Abstract EN
The sessile suspension-feeding wormsnail Dendropoma maxima, Sowerby 1825 (Vermetidae) secretes a mucus net to capture planktonic prey.
The nets are spread out over the corals and often have remarkable deleterious effects on them like changes in growth form and pigmentation shifts not uncommonly resulting in tissue necrosis.
Until now, there is no explanation for this phenomenon although the indication as well as theories about its genesis is mentioned in several publications.
Vermetids are well studied concerning the intraspecific competition with neighboring individuals but not in their interaction with other taxa like corals or fish.
We did extensive in situ video recording and observed that fish avoided the plankton-load nets although several specialized taxa are known to be molluscivores, mucivores, and/or feed on plankton.
As many molluscs use chemical weapons to combat feeding pressure and to defend themselves against predators, we screened empty and plankton-load mucus nets for potential bioactive metabolites.
Bioactivity testing was performed with a recently developed system based on a chromatographic separation (high-performance thin-layer chromatography (HPTLC)) and a bioassay with luminescent bacteria Vibrio fischeri.
Thus, we found at least two active compounds exclusively accumulated by the wormsnails themselves.
This is the first record of bioactive properties in the whole family of Vermetidae.
