This video of the Unseen Beauty of Slow Moving Marine Life is one of the most incredible underwater time-lapses you will see.
"Slow" marine animals show their secret life under high magnification. Corals and sponges are very mobile creatures, but their motion is only detectable at different time scales compared to ours and requires time lapses to be seen. These animals build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives.
