<Li> Type III or concave curves have the greatest mortality ( lowest age - specific survival ) early in life , with relatively low rates of death ( high probability of survival ) for those surviving this bottleneck . This type of curve is characteristic of species that produce a large number of offspring ( see r / K selection theory ) . This includes most marine invertebrates . For example , oysters produce millions of eggs , but most larvae die from predation or other causes ; those that survive long enough to produce a hard shell live relatively long . </Li>
