Follicle cells are characteristically lacking during nemertean oogenesis, and in species such as Cerebratulus lacteus, Micrura alaskensis, and Par-borlasia corrugatus, numerous ovaries develop along the body, with each gonad producing dozens to hundreds of microlecithal oocytes that average 70-130 p.m in diameter (Stricker et al., 2001; Norenburg and Stricker, 2002; Grange et al., 2011).
The eggs are microlecithal, and they hatch at the zoeal stage with apposition eyes (P.
