fish.
The majority of nests were occupied by one adult fish guarding an approximated estimate of 1,735 eggs in each nest.
The fish that inhabit the area are notothenioid icefish. They are found in the Southern Ocean around Antarctica.
The fish are known to eat other fish but can also feed on krill.
