Extracellular silk fibres in Stannophyllum (Rhizopodea: Protozoa)


The agglutinated shell or capsule of Stannophyllum zonarium, a deep sea rhizopod, contains a mass of extracellular proteinaceous fibres called linellae. They are 2–3 μm diameter, weakly positively birefringent and on examination by X-ray diffraction give an amorphous type of diagram. An amino acid analysis is notable for its very high glycine content and… (More)
