dc.description.abstract | Ecological interactions in the marine environment are now recognized to be partly held by chemical
cues produced by marine organisms. In particular, sponges are sessile animals thought to rely on
the bioactive substances they synthesize to ensure their development and defense. However, the
mechanisms leading the sponges to use their specialized metabolites as chemical cues remain
unknown. Here we report the constant release of bioactive polycyclic guanidinic alkaloids by the
Mediterranean sponge Crambe crambe into the dissolved and the particulate phases using a targeted
metabolomics study. These compounds were proven to be stored into already described specialized
(spherulous) sponge cells and dispersed into the water column after release through the sponge
exhaling channels (oscula), leading to a chemical shield surrounding the sponge. Low concentrations of
these compounds were demonstrated to have teratogenic effects on embryos of a common sea squirt
(ascidian). This mechanism of action called spherulization may therefore contribute to the ecological
success of encrusting sponges that need to extend their substrate cover to expand. | en_IE |
