This chapter examines the origin and diversification of metazoan larvae and developmental
modes. It discusses the major features of larval evolution, and considers their developmental …

Publisher Summary This chapter discusses the role of larvae in the development and
evolution of invertebrates. The larvae of marine invertebrates are intricately functioning …

More than seventy percent of the earth's surface is covered by ocean-the home to a
staggering and sometimes overwhelming diversity of organisms, a majority of which reside …

Many marine invertebrates have elaborate feeding larval forms whereas others, sometimes
within the same taxon, have more. direct development. This contrast in development raises …

1. With the possible exception of inarticulate brachiopods, members of the oligomera
(brachiopods, ectoprocts, phoronids, hemichordates, echinoderms) do not reacquire a …

The extraordinary diversity of larval form and function in marine invertebrates has motivated
many studies of development, ecology, and evolution. Among organisms with pelagic …

The larval patterns of marine invertebrates pose intriguing questions for both evolutionary
and developmental biologists. However, combined investigations have been rare …

This chapter reviews selected aspects of the evolutionary ecology of marine invertebrate
larval types and how they relate to available life-history theory for marine invertebrate …

Modes of larval development play important roles in the ecology, biogeography, and
evolution of marine benthic organisms. Studies of the larval ecology of fossil organisms can …

Nearly all aspects of the life histories of individual marine-invertebrate species are
characterized by ranges of; sizes, seasonal variation, and functional flexibility and …
