Discussion
- Males are supposed to differ from females by {p_Am} and E_Hp only
- The cost for milk secretion is added to the investment from the reproduction buffer
- Wwi is ignorned, due to inconsistency with Li
Facts
- length-weight: Ww in g = 0.00389*(TL in cm)^3.08 (Ref: fishbase)
- At first, they are enclosed in an egg case while the developing embryos feed on the yolk. After the egg hatches, the pup remains in the oviduct and receives nourishment from a milky secretion (Ref: fishbase)
