Myogenesis of Malacostraca - the "egg-nauplius" concept revisited.

ABSTRACT:

Background

Malacostracan evolutionary history has seen multiple transformations of ontogenetic mode. For example direct development in connection with extensive brood care and development involving planktotrophic nauplius larvae, as well as intermediate forms are found throughout this taxon. This makes the Malacostraca a promising group for study of evolutionary morphological diversification and the role of heterochrony therein. One candidate heterochronic phenomenon is represented by the concept of the 'egg-nauplius', in which the nauplius larva, considered plesiomorphic to all Crustacea, is recapitulated as an embryonic stage.

Results

Here we present a comparative investigation of embryonic muscle differentiation in four representatives of Malacostraca: Gonodactylaceus fal
