“…The anterior regeneration capabilities of two free‐living spionids ( Dipolydora quadrilobata and P. elegans ) have been studied in detail. When more segments were removed from these worms, they were slower at regenerating the segments (Lindsay et al 2007). Regardless of the number of anterior segments removed from members of both species, wound healing was observed, the formation of a blastema with a recognizable prostomium and peristomium occurred by 6 d after ablation, and worms eventually regenerated palps and anterior segments (Lindsay et al 2007).…”

“…Regardless of the number of anterior segments removed from members of both species, wound healing was observed, the formation of a blastema with a recognizable prostomium and peristomium occurred by 6 d after ablation, and worms eventually regenerated palps and anterior segments (Lindsay et al 2007). Members of D. quadrilobata regenerated nine to ten segments whereas members of P. elegans regenerated ten to 13 segments after an average of 29 setigers and an average of 32 setigers, respectively, were ablated (Lindsay et al 2007). Similarly, Stock (1965) showed that individuals of the spionids Dipolydora caulleryi (M esnil 1897), Dipolydora socialis (S chmarda 1861), and Polydora ciliata (J ohnston 1838) regenerated 10, 8, and 7 anterior setigers, respectively, following ablation.…”

“…Sublethal predation is common in marine environments and can influence the feeding behavior of polychaetes such as the spionids (Lindsay & Woodin 1992, 1995). Most spionids appear to have the ability to regenerate anterior segments, but at least one spionid ( Streblospio benedicti W ebster 1879) lacks the ability to regenerate even when only a single anterior segment is removed (Lindsay et al 2007). The spionids Dipolydora quadrilobata (J acobi 1883) and Pygospio elegans C laparéde 1863 have the ability to regenerate anterior segments and palps when five anterior segments, half of the segments with gills, and all of the segments with gills are removed (Lindsay et al 2007, 2008).…”

Abstract. The polychaete Dipolydora commensalis is an obligate symbiont of hermit crabs and produces a burrow along the columella of the gastropod shells they inhabit. Adults of D. commensalis have short palps that they use to feed on particles dropped or brought in by the respiratory currents of hosts. To determine whether hermit crabs influence palp length, specimens of D. commensalis were isolated in glass capillary tubes and the growth of palps was measured over a 3‐week period. Palp length was also measured in worms isolated in gastropod shells with or without hermit crabs for 2 weeks. In addition, to determine whether adults of D. commensalis have regeneration capabilities like those of free‐living relatives, worms were cut at the fifth or 15th setiger and then monitored for 35 d. Worms extracted from shells and placed into capillary tubes had initial palp lengths of 1.0±0.4 mm (n=17); after isolation, palps were 40% longer (1.4±0.4 mm, n=17). Worms in gastropod shells with hermit crabs had an average palp length of 0.9±0.4 mm (n=31), whereas worms in shells without hermit crabs had palps that were 33% longer (1.2±0.5 mm, n=40). Adults of D. commensalis are capable of regeneration; 35 d after ablation at setigers 5 or 15, the average number of anterior setigers regenerated was 5 (n=15) and 9±1.3 (n=13), respectively. The average number of posterior setigers regenerated from the 15 setiger anterior fragments was 11±6 (n=10). The findings suggest that the palps (and sometimes anterior ends) of the worms are exposed during feeding and are cut during movement of the hermit crab. In the laboratory worms can live for >4 years, considerably longer than the functional life span of most gastropod shells inhabited by hermit crabs.

“…A. C. Nicol, unpublished data in Wells 1952). Regeneration of feeding palps (following removal of only these structures) has been well documented in several genera of spionids (Hentschel and Harper, 2006;Lindsay et al, 2007;Lindsay et al, 2008), as has the regeneration of the operculum in serpulids (Okada, 1933;Szabó and Ferrier, 2014). Amputation and regeneration of parapodia has also been described in one species of nereid (Boilly and Boilly-Marer, 1995).…”

Animals differ markedly in their ability to regenerate, yet still little is known about how regeneration evolves. In recent years, important advances have been made in our understanding of animal phylogeny and these provide new insights into the phylogenetic distribution of regeneration. The developmental basis of regeneration is also being investigated in an increasing number of groups, allowing commonalities and differences across groups to become evident. Here, we focus on regeneration in the Spiralia, a group that includes several champions of animal regeneration, as well as many groups with more limited abilities. We review the phylogenetic distribution and developmental processes of regeneration in four major spiralian groups: annelids, nemerteans, platyhelminths, and molluscs. Although comparative data are still limited, this review highlights phylogenetic and developmental patterns that are emerging regarding regeneration in spiralians and identifies important avenues for future research.

“…Members of the third “superphylum,” the Lophotrochozoa, also sport a great variety of appendages, many of which are capable of regeneration. These include the arms, siphons, and sensory tentacles of molluscs (Lange, ; Chase and Kamil, ; Pekkarinen, ; Bobkova et al, ), and the diverse anterior appendages of annelid worms (Bubel et al, , ; Lindsay et al, ; Dualan and Williams, ). Such appendages play an important ecological role.…”
