博士 / 國立臺灣海洋大學 / 海洋生物研究所 / 104 / Although the predominately deep sea or cold water shrimp family Pandalidae has 191 species, there are limited studies on their larval development. The present work successfully describes the larval developments of 10 species in 3 genera from rearing experiment and collected from the field. Amongst them, the larvae of 8 species are reported for the first time. On the other hand, there are breakthrough in rearing duration and stages in 3 genera, with the species being Chlorotocus crassicornis (6 days to Z4), Heterocarpus abulbus (25 days to Z9) and Plesionika grandis (36 days to Z8). From the first confirmed Plesionika decapodid obtained from plankton samples in this study, it is suggested that Plesionika larvae undergo at least 13 zoeal stages with duration of more than 120 days. UPGMA analysis on 15 characters of the first zoeal stage now known in Pandalidae (33 species in 10 genera) does not support most of the genera as well as some suggested classification scheme from previous morphological analyses on adult characters in this family. However, the present larval characteristic relationships with a topology somewhat similar to recent molecular phylogenetic results related to Pandalidae. ASR analysis on larval characters reveals a reduction in pereiopod development and anteroventral margin of carapace becoming less spiny. Other evolutionary trend identified are abdomen becoming 6 segment, telson becoming fan like and pleopods becoming present in those species with abbreviated development.
