The larval development from prezoea to megalopa and juvenile stages of Allopetrolisthes punctatus (Guérin, 1835) (Decapoda, Anomura, Porcellanidae)

ABSTRACT The external morphology of the larval steps in the development of the Anomuran crab Allopetrolisthes punctatus is described using material obtained under laboratory conditions and from field samples. All stages are presented with photos taken with a scanning electron microscope. For the fir...

The main difference between the zoeal stages is the translucid spine in the center of the telson of the zoea II, surrounded by five gross setae at each side.
