  • The female deposits her eggs and dies shortly thereafter, while the male remains in the tube to "incubate" the eggs (ref: MoorDill1993)
  • Larval development is direct via a non-planktonic metatrochophore larvae and occurs entirely within the parental tube; juveniles exit the tube 3 to 4 wk after egg deposition (ref: MoorDill1993)
