Distribution of Defensive Metabolites in Nudibranch Molluscs
Clear differences are highlighted in the storage of sequestered chemical defences, which may have important implications for species to employ effective defences against a range of predators. Expand
Chemical defense strategies in sponges : a review
Sponges, as well as other sessile marine invertebrates, share numerous ecological features with plants and have evolved similar strategies to defend themselves against threats from their bioticExpand
Chemistry of Glossodoris Nudibranchs: Specific Occurrence of 12-Keto Scalaranes
Interestingly, a population of G. pallida from Guam displayed a different scalarane pattern that was characterized by scalaradial (1), deacetyl scalarADial (2), and deoxoscalarin (3), thus confirming previous reports, and the specific occurrence of 12-keto-derivatives in some nudibranchs of the genus Glossodoris is discussed.

Comparison of anti-predatory defenses of Red Sea and Caribbean sponges. II. Physical defense
In addition to the commonly used chemical defense mechanism against predation, ses- sile organisms such as terrestrial plants, soft corals and seaweeds are known to have a physical defense mechanismExpand
Chemical defenses in the sea hare Aplysia parvula: importance of diet and sequestration of algal secondary metabolites
On Guam, the sea hare Aplysia parvula preferred and grew best when fed its algal host P. hornemannii, which is consistent with the hypothesis that diet-derived algal metabolites in sea hares play a role in deter- ring predation. Expand
Hemolytic compound 3,7,11,15-tetramethyl-hexadecan-1,19-disulfate found in the invasive European sea squirt Ascidiella aspersa
The solitary European sea squirt Ascidiella aspersa was introduced to northern Japan, causing dense coverage of the aquacultured Japanese scallop Mizuhopecten yessoensis . There are concerns thatExpand
The Validity of Brine Shrimp (Artemia Sp.) Toxicity Assays to Assess the Ecological Function of Marine Natural Products.
It is argued that the brine shrimp assay can reasonably indicate the potential toxicity of a compound to fish, but additional experiments with more ecologically relevant predators are required if a no dose-response is observed against Brine shrimp. Expand
Antibacterial scalarane from Doriprismatica stellata nudibranchs (Gastropoda, Nudibranchia), egg ribbons, and their dietary sponge Spongia cf. agaricina (Demospongiae, Dictyoceratida)
The structurally new scalarane-type sesterterpene 12-deacetoxy-4-demethyl-11,24-diacetoxy-3,4-methylenedeoxoscalarin was present in all three samples, supporting the dietary relationship between chromodorid nudibranchs of the genus Doriprismatica and scalaranes-containing dictyoceratid sponges of the Spongiidae family.

Bioactive Compounds from Marine Heterobranchs
Heterobranch molluscs are extremely interesting in regard to the study of marine natural products in terms of both chemical ecology and biotechnology studies, providing many leads for further detailed research in these fields in the near future. Expand
