The next stage is marked by the devlopment of first segment of the pleopods development. The mysis remain drifting in the water column until they metamorphose into post larvae within 10–12 days. Fig. 15. Migratory pattern burrowing species of shrimps. Fig. 16. NAUPLIUS STAGES

The posterior end of the nauplius consists of the future trunk -- it is short, undifferentiated, and unsegmented (Figure 1H). The nauplius larva does not have a complete digestive tract and does not immediately feed. It relies on stored yolk as an energy source. In some forms nauplius larva develops straight away into adult, but in many other crustacean forms it gives rise to other intermediate larval forms like metanauplius, protozoaea, zoaea, crypsis, mysis, megalopa, phyllosoma, alima; Metanauplius larva. It is the larva of Apus.

Development in the 1st naupliar stage is minimal, with only 3 pairs of appendages  This is also called the “umbrella stage” in which development of the nauplius is completed. Larval stages and growth. Larval development of Artemia has been  representing the last stage of the nauplius y described by HANSEN (1899). The connection between the types of nauplius y larva and the known cypris is at  stages of Eurytemora affinis (Copepoda, Calanoida) under different Nauplii develop faster and reach a higher developmental stage at 15 than at 10 jC,.

interpreted the nauplius as a specialized (or modified) protaspis. Lang (1946) argued that the protaspis larva with four pairs of appendages is not “an already spe-cialized larval stage”, but a primitive one, and that the first nauplius stage of crustaceans is a protaspis stage that is arrested and delayed in its development. Fortey

Naupli (nauplius is the singular, naupliar is descriptive), are the first and most commonly observed larval stage (image, left). Producing naupliar larvae is a characteristic often used to identify crustaceans, however there are a few groups that do not produce naupliar larvae.

The nauplius stage (plural: nauplii) is characterised by the use of the appendages of the head (the antennae) for swimming. The nauplius is also the stage at which a simple, unpaired eye first appears.

Because the nauplius stage is lost in several malacostracan taxa, the concept of the nauplius as a phylotypic stage of crustaceans is refuted. In addition, the nauplius as an example of the recapitulation of ancestral characters is discussed.
