State
A survivorship curve plots survivors at each age interval: Type I when death concentrates late, Type II when even across ages, Type III when death concentrates early.
Show
Humans show Type I; birds show intermediate Type II; most fish show Type III with heavy early loss.
Watch for
Curve type correlates with parental care, but it measures only survival, not that cause.
