THIS IS A a part of the most important fish-breeding floor but found. It occupies greater than 240km2 of the ground of the Weddell Sea, off Antarctica. Every nest is guarded by a notothenioid icefish, often the daddy. Altogether, there are about 60m nests, housing greater than 100bn eggs. The positioning was found by Autun Purser of the Helmholtz Centre for Polar and Marine Analysis, in Bremerhaven, and is reported in Present Biology. Dr Purser noticed the primary nests on a dive. Additional dives revealed extra. He and his colleagues then towed cameras over the positioning to find its full extent. One motive animals reside in crowds like that is to swamp predators. That may, although, backfire when the predator is a contemporary fishing vessel. For many years, there was discuss of constructing the Weddell Sea a protected space. Dr Purser has provide you with but another excuse to take action.
