Discussion
- males are supposed to differ from females by {p_Am} only
- mod_1: tL data added; data reviewed
- ab was found to be 1 yr longer that the reported 11 mnth by fishbase; cf the sawfish-species and the greenland shark
Facts
- mother feeds young in uterus with unfertilised eggs; oophagy occurs (Ref: Wiki)
- muscle temp = envir temp + 4; fishbase: preferred temp = 18.1 C (Ref: Wiki)
- length-weight: Ww in g = 0.00871*(TL in cm)^3.05 (Ref: fishbase)
