Ultrastructure of the earthworm calciferous gland. A preliminary study
Published online by Cambridge University Press: 21 August 2009
Abstract
The earthworm species belonging to the Lumbricidae family (Annelida, Oligochaeta) posses a complex oesophageal organ known as “calciferous gland” which secretes a concentrated suspension of calcium carbonate. Previous studies have demonstrated the non-crystalline structure of this calcareous fluid representing an interesting example of biomineralisation.
