Watch a B.C. sea sponge shrink, sigh and sneeze in multi-year timelapse

Canadian researchers have released a time-lapse video of a sea sponge in B.C.'s Pacific Ocean charting changes from 2013 to 2015. Researcher Sally Leys says although it doesn't look very active on a day-to-day basis, once you speed the video up, her team noticed many changes that helped shed new light on ocean life.
