Discussion
- The cost for milk secretion is added to the investment from the reproduction buffer
- mod_2: L-Ww data added, Wwb ignored due to inconsistency with LWw data; Ri reduced; Wwi, Lp increased
Facts
- Ovoviviparous. Myliobatiform stingrays, including the manta ray, sport "lipid histotrophy": the embryo grows to a large size in the uterus mostly by the lipid-rich "milk" secreted from the uterine wall (Ref: TomiToda2012)
