Revision of Autolytinae (Syllidae: Polychaeta)

Zootaxa, 2004
Autolytinae is revised based on available types, and newly collected specimens. Out of 170 nominal species, 18 are considered as incertae sedis, 43 are regarded as junior synonyms, and 25 are referred to as nomina dubia. The relationships of Autolytinae is assessed from 51 morphological characters and 211 states for 76 ingroup-taxa, and 460 molecular ...

Functional Morphology of Eunicidan (Polychaeta) Jaws

The Biological Bulletin, 2017
Polychaetes exhibit diverse feeding strategies and diets, with some species possessing hardened teeth or jaws of varying complexity. Species in the order Eunicida have complex, rigid, articulated jaws consisting of multiple pairs of maxillae and a pair of mandibles.

Pigments ofChaetopterus variopedatus(polychaeta)

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1959
A chemical and histological study has been made of the pigments of the polychaete wormChaetopterus variopedatus. The conspicuous green colour of the gut in the middle and posterior regions is due to a green pigment hitherto known as ‘chaetopterin’, which is localized in small green spherules in the gut epithelial cells.

Evolution of interstitial Polychaeta (Annelida)

Hydrobiologia, 2005
An update of the systematics is given for the eight most important interstitial polychaete families: Diurodrilidae, Nerillidae, Protodrilidae, Protodriloididae, Saccocirridae, Parergodrilidae, Polygordidae and Psammodrilidae. Additional information and new observations are presented for the Diurodrilidae, Nerillidae and Psammodrilidae.

Phylogeny of Phyllodoce (Polychaeta, Phyllodocidae)

Zoological Journal of the Linnean Society, 1993
Abstract The phylogeny of 13 species of the polychaete genus Phyllodoce Lamarck is estimated from 23 morphological characters, totalling 54 character states. The genus is large, with over 100 nominal species, but, since both available material and descriptions for many species are inadequate, a smaller number of species was included in the analysis.
