How does a nauplius larva change as it becomes an adult branchiopod?

A typical branchiopod begins its life cycle as a nauplius larva, characterized by a simple, unsegmented, triangular body and three pairs of appendages: the antennules, mandibles, and antennae, the latter of which are used for swimming.12

As the larva feeds and grows, it undergoes a gradual transformation into the adult form. This process involves the body becoming segmented, or jointed, and the development of additional limbs. The specific development of the antennae varies by order: in adult anostracans and notostracans, the antennae lose their swimming function, whereas in the other six orders of branchiopods, they remain large and functional throughout adulthood.2

It is important to note that not all branchiopods follow this larval development; some species, such as those in the order Anomopoda (e.g., Daphnia), bypass the free-living larval stages entirely, with the young emerging from the eggs as miniatures of the adult.12
