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.

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.

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.

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.

Dorid Nudibranch Elaborates Its Own Chemical Defense
Science, 1983A biosynthetic experiment with mevalonic acid labeled with carbon-14 showed that the nudibranc Dendrodoris limbata elaborates polygodial, a sesquiterpenoid dialdehyde stored in the mantle, which constitutes its chemical defense against predators.

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.

Lowered nutritional quality supplements nudibranch chemical defense
Oecologia, 2002Reduced palatability through lowered nutritional content is a common defense for modular or gelatinous organisms, but commonly thought unavailable for active, mobile animals. However, nudibranchs - a group of brightly colored, shell-less snails - may supplement their chemical defenses via increased water and ash content.
