Nudibranch
When it comes to shapes and colours, the variations found in nudibranchs never ceases to impress underwater photographers – and the rest of us!
There are over 3,000 species of nudibranchs worldwide, with new ones being identified regularly. These fascinating creatures are hermaphrodites, meaning they can mate with any individual of their species. Another intriguing fact is that nudibranchs are carnivorous, with diets that go beyond corals, algae, anemones, and sponges—they may even consume other nudibranchs.
Nudibranchs in Indonesia
To help you get started, here are five fantastic nudibranchs to look out for in Indonesia:
Hypselodoris bullocki – This species, found in Bali, Lembeh, Triton Bay, Wakatobi, and Ambon, is famous for its lavender hue and dark spots. It’s a beautiful find for those who appreciate subtle but striking patterns.
Chromodoris magnifica – As its name suggests, Chromodoris magnifica truly stands out. You can find this bold nudibranch in places like Raja Ampat, Ambon, Halmahera, Lembeh, and Bali. Its eye-catching combination of orange, white, and black makes it a favorite for underwater photographers.
Nembrotha kubaryana – Known for its dramatic blend of black, green, and orange, Nembrotha kubaryana is another species divers love to spot in Wakatobi, Bali, Lembeh, Raja Ampat, and Alor.
Doto greenamyori – This unique species has earned the nickname “Doughnut Doto” because of its shape. Doto greenamyori can be found in Tulamben, Wakatobi, and Misool, often hiding among hydroids and other small organisms.
Thecacera pacifica – With its bright yellow color and black markings, this nudibranch resembles the famous character Pikachu! You can find it in Bali, Triton Bay, and Alor.
Please note: The above are the areas which offer a high chance of seeing these particular nudis. This being Indonesia, you can find the most unexpected species far outside their known range, for example:
– While diving with AMD-B, Dr Richard Smith (Ocean Realm Images) found displaying male McCosker’s flasher wrasses 2,500km east of their previously recorded range
– Okenia liklik nudis in Tulamben Bay, Bali (previously only recorded in Papua New Guinea and Luzon).
There are many other super-rare nudis that are scattered throughout the ocean so, who knows, maybe YOU will be lucky enough to find a new species and contribute to naming it 🙂
