Like many other annelids, bearded fireworms, Hermodice carunculata, are capable of regenerating posterior body segments and terminal structures lost to amputation. Although previous research has examined anterior regeneration in other fireworm species, posterior regenerative ability in fireworms remains poorly studied. As the morphology of the anal lobe (a small, fleshy terminal structure of unknown function) has been used to distinguish East and West Atlantic H. carunculata populations, there… 

Myoanatomy and anterior muscle regeneration of the fireworm Eurythoe cf. complanata (Annelida: Amphinomidae)

Detailed investigation of adult body wall musculature and the parapodial muscle complex in amphinomids show that E. complanata bears well‐developed dorsal and ventral longitudinal muscle bundles as well as outer transverse muscles comparable to the pattern described for several Pleistoannelida.

Fireworms (Amphinomidae: Annelida) from Ascension and Saint Helena Island, Central South Atlantic Ocean

Morphologically, specimens from H. carunculata correspond to the West Atlantic population, while E. complanata specimens were clearly identified based on chaetal type and a genetic analysis will be necessary to elucidate the genetic connectivity across the Atlantic Ocean.

Rapid plastic responses to chronic hypoxia in the bearded fireworm, Hermodice carunculata (Annelida: Amphinomidae)

Fireworms exposed to hypoxia further reduced their rate of regeneration, but returned to normal regenerative rates after fifteen weeks under normoxic conditions, suggesting that morphological variation can be indicative of environmental conditions.

Tough, armed and omnivorous: Hermodice carunculata (Annelida: Amphinomidae) is prepared for ecological challenges

The bearded fireworm is best known for consuming live cnidarians, and has been implicated in transmitting coral pathogens, but it also feeds non-selectively on detritus, so it will be able to withstand many future ecological challenges and possibly contribute to coral reef decline.

Morphological investigations of posttraumatic regeneration in Timarete cf. punctata (Annelida: Cirratulidae)

This work investigates the redevelopment of body wall musculature and nervous system during anterior and posterior posttraumatic regeneration in Timarete cf.



Morphological comparison of the regeneration process in Sabella spallanzanii and Branchiomma luctuosum (Annelida, Sabellida)

Comparisons of the morphology of the regeneration process of anterior and posterior ends in Sabella spallanzanii and Branchiomma luctuosum, two sabellids that belong to closely related genera suggest that adults of S. spallanzai and B. luctUosum use different mechanisms to restore lost anterior body parts.

There is a need for published studies clearly documenting the lack of regeneration abilities in annelid species, and the review of regeneration data presented here is especially useful in highlighting annelids groups that possess both regenerating and non-regenerating representatives.

Experiments on anterior regeneration in Eurythoe complanata ("Polychaeta", Amphinomidae): reconfiguration of the nervous system and its function for regeneration

It is demonstrated that the nervous system is essential for regeneration: it induces cell proliferation in the blastema and subsequently in the regenerate.

The ventral nerve cord signals positional information during segment formation in an annelid (Ophryotrocha puerilis, Polychaeta)

It is demonstrated that the VNC plays an important role, not only in segment proliferation, but also in signalling positional information to the newly formed segments.


Examination of gut contents reveals that this species is probably omnivorous, and its digestive tract consists of five regions, a buccal cavity which is eversible, a muscular pharynx, a short oesophagus, an intestine which can be separated histologically into anterior and posterior regions, and a rectum.

The use of histology, molecular techniques, and ex situ feeding experiments to investigate the feeding behavior of the coral reef predator Hermodice carunculata, the bearded fireworm

Ex situ feeding experiments were conducted in Barbados to monitor organisms’ weight change in different coral reef feeding regimes as an indication of nutritional value of coral species and suggest H. carunculata may supplement their diet with other food sources to meet nutritional requirements.

The paper attempts to organize and correlate the known facts of annelid regeneration and investigates the question of anterior regeneration which is of most interest in annelids.

Revision of Hermodice Kinberg, 1857 (Polychaeta: Amphinomidae)

The type species, H. carunculata, has been redescribed, and H. formosa (Quatrefages, 1866) has been transferred to Pherecardia, and two new features have been included: the number of branchial filaments and the anal lobe.

Towards a revised Amphinomidae (Annelida, Amphinomida): description and affinities of a new genus and species from the Nile Deep‐sea Fan, Mediterranean Sea

Annelida, Amphinomida is a new genus and species from the Nile Deep‐sea Fan, Mediterranean Sea that has not been previously described and its affinities are unknown.
