Surface Microornamentation of Demosponge Sterraster Spicules, Phylogenetic and Paleontological Implications

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 ...

Potential for host-symbiont communication via neurotransmitters and neuromodulators in an aneural animal, the marine sponge Amphimedon queenslandica

Frontiers in Neural Circuits, 2023
Interkingdom signalling within a holobiont allows host and symbionts to communicate and to regulate each other’s physiological and developmental states.

Mimicking the Ocean: Critical Challenges in Scaffold Design and Tissue Texturization for Cell‐Cultured Seafood

Journal of Food Science, Volume 91, Issue 6, June 2026.
ABSTRACT Cellular aquaculture offers a sustainable solution to global seafood demand, yet the production of high‐value, whole‐cut fillets is hindered by the “texture gap,” the inability to replicate the complex, anisotropic architecture of native fish muscle and its collagenous myosepta.
