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
  • DW in tL data are much larger than max DW of 72 cm given by fishbase. confusion with Aetobatus narinari?
  • mod_1: males have equal state variables at b, compared to females

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)
