Reproduction
Goliath grouper are believed to be protogynous hermaphrodites, with individuals first maturing as females and only some large adults becoming males. Most grouper follow this pattern, but it has not yet been verified for the goliath. In fact, Bullock et al. found males could be sexually mature at smaller sizes (~1150 mm) and younger ages (4–6 years) than females (~1225 mm and ~6–8 years).

Famous quotes containing the word reproduction:

the only species that creates
gratuitous forms.
To create is divine, to reproduce
is human.”
