“…Annelids, commonly referred to as “segmented worms,” have remarkable abilities of whole‐body regeneration, even from few segments (Bely, , ; Seaver, ). Hence some species have been considered as excellent models to investigate regeneration, such as Alitta virens (Bakalenko, Novikova, Nesterenko, & Kulakova, ; Kozin, Filippova, & Kostyuchenko, ) , Capitella teleta (Hill, Ferkowicz, & Grassle, ; Jong & Seaver, ), Cirratulus cirratus (Weidhase, Bleidorn, & Helm, ), Enchytraeus japonensis (Myohara, Yoshida‐Nora, Kobari, & Tochinai, ; Ogawa et al., ), Eurythoe complanata (Müller, Berenzen, & Westheide, ; Weidhase, Bleidorn, Beckers, & Helm, ), Lamellibrachia satsuma (Miyamoto, Shinozaki, & Fujiwara, ), Platynereis dumerilii (Prud'homme et al., ; Starunov, Voronezhskaya, & Nezlin, ), Pristina leidyi (Bely & Wray, ; Nyberg, Conte, Kostyun, Forde, & Bely, ; Özpolat, Sloane, Zattara, & Bely, ) , Timarete punctata (Weidhase, Helm, & Bleidorn, ), and Typosyllis antoni (Aguado, Helm, Weidhase, & Bleidorn, ; Weidhase, Beckers, Bleidorn, & Aguado, ; Weidhase, Beckers, Bleidorn, & Aguado, ).…”

Regeneration mechanisms in Syllidae (Annelida)

Syllidae is one of the most species‐rich groups within Annelida, with a wide variety of reproductive modes and different regenerative processes. Syllids have striking ability to regenerate their body anteriorly and posteriorly, which in many species is redeployed during sexual (schizogamy) and asexual (fission) reproduction. This review summarizes the available data on regeneration in syllids, covering descriptions of regenerative mechanisms in different species as well as regeneration in relation to reproductive modes. Our survey shows that posterior regeneration is widely distributed in syllids, whereas anterior regeneration is limited in most of the species, excepting those reproducing by fission. The latter reproductive mode is well known for a few species belonging to Autolytinae, Eusyllinae, and Syllinae. Patterns of fission areas have been studied in these animals. Deviations of the regular regeneration pattern or aberrant forms such as bifurcated animals or individuals with multiple heads have been reported for several species. Some of these aberrations show a deviation of the bilateral symmetry and antero‐posterior axis, which, interestingly, can also be observed in the regular branching body pattern of some species of syllids.

“…After the incubation period, the lms were immediately xed with a glutaraldehyde solution and lyophilized using a freeze-dryer. The dried samples were subjected to surface morphology analysis using scanning electron microscopy (SEM) imaging (Miyamoto, Shinozaki, & Fujiwara, 2013, 2014Shinozaki et al, 2010).…”

Conventional marine-degradable plastics can remain in seawater for several years without losing their strength and stability, creating major environmental problems and threatening marine life. In this study, we prepared a cellulose nanofiber-reinforced starch film with pH-responsive weakening in seawater and marine-microbial degradability. The TEMPO-oxidized cellulose nanofiber (TCNF) was blended with hydroxypropyl starch (HPS) and di-aldehyde starch to develop a TCNF/modified starch film. pH-responsive swelling and weakening were performed in freshwater and seawater. Moreover, marine microbial degradability was evaluated in an artificial marine environment. TCNF/modified starch film rapidly loses up to 80 % of its strength in seawater and has higher marine microbial growth and degradability than TCNF film. The TCNF/HPS film demonstrates pH-responsive weakening with adequate microbial degradability. Therefore, it is a potential next-generation packaging material that can help address the problem of floating debris.

“…Annellids, especially marine polychaetes with a larval stage (trochophora) in their life cycles contain excellent regenerators, but regeneration can be low in some other species (Bely, 2006, 2010; Boilly et al., 2017; Chamorro, 2019; Goss, 1969; Kostyuchenko & Kozin, 2021; Myiamoto et al., 2014; Weidhase et al., 2015; Zattara & Bely, 2016). Numerous but not any species of annellids can regenerate entire segments of the body with the inner organs, including the head and the caudal region with the intestine.…”

Regeneration and regengrow in multicellular animals derive from the presence of processes of organ metamorphosis and continuous growth in their life cycles

The present review formulates an evolutionary hypothesis on the distribution of regeneration in invertebrates and vertebrates. Regeneration is a basal ancestral property of animals living in aqueous environment where life was generated. The specific life cycles that evolved in each phylum indicate that only adult aquatic animals with asexual reproduction, larval stages and metamorphosis, possess broad regenerative abilities, protostomes or deuterostomes. Regeneration derives from the re‐utilization in different forms of numerous developmental gene pathways active during development and the transitional phases of larval metamorphosis. An injured adult animal, composed of differentiated tissues, cannot repeat the same sequence of gene activation of embryogenesis, resulting in a variable regeneration (most aquatic invertebrates and anamiotes). In contrast, species with a genome that is not programmed for producing larvae and intense metamorphosis, mainly terrestrial (numerous nematodes, arthropods and amniotes), cannot regenerate their organs after injury. It is hypothesized that during the evolution of terrestrial animals, they lost genes involved in regeneration so that they repair by wound healing associated with grow (regengrow) or by scarring. Future molecular knowledge on developmental pathways that evolved in regenerating competent animals will tell us whether or not organ regeneration in regenerative incompetent animals will be feasible.
