Some aspects of silica deposition in lithistid demosponge desmas

Microscopy Research and Technique, 2003
AbstractTransmitted light microscope and SEM observations of various growth stages, including very young forms, of lithistid demosponge spicules called desmas provided a wealth of new observations on silica deposition in desmas of most lithistid demosponge groups.
