Venus' Flower Basket, Euplectella aspergillum, a glass sponge similar to those now invading Antarctic waters
Congrats fossil fuel industry, it's a sponge! Actually it's a whole bunch of sponges!
There is a surprising population explosion of Antarctic glass sponges over the past several years, according to a new study published today (July 11) in the journal Current Biology. Scientists, who had long assumed that these marine creatures grew very slowly, were amazed to find that the sponges doubled in biomass and tripled in number between 2007 and 2013. The research team, made up of biologists from the Alfred Wegener Institute (AWI), Helmholtz Center for Polar and Marine Research, conclude that the startling increase in glass sponges is directly linked to the 1995 collapse of the Larsen A ice shelf, when an area of about 770 square miles (2,000 square kilometers) fell into the sea.
“To the organisms living on the sea bed, the disappearance of the hundred-meter-thick Larsen A ice shelf must have been like the heavens opening up above them,” said project leader Dr. Claudio Richter. In surface waters now awash in sunlight, plankton can flourish, creating a constant rain of food onto the sea floor.

An iceberg in Antarctica recently broke off a glacier and is now floating freely in the ocean. What makes this so incredible is that the size of this icy mass is reportedly bigger than the city of Chicago.
