“…The hydrozoids pass through the digestive system of the nudibranch without damaging it and are then concentrated in the body parts of the nudibranch, such as the cerata (Goodheart et al, 2017). Any animal that tries to bite one of these nudibranchs will receive a painful sting and will likely not come near it again (Ompi et al, 2019). The table above (Table 1) shows that 11 family nudibranchs found in northern Bali have various sizes ranging from small to large.…”

The presence or absence of certain types of carnivorous coralfish in a coral reef ecosystem accurately indicates the health of a coral reef ecosystem and the organisms associated with it; one of them is the nudibranch. This research aims to determine whether the presence of carnivorous fish in coral reef ecosystems affects the quality of the nudibranch life cycle and the distribution size in terms of predation. Nine carnivorous fish species were found at the three research stations, the largest group being triggerfish and grouper found in Lovina Reef and Menjangan island. Observed from the size distribution of nudibranchs, the presence of nudibranchs in the three research locations shows sizes ranging from small to large, namely from the Phyllididae nudibranch group. The dead body of the nudibranch was found in Tulamben reef, but it could not be confirmed whether the nudibranch was preyed by carnivorous fish. Carnivorous fish are not predators and do not affect the life cycle of nudibranchs observed from the complete size distribution of nudibranchs from small to large. Nudibranch predators cannot digest nudibranch bodies because their bodies are venomous; they use them as self-defense against the predators. Nudibranchia are not always found when preyed on by fish.

“…Triplek yang berisi substrat dibawa ke laboratorium untuk dilakukan pengamatan menggunakan mikroskop dan kemudian dilakukan identifikasi jenis-jenis makrobenthos berdasarkan klass, family, genus atau sampai ke jenis macrobenthos (Rupert & Barnes 1994;Hoff & Snell, 1997;Romimohtarto & Juwana, 2004;Ompi 2016).…”

The objectives of this study are 1) to Identify the specimen of macrobenthos attached to the substrate provided in 2 locations. 2) to determine the type of substrate attached by the larvae at both sites. 3) to determine the density of Macrobenthos attached to the substrate provided at 2 sites. A plywood plate had 16 holes with a diameter of 1 cm each that had been randomly filled with organic substrates, namely coconut fibers, palm fibers, shells with 'bysus' threads, and non-organic substrates in the form of plastic ropes. Each substrate has four replicates. The plywood plate with 3 replicates was placed in each station. The plate was removed and taken to the laboratory after 1 month. The identification up to family, genus, and species as well as the density of each species were applied. The results showed that not only the larvae of Septifer bilocularis attached to organic and non-organic substrates, but six species of larvae were also identified. The sizes of new settler macrobenthos from 2 mm to 1 cm attached on organic and non-organic substrates were identified. The density of new settlers species attached to substrates varied from 0.03 – 0.5 individuals/cm2. The new settlers identified 7 species in Tiwoho and 3 species in Malalayang. Keywords: Settlement, Substrate, Tiwoho Coast, Malalayang Coas. Abstrak Tujuan dari penelitian ini adalah 1) Mengidentifikasi jenis-jenis makrobenthos yang menempel pada substrat yang disediakan di 2 lokasi. 2) Mengidentifikasi jenis substrat sebagai tempat penempelan larva macrobenthos di kedua lokasi, dan 3) Menentukan kepadatan jenis Makrobenthos pada substrat yang disediakan di 2 lokasi. Triplek (plate) memiliki 16 lubang dengan ukuran diameter masing-masing 1 cm yang telah diisi secara acak dengan substrat organik yaitu serabut kelapa, serabut ijuk, cangkang ber ‘byssus’, serta substrat non organik berupa tali plastik. Masing-masing substrat ini memiliki 4 ulangan. Selanjutnya, plate, masing-masing dengan 3 ulangan ditempatkan di setiap intertidal, Towoho dan Malalayang. Plate diangkat setelah 1 bulan, yang dibawah ke laboratorium untuk foto dan diidentifikasi baik di tingkat jenis, genus, ataupun family. Hasil penelitian menunjukkan bahwa tidak hanya larva kerang Septifer bilocularis (Linnaeus, 1758), yang menempel pada substrat organik dan non organik, tetapi ditemukan larva macrobenthos lainnya, yaitu 2 jenis dari Cerithum egenum (Gould, 1849), dan Calcarina defranci d'Orbigny, 1826, 2 family/genus, yaitu: Canthocamptidae dan Portunidae, dan 2 klass, yaitu : Polychaeta dan Demospongae. Teridentifikasi jenis larva makro benthos yang baru menempel pada substrat substrat organik dan non-organik dengan ukuran yang bervariasi, yaitu dari 2 mm – 1 cm. Kepadatan jenis macrobenthos yang baru menempel adalah dari 0.03 – 0.5 individu/cm2. Ada 7 jenis teridentifkasi di lokasi Tiwoho, dan 3 jenis teridentifkasi di Malalayang Kata kunci: Penempelan, Substrat, Pesisir Tiwoho, Pesisir Malalayang

“…Tabel 1 dan Gambar 1 -12 dilihat bahwa famili nudibrancia yang paling mendominasi jika dilihat dari jumlah spesies adalah famili Chromodorididae. Menurut Ompi et al, (2019) famili ini memiliki distribusi yang sangat kosmopolitan atau penyebaran yang luas dan keanekaragaman paling banyak di wilayah tropis. Hal ini diperkuat dengan penelitian serupa pada penelitian Aunurohim (2010), Sari dan Aunurohim (2013), Ompi et al, (2019), Arifin et al, (2019), Purba (2013), Kusuma (2013), Pungus et al, (2017), dan Kaligis et al, (2018) yang mendata keanekaragaman nudibranchia di Perairan Indonesia mendapatkan famili yang umum ditemukan dan paling mendominasi adalah famili Chromodorididae dan Phyllidiidae.…”

Hal ini menunjukan bahwa kedua famili tersebut penyebaran luas di seluruh perairan Bali dan Indonesia yang merupakan perairan tropis, pada penelitian Chavanich et al, (2013) juga diketahui bahwa Famili Chromodorididae, Phyllidiidae, dan Discodorididae adalah famili yang paling dominan atau banyak ditemui di perairan Thailand yang kedalam perairan tropis (Laut Andaman dan Teluk Thailand).…”

Nudibranchia is the largest order of Opistobranchia which is known to have about 3,000 species. Nudibranchia is a popular macro photography object among divers. Although Tulamben Waters, Bali is one of popular destination for macrobiota’s habitat, but research on marine biota, especially nudibranchia in these waters is still very rare. This study uses two methods, which is direct observation to reveal diversity and species number, belt transect methods to estimate density or abundance per sampling area using diving techniques . A transect line of 50 m at each point of observation site was used to evaluate abundance. This study wants to see the level of diversity, mapping various species and abundance of nudibranchia. For biodiversity, 31 species from 15 families are found, Chromodoridae, Dorididae, Elysiidae, Facelinidae, Flabellinidae, Goniodorididae, Halgerdidae, Hexabranchidae, Phyllidiidae Polyceridae, Hydatinidae, Costasiellidae, Elysiidae and Limapontiidae. Whereas the transect method found 12 species from 6 families, Chromodoridae, Facelinidae, Phyllidiidae Aglajidae, Costasiellidae, and Elysiidae. With a diversity index of 2.27 and the highest level of abundance found in Pteraeolidia ianthina species with a relative abundance of 0.19%.
