The female genitalia have an enlarged dorso basal area of the eversible membrane that receives the enlarged lateral surstylus of the male.
The female raises her ovipositor and everts her aculeus from the eversible membrane and the male grasps it with his genitalic surstyli.

pharynx soft, unarmed, and lobed or digitated.
Because the beak joint of cephalopods represents the only muscle articulation examined thus far, the goal of this study is to begin to identify the general principles of support and movement in these joints by examining an example from another organism, a predatory schizorhynch kalyptorhynch flatworm with two beaklike hooks mounted on an anterior, eversible, and muscular proboscis.
Kalyptorhynchs possess an additional specialization: an anterior eversible proboscis that is separate from the midventral pharynx (Karling, 1947, 1949, 1950, 1961; Beauchamp, 1961; Schilke, 1970; Doe, 1976).
The larvae elicit tending behavior from ants through chemical communication originating from a pair of eversible
tentacles and, perhaps, other specialized epidermal glands (Pierce et al.
sigillata by the strongly developed eversible sac (weakly developed in C.

Mechanically, they are pressurized capsules with an attached eversible
tubule that is inverted inside the capsule before firing.
Cnidae are the eversible
secretory products of specialized cells called cnidocytes.
