Observations on the Nature and Significance of the Particles Used by Tintinnida during Lorica-Building

Evidence is found of selectivity for certain materials used in lorica-building, and there appears to be selection for particles according to size as well. There are striking differences in the proportions of biogenic:non-biogenic materials on the loricae of various specimens, and this appears to hav...

Description
Summary:Evidence is found of selectivity for certain materials used in lorica-building, and there appears to be selection for particles according to size as well. There are striking differences in the proportions of biogenic:non-biogenic materials on the loricae of various specimens, and this appears to have taxonomic significance. Certain species apparently produce the lorica in the sediments; the development of others appears to take place in the water column.
