Discussion
- The cost for milk secretion is added to the investment from the reproduction buffer.
- Males are supposed to differ from females by {p_Am} and E_Hp only
Facts
- 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)
