Discussion
- End of acceleration is assumed to coincide with leaving the mother
- Egg production is assumed to occur once per yr
Facts
- the larvae stay in the mother incubation pouches during 8.5 months. After that, the juvenile (a little well developed sea urchin) goes outside; feeding situation inside the mother is not clear; possible epidermal uptake of DOM, Schatt et Feral 1996 (Ref: Scha1985)
