An amazing video by nature photographer Daniel Stoupin reveals the stunning slow-motion world of corals and sponges. The three-and-a-half-minute "Slow Life" Vimeo video is composed of 150,000 shots, offering an astonishing insight into vibrant undersea life.

"Corals and sponges build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives," explained Stoupin, in a post accompanying the video on Vimeo.  "These animals are actually very mobile creatures, however their motion is only detectable at different time scales compared to ours and requires time lapses to be seen."

Each frame of the video is actually a stack that consists of between three and 12 shots where in-focus areas are merged, according to Stoupin, who runs the Microworlds Photography website. Stoupin, a doctoral student in marine biology at the University of Queensland in Australia, said that nine months of work went into producing the spectacular video.
