Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux Open
Cilia are found on the epithelia of almost all metazoans, so their absence from the epithelia of all but one class of Porifera is puzzling. Homoscleromorph sponges possess ciliated epithelia, but their function and evolutionary history wit…

The chromosomal genome sequence of the sponge, Oscarella lobularis (Schmidt, 1862) (Porifera, Homoscleromorpha) and its associated microbial metagenome sequences Open
We present a genome assembly from an individual Oscarella lobularis (Porifera; Homoscleromorpha; Homosclerophorida; Oscarellidae). The genome sequence is 65.2 megabases in span. Most of the assembly is scaffolded into 20 chromosomal pseudo…

The Buds of <i>Oscarella lobularis</i> (Porifera, Homoscleromorpha): A New Convenient Model for Sponge Cell and Evolutionary Developmental Biology Open
The comparative study of the four non‐bilaterian phyla (Cnidaria, Placozoa, Ctenophora, and Porifera) provides insights into the origin of bilaterian traits. To complete our knowledge of the cell biology and development of these animals, a…

L’éponge marine Oscarella lobularis un modèle pour comprendre l’origine et l’évolution des épithéliums Open
Afin d’émettre des hypothèses sur l’origine et l’évolution des épithéliums, nous développons un modèle d’éponge appartenant à la classe des homoscléromorphes. Les éponges sont l’une des lignées ayant émergé le plus précocement au cours de …

Hyperaccumulation of Vanadium in animals: two sponges compete with urochordates Open
Vanadium (V) is the second most abundant transition metal in the oceans. Nevertheless, its concentration in organisms is generally low despite its involvement in various physiological or enzymatic functions. Because exposure to high concen…

Background Bilaterian animals today represent 99% of animal biodiversity. Elucidating how bilaterian hallmarks emerged is a central question of animal evo-devo and evolutionary genomics. Studies of non-bilaterian genomes have suggested tha…
