World's Largest Fish Nesting Ground With 60 Million Nests Discovered Under Antarctic Ice (Pics & Video)

The unexpected find is way larger than any other known colony of fish nests found so far. The fact that we know less about the ocean floor than we do about the surface of the Moon doesn’t make this incredible find any less surprising. Five hundred meters below the ice covering the south of Antarctica’s Weddell Sea, a research team recently discovered the world’s largest fish breeding site known to date.

Deep sea biologist Autun Purser of the Alfred Wegener Institute in Bremerhaven, Germany, and colleagues stumbled across the massive colony in early 2021 while on a research cruise in the Weddell Sea, which is located between the Antarctic Peninsula and the main continent. According to their findings, the icefish probably have a substantial and previously unknown influence on Antarctic food webs. Watch video here:
