adoral การใช้

Coiling becomes loose in the mature, adoral, part of the shell.
The mature shell is thickened on the inside just behind the aperture resulting in a constriction in the internal mold at the adoral end.
The genus is based on the forward, or adoral, part of the phragmocone with its proportionally narrow siphuncle that is less common for actinocerids.
It can be distinguished from its congeners by its thin body, an absence of cortical granules, and a low number of ciliary rows and adoral polykinetids.
The heterotrichs have an adoral zone of membranelles, but molecular and ultrastructure studies have shown they are a separate group that diverged from most other ciliates early on.
