Dr. Avila´s question made me curious about development in
Volutidae. Many (or all????) have direct development. Posture is
made in large egg capsules, some attached to substratum, some
not. Some with only one embrio (like Melo?), some with just a
few.
I know of several papers by Penchaszadeh on Zidona (reproductive
cicle) and description of egg capsules of south atlantic
Volutidae. But whow abbout the rest of the family? Is it well
known? Any references to reproductive strategies of Volutidae???
