Abstract
In the adult state E. analoga occurs on sandy beaches along the west coast of N. and S. America in subtropical waters. The eggs which are carried by the [female][female] hatch to free-swimming zoeal larvae. All 5 zoeal stages are described, the first 2 from cultured material and the others from plankton collections. The larvae become widely dispersed by currents and somewhat larger numbers were taken at a distance of 60-80 miles off shore indicating most favorable survival conditions in these waters. This is probably correlated with the greater general plankton production taking place there. Most larvae occurred in July and Aug. Described also are the first and last zoeal stages of Blepharipoda occidentalis and the 1st zoeal stage of Lepidopa myops. The larvae of these 2 spp. are so distinctive that they cannot be confused with those of Emerita.This publication has 1 reference indexed in Scilit:
