The embryos of Harmothoë imbricata (L.) are protected during their early development as a mass under the scales of the female parent. Eggs are shed into the space under the scales through nephridial papillae which elongate and turn dorsally as the female matures. The mass is held together by an adhesive layer surrounding each egg. Maturation begins in September and breeding occurs during March and April, when each female spawns twice in succession. Males contain mature sperm throughout the… 

Population biology and larval development of the terebellid polychaete Nicolea zostericola

A 3-year study was conducted on a population of Nicolea zostericola at Nahant, Massachusetts (USA), which indicated that this species has a life span of about 1 year, with the entire intertidal population disappearing following the spawning season in late June, and reappears in September as a result of migration of worms from the sub-littoral zone.

Control of reproductive behaviour in the scale worm Harmothoë imbricata (Annelida: Polychaeta: Polynoidae)

The links between photoperiod, hormonal control of oogenesis and oocyte maturation, and the maturation hormone described recently in Harmothoë imbricata are demonstrated.

Some relationships between the process of pair formation and gamete maturation in Harmothoë imbricata (L) (Annelida: Polychaeta)

Male and female Harmothoe imbricata form pairs in preparation for spawning although the individuals are normally mutually antagonistic, due to a reduction in aggression shown by the females as they approach maturity.

Population Biology and Larval Development of the Terebellid Polychaete Nicolea zostericola

A 3-year study was conducted on a population of Niaolea zostericola at Nahant, Massachusetts (USA), which indicated that this species has a life span of about 1 year, and larval development is described along with juvenile and adult substrate preferences and behavior.

Small Size, Brooding, and Protandry in the Apodid Sea Cucumber Leptosynapta clarki.

The sequential hermaphroditism in L. clarki may additionally be a method to reduce inbreeding in a species with limited dispersal and allometric constraints may be avoided because of potentially low fertilization success and brooding within a distensible structure.

Dynamics of Egg Production in Mediterranean Populations of the Terebellid Polychaete Eupolymnia Nebulosa

The results confirm the occurrence of several peaks of jelly mass production at the population level and show that such peaks result from the production of several broods per individual female (the number of produced broods increasing with female size).

Gametogenesis in Harmothoe imbricata (Polychaeta: Polynoidae)

H. imbricata differs from most polychaete species so far described — where in males the spermatogonia divide mitotically to form rosettes after they have been released into the coelom, and in females the whole of vitellogenesis occurs after release of oocytes into theCoelom.

Reproductive biology of the deep-sea polychaete Gorgoniapolynoe caeciliae (Polynoidae), a commensal species associated with octocorals

The reproductive biology of G. caeciliae is consistent with that of most other polynoids including many shallow water species suggesting that phylogenetic history strongly shapes its biology.

Reproduction and development of three symbiotic scale worms (Polychaeta: Polynoidae)

The reproduction and development of symbiotic polynoid polychaetes in the genus Arctonoe were examined with light and electron microscopy, suggesting that geographic differentiation in host preferences is unlikely except over large spatial scales.

Reproductive Attributes of Polynoid Polychaetes from Hydrothermal Vents on the East Pacific Rise

Differences exist in the female reproductive anatomy, but all 4 vent polynoid species have sperm storage and lecithotrophic development, which contrasts with the reproductive strategies of most shallow-water polynoids, which have broadcast spawning and planktotrophicDevelopment.
