It is as much diverged from the spiralian stereotype as the nemertean pilidium, with which Owenia's development indeed shares some traits, including enlarged first quartet micromeres, gastrulation by invagination into a large blas-tocoel, and the formation of a convoluted primary ciliated band from numerous proliferative cells.
The German Bight population was outstanding because of the lack of small/young animals below 3.7 g and 33 y, no detectable nemertean infestation (n = 18), and because of the highest (albeit not significantly different) recorded percentage of apneal phases (AP) (80%, Table 2).
Ten-day-old specimens of Paranemertes peregrina looked like young nemertean worms, each with an apical tuft and a short posterior ciliary cirrus.

The fact that nemertean predators exert a significant impact on the populations of their preferred prey has been documented for several nemertean species, primarily hoplonemerteans and heteronemerteans (McDermott, 1984, 1988; Nordhausen, 1988; Rowell and Woo, 1990; Thiel and Reise, 1993; Kruse and Buhs, 2000; Bourque et al., 2001, 2002; Van Son and Thiel, 2006).

Two species of orthonectids, Intoshia metchnikovi and Rhopalura pelse-neeri, have been reported to parasitize the nemertean Tetra-stemma flavidum (Caullery, 1961); but further morphological studies have suggested that both I.
