Planktonic larvae, sessile adults. The life cycle of a barnacle has three phases: 1) a pelagic, suspension-feeding nauplius larva, 2) a pelagic, non-feeding cypris larva, and 3) a benthic (or attached, drifting) suspension-feeding adult. There are two main kinds of marine barnacles: goose barnacles (with stalk) and acorn barnacles (without stalk). Their legs develop into feathery cirri for filtering water. Their larvae (nauplius, cipris) can swim freely in water. The carapace of Cirripedia projects backward from the head, consisting of several calcareous plates enclosing the body. The pelagic phase of the barnacle life cycle consists of two larval forms.

Nauplius larva of a barnacle with fronto-lateral horns A fertilised egg hatches into a nauplius: a one-eyed larva comprising a head and a telson , without a thorax or abdomen. This undergoes six months of growth, passing through five instars , before transforming into the cyprid stage.

Barnacles reproduce sexually.

Description. Earliest and most basic type of a crustacean larva is the nauplius.; Development in the 1st naupliar stage is minimal, with only 3 pairs of appendages present – the 1st antennae, the second antennae and the mandibles.; During successive moults, trunk segments and additional appendages are usually added.; There is no segmentation of the body and a single eye (naupliar eye) in the Most of the 800 species of barnacles are very small. Barnacles start life as a free swimming larvae called a nauplius. The nauplius has an single-shelled exoskeleton, antennae, and six jointed legs. As it grows it molts and sheds its exoskeleton until it becomes a cyprid. The cyprid does not feed. It attaches itself to a rock or other solid surface using special cement glands in its antennae.

The nauplii of different species all look alike so they are hard to tell apart. These larvae live in the water column as part of the zooplankton.
