, 2012 Crustaceans have to cyclically replace their rigid exoskeleton in order to grow. Most of them harden this skeleton by a calcification process. Some decapods (land crabs, lobsters and crayfish) elaborate calcium storage structures as a reservoir of ...

Phylogeny of freshwater crayfish [PDF]
, 1999 The phylogeny of freshwater crayfish, including both fossil and extant taxa, is assessed using morphologic analysis and nucleotide sequencing. Based on external morphologic characters, primarily characters of the carapace and appendages, the crayfish are
