postlarva
postlarva
1. Stage in the development of a bony fish between the resorption (see RESORB) of the yolk sac and the appearnance of juvenile characteristics.
2. The larval stage following the nauplius stage in Crustacea, and the one in which the full complement of trunk segments and appendages appears for the first time. The postlarvae of many crustacean groups are sufficiently distinct to have been given special names, e.g. megalops (crabs), and acanthosoma (sergestid prawns).
