The Last Song of the Cocolite

The Last Song of the Cocolite



Margarita Kovtanyuk, Department of Structural Biology, Weizmann Institute of Science, Rehovot


SEM micrograph of coccolite remains on surface of the gizzard plate of cephalaspidean gastropod mollusk Philine aperta. As the vast majority of Cephalaspidea lack teeth, their digestive tract possesses a muscular oesophagal crop, the gizzard, which incorporates calcareous masticatory plates acting as a millstone which crushes injected food items. This SE image was produced by an InLens-detector of FEG-SEM (LEO-Supra-55VP). Working conditions: EHT 3kV, WD 2mm, Aperture Size 30μm.
