nudibranch muck diving komodo

It’s no longer a secret that the Komodo, Indonesia, holds one of the richest and diverse marine population in the world. Over one thousand species of fishes and 250 species of coral reefs make up the underwater life in this part of Coral Triangle. Thanks to the Indian and Pacific ocean that spread in both sides of Komodo, streamlining nutrient-rich waters packed with planktons. The result is an explosion of colours; vibrant coral population with teeming fish swimming all around the water. However, one should not forget what happens on the ocean floor, where beauty lies on the details. Beneath what seems like soft sediment base and algae, small ocean creatures creeps undetected. Muck diving in Komodo might not be as big as venturing the iconic Batu Bolong or swimming with Manta, but it’s certainly an enthralling adventure to do in this spellbinding destination.

No muck diving would be complete without the tiny, bright, and colourful nudibranch. Nudibranchs are also known as the sea-slugs—but their appearance is far from boring from the land-slugs we know. They are known to display some of the brightest and strangest combination of colour; like purple-brown, brick orange-deep green, red-yellow, and many else! Their striking appearances are like glinting diamonds in the sands, however they are so small and well-camouflaged so you have to keep your eyes peeled to find them among the ocean litters.
