=== Reproduction ===
Clam shrimp have different reproductive strategies. For example, within the family [[Limnadiidae]] are found [[dioecy|dioecious]] (male-female), [[hermaphroditic]] (only hermaphrodites), and [[androdioecious]] (male-hermaphrodite) species.

=== Life cycle ===
The eggs are surrounded by a tough shell and can withstand drying out, freezing and other hostile conditions. In some species these eggs can hatch after as long as 7 years.

When the egg arrives in a suitable pool, a larva hatches out at the [[Nauplius (larva)|nauplius]] stage (the nauplius stage is absent in Cyclestherida).<ref>{{cite journal | url=https://pubmed.ncbi.nlm.nih.gov/26486940/ | pmid=26486940 | year=2015 | last1=Fritsch | first1=M. | last2=Richter | first2=S. | title=How the cladoceran heterogonic life cycle evolved--insights from gamogenetic reproduction and direct development in Cyclestherida | journal=Evolution & Development | volume=17 | issue=6 | pages=356–366 | doi=10.1111/ede.12163 | s2cid=1932950 }}</ref> Clam shrimp nauplii are distinguished by very small front antennae. At the second stage ([[metanauplius]]), the larva develops the small shell. They develop very quickly. For instance, ''Cyzicus'' reaches sexual maturity in 19 days after hatching.
