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.

The first molecular phylogeny of cladobranchian opisthobranchs (Mollusca, Gastropoda, Nudibranchia)
Molecular Phylogenetics and Evolution, 2010The first molecular phylogeny is presented for the highly diverse, opisthobranch molluscan Cladobranchia. This study, the most comprehensive for Cladobranchia to date, used new sequences of two mitochondrial and one nuclear genes for 95 specimens from 22 families and 38 genera with a species of Pleurobranchoidea as outgroup. Although our results do not

Morphology of the buccal apparatus of Dendronotus frondosus (Gastropoda: Nudibranchia)
Journal of Morphology, 2023AbstractNudibranchia is the order of Gastropoda, which is known for its high diversity of dietary specializations and a diversified morphology of the buccal armature. The characters of the buccal armature are adaptive to the feeding mechanisms and diet preferences, but they also are phylogenetically informative.

The morphology of cerata and cnidosacs were studied in the nudibranch mollusk Pteraeolidia semperi (Bergh, 1870). Fine tubules arise from the gastrodermal channel of the digestive gland and contain cells with symbiotic algae (zooxanthellae). The cnidosac stores large kleptocnides. Thus, P.

Protective mechanisms in the Eolidacea (Mollusca Nudibranchia)
Journal of the Linnean Society of London, Zoology, 1966SUMMARY The protective system of eolid nudibranchs consists of crypsis, defensive behaviour patterns, autotomy of cerata, exudation of glandular secretions, ejection of nematocysts, and the structure of the epidermis. The existence of warning colouration has not been established.

On the genus Armina (Gastropoda: Heterobranchia: Nudibranchia) in Thailand
Marine Biodiversity, 2017The marine sea slug heterobranch fauna from Thailand is composed of a total of 240 species, and Armina semperi is the only representative of the genus Armina recorded in the country. This species, described in the Philippines in the nineteenth century, has an uneasy taxonomic history and appears to be part of a complex of morphologically similar ...

Progenesis in the evolution of the nudibranch mollusks genus Dendronotus (Gastropoda: Nudibranchia)
Doklady Biological Sciences, 2016The morphology and postlarval ontogenesis of the radula in 11 species of the genus Dendronotus Alder et Hancock, 1845, has been studied. Four types of radula are recognized in adult mollusks. Proposed evidence suggests that small species of Dendronotus have evolved by progenesis.

The Ecology ofOnchidoris Fusca[Nudibranchia]
Journal of the Marine Biological Association of the United Kingdom, 1970Opisthobranchs are mostly unsuitable animals for detailed ecological work since it is unusual to come across an adequate population for quantitative analysis. This difficulty is reflected in the generalized surveys that may be found described in the literature and which deal with a large number of species, each in little detail (Garstang, 1889; Swennen,

Spermatogenesis in Aeolidia papillosa (Nudibranchia)
Proceedings, annual meeting, Electron Microscopy Society of America, 1984Spermatogenesis was studied in Aeolidia papillosa by disection of the ovotestis. Morphologically, developing spermatogonia and accessory cells are similar to those described in Spurilla neopolitana except for spermatid development. Sperm also were examined for the presence of carbohydrates.

Diet of some Antarctic nudibranchs (Gastropoda, Opisthobranchia, Nudibranchia)
Marine Biology, 1989Austrodoris kerguelenensis feeds on sponges of the genera Rosella and Scolymastra; Aegires albus, on Hexactinellida (Porifera); and Tritoniella belli, probably on non-determined synascidians. Bathydoris clavigera and B. hodgsoni are omnivorous.
