Aspects of the Postembryonic Development of the Mud Dragons Campyloderes cf. vanhoeffeni and Ryuguderes casarrubiosi (Kinorhyncha, Campyloderidae).

Cepeda et al., 2022 were studied by light microscopy. The investigation yielded important insights into the life history of mainly the former species, viz, (1) establishment of clear distinctive characters between late juvenile and female as well as more maturated male life history stages, (2) the principal developmental series of juvenile stages, (3) development of spines via anlagen and modified spines, and (4) dissolution of septa in the primary spinoscalids of the head during moulting.
