"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.

EDIT - answer to a common question: yes, colors are real, no digital enhancement, just white balance correction with curves. When photographers use white light on corals, they simply miss the vast majority of colors. Read more in my blog.
This clip, as well as stock footage, is available in 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. If you have a full-HD screen, when you enter full-screen mode, please press on "view actual size" next to the HD icon to improve sharpness.
To make this little clip I took 150000 shots. Why so many? Because macro photography involves shallow depth of field. To extend it, I used focus stacking. Each frame of the video is actually a stack that consists of 3-12 shots where in-focus areas are merged. Just the intro and last scene are regular real-time footage. One frame required about 10 minutes of processing time (raw conversion + stacking). Unfortunately, the success rate was very low due to copious technical challenges and I spent almost 9 long months just to learn how to make these kinds of videos and understand how to work with these delicate creatures.
