nauplius
Characteristic crustacean larval stage bearing median simple (naupliar) eye and 3 pairs of setose, functional appendages destined to become the antennules, antennae and mandibles [Brusca and Brusca, 2002].
Early larval stage having only antennules, antennae, and mandibles [Moore and McCormick, 1969].
Early larval stage with only 3 pairs of appendages, antennules, antennae, and mandibles. (Pl. nauplii) [McLaughlin, 1980].
Free-swimming, microscopal larval stage, after hatching from egg, chracteristic of penaeidean shrimps. (Pl. nauplii) [Butler, T.H.].
The larval stage that hatches from the egg of euphausiids. The first antennae are used as swimming appendages [Mauchline, 1984].
The minute, egg-shaped or pear-shaped, earliest larval form, into which many crustaceans, including penaeid shrimps, hatch from the egg. Higher shrimps, as well as lobsters and crabs, pass through the naupliar stage within the egg and hatch at a later stage of development [Bliss, 1982].
(Order Notostraca):
Early larval stage characterized by presence of only three pairs of appendages (antennules, antennae, mandibles) and unsegmented trunk. Certain tadpole shrimp hatch as nauplii. (See also metanauplius) [Stachowitsch, 1992].
(Order Diplostraca):
Early larval stage; basically characterized by three pairs of appendages (antennules, antennae, mandibles), although antennules are typically reduced. Some nauplii bear broad dorsal shield. (See also metanauplius) [Stachowitsch, 1992].
(Order Anostraca):
Early larval stage characterized by presence of only three pairs of appendages (antennules, antennae, mandibles) and an unsegmented trunk [Stachowitsch, 1992].
(Order Decapoda):
First of basically five larval stages (nauplius, metanauplius, protozoea, zoea, postlarva). Characterized by three pairs of appendages (antennules, antennae, and mandibles). Hatching from egg may take place at nauplius stage (certain shrimp-like decapods) or later [Stachowitsch, 1992].
(Subclass Cirripedia):
Early larval stage; characterized by frontolateral horns, nauplius eye, and three pairs of appendages (antennules, antennae, and mandibles). (See also cypris larva) [Stachowitsch, 1992].
(Subclass Copepoda):
A developmental stage whose somites do not articulate, with only three transformed limbs, and with an arthrite on the coxa of antenna 2. A naupliar arthrite may not be present on nauplii which do not feed. Nauplii are designated by Roman numerals [Ferrari and Dahms, in press].
(Subclass Copepoda):
The first larval phase, typically with three functional pairs of appendages (antennules, antennae and mandibles) [Boxshall and Halsey, 2004].
(Class Ostracoda):
Early larval stage after hatching from egg. Bears three simple appendages (antennules, antennae, mandibles) and is covered by carapace [Stachowitsch, 1992].
(Class Ostracoda):
First (earlier) of two basic stages in larval development (nauplius, copepodid). Characterized by presence of only three pairs of appendages (antennules, antennae, mandibles) and excretion by means of antennal glands. Typically involves five to six substages, the first two being referred to an orthonauplii, the remaining as metanauplii [Stachowitsch, 1992].
(Order Euphausiacea):
First of several larval stages (nauplius, metanauplius, calyptopis, furcilia). Characterized by three pairs of appendages (antennules, antennae, mandibles). See: cyrtopia [Stachowitsch, 1992].
