Evolution, Development and Regeneration of Fish Dentitions

Abstract

The diversity of fishes provides a wealth of morphological variety to investigate at the developmental and genetic level. The diverse range of phenotypes offered by fish dentitions provides an excellent comparative context for studies of evolutionary developmental biology. This chapter discusses the evolution, development and regenerative capacity of chondrichthyan and osteichthyan dentitions. We provide an overview of the recent insights into how general fish dentitions are initiated and how they continue to redevelop over multiple tooth generations.
