During their reproductive period, females of Crepipatella dilatata deposit their embryos in
capsules that they then brood in the pallial cavity until juveniles emerge several weeks later …

Publisher Summary This chapter discusses the development and evolution of feeding
mechanisms in aquatic larval vertebrates, such as fishes and amphibians. Fish larva is the …

Plasticity in hatching potentially adjusts risks of benthic and planktonic development for
benthic marine invertebrates. The proportionate effect of hatching plasticity on duration of …

Planktonic larvae experiencing short periods of starvation or reduced food supply often grow
and develop more slowly, have poor survival, fail to metamorphose, metamorphose at …

It is argued that larviparous development has evolved at least eight times among extant
animals. A 'need for speed hypothesis' is proposed to explain profound convergence on a …

In marine invertebrates, polymorphism and polyphenism in mode of development are known
as “poecilogony.” Understanding the environmental correlates of poecilogony and the …

Many benthic marine invertebrates develop by means of free-living, dispersive larval stages.
The presumed advantages of such larvae include the avoidance of competition for …

The gametogenic biology is described for seven species of gastropod from hydrothermal
vents in the East Pacific and from the Mid-Atlantic Ridge. Species of the limpet genus …

Marine life histories differ from terrestrial life histories because seawater is denser and more
viscous than air, because desiccation is not a problem for organisms in water, and because …

Many biological facts are irreconcilable with the assumption that larvae and adults evolved
from the same genetic stock. The author of this book draws attention to these, and presents …
