Glass sponges take advantage of retreating Antarctic ice shelves
Date:7/12/2013

unknowns to make predictions. One example is the question of the influence of competitors: currently we are witnessing a fierce competition for space on the sea bed. Another concerns predators: in our dive in 2011 we hardly saw any of the snails and starfish, which feed on glass sponges. However, it is possible that these voracious predators will follow suit and wreak havoc."

Marine biologists at the Alfred Wegener Institute will continue to monitor the changes to communities in the western Weddell Sea. In January 2013, the planned dives in the area of the former Larsen A ice shelf had to be called off due to the solid pack ice in the Weddell Sea. However, Claudio Richter and his team hope for better pack-ice conditions during future Polarstern trips to this part of the Antarctic so that they can use new investigative methods to discover more about the life cycle of the glass sponges.
