In this exquisite "macro symphony," underwater photographer Kay Burn Lim gives viewers a glimpse of the awe-inspiring creatures that live under the waves of Indonesia's Lembeh Strait, a passage of water between Lembeh Island and the mainland city of Bitung. The shallow strait is considered to be the premier muck diving capital of the world, and underwater photographers like Lim come from all over the world to document the wealth of creatures that lay hidden beneath these fragile sandy bottoms.

Lim's brilliant shots were captured with a Sony a7S camera encased in Nauticam underwater housing, and the final video is accompanied by the piano piece, "In the Moment of Inspiration," which was licensed and performed by pianist Doreen Kaw.

Vibrant sea life: Glittery eyed puffer fish

With the exception of the puffer fish (above) and the moray eel, all of the gorgeous marine critters you see in this video are no larger than two inches, and some of them are only as big as a grain of rice!

One of the most remarkable creatures featured in the video is the little leaf sheep nudibranch (Costasiella kuroshimae, pictured below), which is named for its obvious resemblance to, well, a sheep made of leafy greens! Measuring only a few millimeters in length, these tiny photogenic sea slugs spend their days grazing on ocean algae — and perfecting their pokémon-like cuteness.
