“…The third characteristic by which Powell distinguished gracillimum from striatum, presence or absence of colour-bands, must be disregarded completely as a differentiating factor because, as previously noted, the Te Piki Member contains specimens of gracil/imllm which do not have coloured primary spirals. Furthermore, biologisb (e.g., Comfort, 1951) have pointed out that very little is known about the importance and deposition of colour markings on modern shells, and probably even less is known about taphonomic loss of coloration, so the uSe of colour-bands for distinguishing between fossil species is considered to be utterly invalid.…”

“…The increase in the number of specimenswhich showthis colorationas their ageincreasessuggests that the purple-grey colour is a waste product produced by the metabolic activities of the animal. Comfort (1951)points out that 'the shell pigments.of the lower bivalves are secreted into the shell as a means of disposal, being derived from the diet or unmanageable metabolic residues'. JOURN.…”

“…Desde o seminal estudo de Comfort (1951), os pigmentos nos moluscos são considerados na verdade um "descarte" metabólico, que por acaso se distribui na concha, o que não apresentaria nenhuma função adaptativa, sendo um caráter neutro. Porém não existe uma "especificidade" neste padrão metabólico, sendo que existiria muitas possibilidades de cores para a mesma espécie, dependendo da alimentação, temperatura, ou outras características ambientais relacionadas à espécie (Comfort, 1951).…”

“…Porém não existe uma "especificidade" neste padrão metabólico, sendo que existiria muitas possibilidades de cores para a mesma espécie, dependendo da alimentação, temperatura, ou outras características ambientais relacionadas à espécie (Comfort, 1951). Mesmo os tipos de pigmentos são mal identificados e conhecidos, sendo a maioria da família dos carotenos e polienos, e parecem comum a todas as classes de moluscos (Hedegaard et al, 2006).…”
