are lost in appendicularians ([[Ferrández-Roldán and coll., 2021|biblio/34789899]]).
- A 3D reconstitution of hatchlings and jufeniles was done by SEM tomography by
[[Nishida and coll., 2021|biblio/33649401]].
+ - The brain of _B. stygius_ contains a number of cells comparable to the one of
+ _O. dioica_ ([[Zemann and coll., 2003|biblio/37313762]]).
