Molecular taxonomy and evolution in the family Stichopodidae
(Aspidochirotida: Holothuroidea) based on COI and 16S mitochondrial DNA.
However, most species in the holothurian families Holothuriidae and Stichopodidae
(order Aspidochirota) and Synaptidae (order Apoda) develop through the characteristic planktotrophic auricularia larvae (Sewell and McEuen, 2002).

Our examination of those studies, in combination with our own unpublished observations, leads us to suggest that the applicability of the tubule recruitment model is relatively limited in holothurians, even within the family Stichopodidae in which it was initially proposed.
In holothurians of the family Stichopodidae (30 species; Smiley, 1994) the gonad is present as two tufts of tubules, one on each side of the dorsal mesentery.
We conclude that the tubule recruitment model may be appropriate for a number of species in the aspidochirote families Stichopodidae and Holothuriidae.
