THE NON-POLYCHAETOUS ANNELIDS OF NORFOLK, ENGLAND, WITH ADDITIONAL NOTES ON POLYCHAETES
1972An annotated list is given of the Norfolk marine and brackish-water archian- nelids, oligochaetes, and hirudineans, based on more or less casual records ; none of these species are unusual in any way in the present context, and the only onepreviously found on the Norfolk coast was the skate-leech Pontobdella muricata.

Amphipacific Distribution of Polychaetes
Journal of the Fisheries Research Board of Canada, 1971Some 25 polychaete species common to Asiatic and American coasts are recorded in south-boreal and subtropical waters of the Pacific; they are absent in both northern cold regions (Bering and Okhotsk seas) and in tropical zones. Examples are also given of analogous, closely related twin species, and subspecies.

Taxonomy and phylogeny of polychaetes
2010Polychaetes are a large group of segmented worms that display an enormous morphological diversity. Molecular data has shown in recent years that groups previously thought to be separate from polychaetes are actually part of the group. The relationships within polychaete groups have been difficult to discern, and molecular data only partly corroborate ...

The metabolism of iodine by a polychaete
Comparative Biochemistry and Physiology, 1970Abstract 1. 1. Nereis diversicolor contains between 23 and 30 μg of iodine per g. 2. 2. Iodide is absorbed at about 5 ng/g per day under conditions approximating to the normal environment. 3. 3. Most of this is subsequently lost in mucus secreted, but 15 to 30 per cent becomes bound in the basal regions of the chaetae where tanning is ...

The Coelomocytes of Nereid Polychaetes
1974The coelomic fluids of most polychaetes, or marine annelids, contain numerous mobile cells which have phagocytic abilities. Many investigators have observed that coelomocytes of several species of polychaetes take up foreign matter and have suggested that they probably remove particulate wastes. This applies equally to nereids (Dehorne, 1922a,b; Romieu,
