=== Nauplius larva ===

A [[fertilisation|fertilised egg]] hatches into a nauplius: a one-eyed larva comprising a head and a [[telson]] with three pairs of limbs, lacking a thorax or abdomen. This undergoes six moults, passing through five [[instar]]s, before transforming into the cyprid stage. Nauplii are typically initially brooded by the parent, and released after the first moult as larvae that swim freely using [[seta]]e.<ref name="Newman">{{cite book |last=Newman |first=William A. |chapter=Cirripedia |editor1=Sol Felty Light |editor2=James T.
