  • data refer to colonies, which grow in leaves of constant thickness. Leaves consist of two layers of zooids and are formed when 2 encrusting colonies meet. (ref: Meno1975)
  • colonies are encrusting in the first year (ref: Wiki)
  • Both encrusting and leaf part form reproductive stages, which differ in morphology (ref: Blau2009)
  • Dry weight is roughly propto L^2. (ref: Meno1975)
