nauplius [′nȯ·plē·əs]
(invertebrate zoology) A larval stage characteristic of many groups of Crustacea; the oval, unsegmented body has three pairs of appendages: uniramous antennules, biramous antennae, and mandibles. Nauplius the plankton larva of numerous species of the family Crustacea. The body is unsegmented and has three pairs of appendages. In front of the mouth there are uniramous sensory antennules; in back there are biramous antennae and mandibles for swimming. The nauplius has a median eye. Between the mandibles and the anal opening there is a growth zone, where, as development progresses, the postnauplial segments with appendages develop. Want to thank TFD for its existence?

No references found | Other negative effects caused by low pH include reduced hatching rate and nauplius development in copepods (Kurihara et al. By carefully considering both nauplius and copepod development, they can compare across species as they describe variation in the number of stages of development, limbs and appendages, internal anatomy, behaviors, seasonal cycles and migration, ecology and mortality, and the patterning of the appendages of the copepods. Three different life-history stages (cysts, nauplius larvae, and adults) of brine shrimp Artemia salina were chosen as model invertebrate life stages to determine the effect of individual and combined treatments of sonication and advanced chemical oxidants under static and continuous flow regimes. |
