Contraction Dynamics and Respiration of Small Single-Osculum Explants of the Demosponge Halichondria panicea

Frontiers in Marine Science, 2018
Sponges pump large amounts of seawater through their water canal system, providing both food and oxygen to the sponge body. Sponge pumping activity may show considerable variation as a consequence of contractile behavior, which includes contraction and ...

Swedish marine demosponge fauna (Porifera: Demospongiae) sampled 80 years after Jägerskiöld’s inventory

European Journal of Taxonomy
It has been 80 years since Leonard Axel Jägerskiöld’s thorough marine faunistic inventory of the Swedish west coast (1921-1938), which represents the latest update of the Swedish sponge marine fauna. In this study, we present an update of the demosponge
