2005), trichodinids are one of the most common parasitic ciliates that are well characterized by two main features: the morphology of the denticles in the adhesive disc and the development of the adoral ciliary spiral.

Lateral lips with two pairs of adoral setae (12), setiform, barbed.
Hypostome subrectangular in shape and cone shaped distally; with 4 pairs simple hypognathal setae (hg1-hg4) and 2 pairs adoral setae; with dot like lobes (Fig.
The arms were measured on the adoral (sucker-bearing) side, from the tip of the arm to the mouth.
Two pairs of setiform, curved distally, slightly barbed adoral setae (12-16).

Most annelid larval forms, feeding or not, can be readily related to the trochophore ground plan, which Nielsen (2001, 2004) defined as a larva bearing an apical tuft, a preoral ciliated band derived from trochoblasts (prototroch), an adoral ciliary zone, and postoral metatroch, gastrotroch, and telotroch, all of which bands consist of multiciliate cells with compound cilia.
Surprisingly, Pernet (2003) observed complete downstream-collecting ciliary systems with pro-totroch, adoral ciliary zone, and metatroch in larvae of the sabellid polychaetes Schizobranchia, Demonax, Myxicola, and Pseudopotamilla.
Surgical removal of the adoral lobe disrupts these and other settlement behaviors and delays the onset of metamorphosis in response to bio-film, providing experimental evidence that this region of the larva is specialized for functions other than increasing clearance rates or swimming speed.
