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].
