Fate of Microplastic Captured in the Marine Demosponge Halichondria Panicea [PDF]
Marine Pollution Bulletin, 2023 Microplastic particles are widespread pollutants in the sea and filter-feeding sponges have recently been suggested as useful monitoring organisms. However, the fate of microplastic particles in sponges is poorly understood, yet crucial for interpreting monitoring data.

Antifouling activity of twelve demosponges from Brazil [PDF]
Brazilian Journal of Biology, 2013 Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints.

Frontiers in Marine Science, 2020 Siliceous spicules in demosponges exist in a variety of shapes, some of which look like minute spheres of glass. They are called “sterrasters” when they belong to the Geodiidae family (Tetractinellida order) and “selenasters” when they belong to the ...
