Abstract

The larvae of the deep-sea pandalid shrimpHeterocarpus fascirostratusYang, Chan & Kumar, 2018 were successfully hatched and cultured to the third zoeal stage. The larvae reached the third zoeal stage nine days after hatching at a water temperature of 21 ± 1 °C. Although members ofHeterocarpusA. Milne-Edwards, 1881 have rather diverse body forms and are often separated into many species groups, the early zoeal morphology ofH. fascirostratusfollows the general developmental pattern of the species inHeterocarpus.The main differences amongst these larvae are body size, spines on the anteroventral margin of the carapace, and the endopod setation of the third maxilliped.
