Manganese nodules as breeding ground for deep-sea octopuses
Alfred Wegener Institute (AWI)
Published: 19 December 2016
Deep-sea octopuses lay eggs on sponges that only grow on manganese nodules, making these nodules vital for reproduction. Their discovery at over 4000 m depth highlights ecological risks of seabed mining, as recovery from disturbances may take decades.

Researchers have identified distinct calls of Ecotype C killer whales in the Weddell Sea, recording over 2,000 sounds during a four-hour hunt. These unique vocalizations enable scientists to acoustically distinguish ecotypes in the Southern Ocean.
