  • Drills holes mechanically and eats other molluscs; cannibalistic (ref: Wiki_nl)


  • Poor fit of tL data for neonates is likely due to the assumption of constant shap coefficient, while shape of veliger differs from that of the snail
  • Energy conductance was fixed to avoid very low values that match long incubation times; delay of start development is probably involved
