What role do the antennae play in a branchiopod nauplius larva?

In the nauplius larva of a branchiopod, the antennae serve a primary role in locomotion, as they are used for swimming.1

Beyond their function in movement, the antennae also play a role in feeding. In many crustaceans, the antennae of the nauplius larva are utilized for both swimming and feeding, with processes at the base of these appendages assisting the mandibles in pushing food into the mouth.2
