Published: 22 December 2022
...Sarah B. Flensburg; Anders Garm; Peter Funch ABSTRACT Sponges (phylum Porifera) are metazoans which lack muscles and nerve cells, yet perform coordinated behaviours such as whole-body contractions. Previous studies indicate diurnal variability in both the number of contractions and the expression...

... the presence of the fine quartz dust (Min-U-Sil) added during the experiments except in a few small areas of the observed sections. Porifera host a great variety of microorganisms that in many cases develop mutualistic relationships with sponges, sharing part of the metabolic pathway ( Arillo et al...

...Danielle A. Ludeman; Matthew A. Reidenbach; Sally P. Leys ABSTRACT Sponges (Porifera) are abundant in most marine and freshwater ecosystems, and as suspension feeders they play a crucial role in filtering the water column. Their active pumping enables them to filter up to 900 times their body...

...Michael Nickel SUMMARY Although sponges (Porifera) are basal Metazoa without muscles and a central nervous system, they are able to locomote, which is generally correlated to drastic morphological changes. This behaviour has been known for more almost 150 years, but it is only partly understood...
