Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972
Abstract 1. 1. The nudibranchs, Anisodoris nobilis, Dendrodoris fulva and Doriopsilla albopunctata, were found to contain unusually high percentages of carotenes in their integumental carotenoids. The first two fractions isolated in each case were identified as α-carotene and β-carotene, respectively. 2. 2.

Distribution of Defensive Metabolites in Nudibranch Molluscs
Journal of Chemical Ecology, 2018Many plants and animals store toxic or unpalatable compounds in tissues that are easily encountered by predators during attack. Defensive compounds can be produced de novo, or obtained from dietary sources and stored directly without selection or modification, or can be selectively sequestered or biotransformed.

Granular Chitin in the Epidermis of Nudibranch Molluscs
The Biological Bulletin, 2007Chitin is usually found in stiff extracellular coatings typified by the arthropod exoskeleton, and is not associated with the soft, flexible mollusc skin. Here, we show, however, that chitin in nudibranch gastropods (Opisthobranchia, Mollusca) occurs as intracellular granules that fill the epidermal cells of the skin and the epithelial cells of the ...

A phylogeny of Moorean nudibranchs with a test of nudibranch palatability
1994:A Phylogeny of Moorean Nudibranchs with a test of nudibranch palatability. A phylogeny for Moorean opisthobranchs is presented including twenty-one taxa and twenty-seven characters. The relationships between different taxa are explored and the value of characters discussed.

Chemical studies on Antarctic nudibranch molluscs
Italian Journal of Zoology, 2000Two opisthobranchs, Austrodoris kerguelenensis and Bathydoris bodgsoni, collected from Antarctica in the framework of Spanish and German expeditions, were chemically investigated in order to identify the skin secondary metabolites, probably involved in the chemical defense of these molluscs.

Active Nematocyst Isolation Via Nudibranchs
Marine Biotechnology, 2009Cnidarian venoms are potentially valuable tools for biomedical research and drug development. They are contained within nematocysts, the stinging organelles of cnidarians. Several methods exist for the isolation of nematocysts from cnidarian tissues; most are tedious and target nematocysts from specific tissues.

Nudibranchs: butterflies of the sea
International Zoo Yearbook, 1995Sea slug nudibranchs are exotic representatives of the Mollusca, rivalling orchids or butterflies in their beauty. Colourful nudibranchs are found in both tropical and temperate seas. Aquarium husbandry, as practised by the Seattle Aquarium, is presented here for temperate species.

Diterpenes from the Nudibranch Chromodoris luteorosea
Journal of Natural Products, 1990Three new diterpenes, luteorosin [1], 12-epi-aplysillin {2], and 12-epi-12-deacetoxyaplysillin [3], have been isolated from the nudibranch mollusk Chromodoris luteorosea, along with the previously known macfarlandin A [4]. Compounds 1--4 display ichthyotoxic activity; hence, they might serve as defense allomones.

The carnivorous nudibranch Roboastra tigris preys preferentially upon two nudibranchs,Tambja abdere and T. eliora, that in turn feed upon the bryozoan Sessibugula translucens. All four organisms contain tambjamines A-D (I-IV) that were shown to be fish feeding inhibitors. When attacked by Roboastra, T.

The Biology of Nudibranch Larvae
Oikos, 1963General interest in the problems of the larval biology of marine animals has increased greatly in the last few years. The importance of factors affecting the size of larval populations has now been recognized in its proper relationship to the size of adult populations. THORSON'S 1946 monograph on the larvae of Danish benthic invertebrates first brought
