Abstract EN
The morphology, chemical composition, and optical properties of long monoaxonic spicules were studied in several species of marine deep-sea hexactinellid sponges of different orders and families: Asconema setubalense (Hexasterophora, Lyssacinosida) and Monorhaphis chuni Schulze (Monorhaphiidae).
Their macrostructural organization is a system of thin layers laid around the central cylinder containing a square canal filled with organic matter.
A significant role in spicule organization is played by the organic matrix.
The macrostructural of organization of the spicule in Monorhaphis chuni is a system of the “cylinder-within-a-cylinder” type.
However the spicule surface is covered with ridges.
They penetrate a few layers into the spicule.
Analysis of the elemental composition of the basalia spicule of Monorhaphis chuni demonstrates a heterogeneous allocation of C, O, Si on the spicule surface, subsurface layers, and on ridges.
All studied spicules have the properties of anisotropic crystals and they demonstrate a capability to the birefrigence.
On the other hand we discovered unique property of spicules—their capacity for triboluminescence.
The discovery of triboluminescence in composite organosilicon materials of which the spicules of hexactinellid sponges are built may contribute to the creation of biomimetic materials capable of generating light emission.
