Silica deposition is a fundamental process in sponges. Most sponges in the Classes
Demospongiae and Hexactinellida secrete siliceous elements, which can subsequently …

Marine sponges (phylum Porifera) form symbioses with diverse microbial communities that
can be transmitted between generations through their developmental stages. Here, we …

Le présent travail fait le point sur les progrès accomplis dans l'étude de l'écologie des larves
d'éponges depuis les excellentes rétrospectives des années 1970 et il souligne les …

One of the major questions in the evolution of animals is the transition from unicellular to
multicellular organization, which resulted in the emergence of Metazoa through a …

Ontogenetic changes in the photoresponse of larvae from the demosponge Reneira sp.
were studied by analyzing the swimming paths of individual larvae exposed to diffuse white …

Demosponges are considered part of the most basal evolutionary lineage in the animal
kingdom. Although the sponge body plan fundamentally differs from that of other metazoans …

We studied the abundance and spatial pattern of 2 Mediterranean enci-ust~ ng sponges,
Crambe crambe (highly toxic) and Scopalina lophyropoda (non-toxic), at 4 spatial scales …

Variability in the duration of the free-swimming period of lecithotrophic larvae of the
demosponge Sigmadocia caerulea (Hechtel, 1965) was assessed in the laboratory in the …

The larvae of many sessile marine invertebrates are able to locate and settle selectively in
physical microrefuges where the survival of the post-larval stage may be enhanced …

The mechanisms by which light elicits a phototactic response in sponge larvae remain
poorly understood. Here we investigate histological and behavioral aspects of the …
