metanauplius
A stage of development between the nauplius and calyptopis in euphausiids. A vestigial abdomen is present [Mauchline, 1984].
Developmental stage following the nauplius larval stage and bearing the same three appendages but having additional body segments [Brusca and Brusca, 2002].
Postnaupliar larva with generally same body and body shape as nauplius, but with additional appenages [McLaughlin, 1980].
Postnaupliar larva with same general body and limb morphology as nauplius, but having additional limbs [Moore and McCormick, 1969].
(Order Cladocera):
Larval stage at which certain predatory water fleas hatch; otherwise, metanuaplius is typically passed while still within egg [Stachowitsch, 1992].
(Order Notostraca):
Later larval stage between nauplius and adult. Earlier metanauplii bear only first three pairs of appendages (as in nauplii), yet exhibit further segmentation of trunk. Most tadpole shrimp hatch as metanauplii [Stachowitsch, 1992].
(Order Diplostraca):
Late larval stage; carapace typically first produced by metanauplius. (See also nauplius) [Stachowitsch, 1992].
(Order Anostraca):
Later larval stage between nauplius and adult. Characterized by gradual increase in number of segments and appendages [Stachowitsch, 1992].
(Class Cephalocarida):
Larval stage at which cephalocarids hatch. Includes a number of substages characterized by a gradual increase in number of segments and appendages [Stachowitsch, 1992].
(Order Decapoda):
Second of basically five larval stages (nauplius, metanauplius, protozoea, zoea, postlarva). Resembles nauplius, but bears additional appendages. Typically still contained within egg; if free-swimming, with antennal locomotion [Stachowitsch, 1992].
(Subclass Mystacocarida):
One of several substages in in development between nauplius and adult. Characterized by gradual increase in number of segments and appendages [Stachowitsch, 1992].
(Class Ostracoda):
Nauplius [Stachowitsch, 1992].
(Order Euphausiacea):
Second of several larval stages (nauplius, metanauplius, calyptopis, furcilia). Characterized by development of labrum and rudiments of maxillules, maxillae, and first thoracopods. See: cyrtopia [Stachowitsch, 1992].
