“Slow” marine animals show their secret life under high magnification. Corals and sponges build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives. 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.

This clip, as well as stock footage, is available in UltraHD 4k resolution. Make sure you watch it on a large screen! You won’t be able to appreciate this clip or see individual cells moving in a sponge on a smartphone.

Talk about it!
