| Abstract: | To elucidate the embryonic and larval development of Phascolosoma esculenta, fertilized eggs of P. esculenta by artificial insemination were obtained and observed.. The processes of embryonic and larval development were observed, and the impact of salinity and pH value on the embryonic and larval development was investigated. The results indicated that the embryonic and larval development of P. esculenta undergo the following stages, i.e., zygote, cleavage, blastula, gastrula, trochosphere, pelagosphere, an... |
