spoonworm การใช้

• This environmental sex determination helps Green Spoonworm populations respond to the availability of burrows.
• The sex of a Green Spoonworm is thus determined by external, environmental factors ( the presence or absence of bonellin ), not by internal, genetic factors ( chromosomes ), as is the case with most other sexually-differentiated organisms.
• ""'Bonellia viridis " "', the "'green spoonworm "', is a marine worm ( Class Echiura, phylum Annelida ) noted for displaying exceptional sexual dimorphism and for the biocidal properties of a pigment in its skin.
