Nauplius
Definition:
(n.) A crustacean larva having three pairs of locomotive organs (corresponding to the antennules, antennae, and mandibles), a median eye, and little or no segmentation of the body.
Example Sentences:
(1) At this time development resumes, culminating in the hatching of free swimming nauplius larvae.
(2) At the nauplius 1 stage (24 hr) the enzyme appears in the brain and epidermal regions, as well as in mesenchymal cells, with weaker staining in the salt gland.
(3) Eggs and the earliest hatched stages, nauplius I-III were most sensitive to methoprene, with little mortality seen in the later stages.
(4) Dormant encysted embryos can be cultured readily in the laboratory to provide large quantities of free-swimming nauplius larvae.
(5) The archenteron was composed of presumptive naupliar mesoderm and the blastopore was located at the site of the future anus of the nauplius larva.
(6) Furthermore, when crude nuclear pellets from encysted gastrulae and developing nauplius larvae were mixed prior to sonication, subsequent solubilization of proteins from the mixture did not yield RNA polymerase activity; sonication of the pellet from nauplii alone resulted in the solubilization of large quantities of RNA polymerases I and II as we have previously found [1].
(7) The number of mitochondria in Artemia has been estimated at 1500 per diploid genome in the cyst and 4000 in the nauplius.
