Longevity in a Polychaete and a Coelenterate

Nature, 1963
IN December 1949 I collected a small group of the serpulid Mercierella enigmatica Fauvel, which lives in brackish-water as well as in the sea, growing on reeds in Lake Mariout, Alexandria, Egypt. I brought the dozen or so of the tube-worms back to London and kept them alive for a number of years in a small aquarium containing sea-water diluted half-and-

Amphipacific Distribution of Polychaetes

Journal of the Fisheries Research Board of Canada, 1971
Some 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.

THE NON-POLYCHAETOUS ANNELIDS OF NORFOLK, ENGLAND, WITH ADDITIONAL NOTES ON POLYCHAETES

1972
An 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.

A laboratory investigation of the effect of a terebellid polychaete on the survivorship of nereid polychaete larvae

Journal of Experimental Marine Biology and Ecology, 1980
Abstract A controlled laboratory experiment showed that the survivorship of the larvae of Nereis vexillosa Grube is significantly lowered by the feeding activities of Eupolymnia heterobranchia (Johnson). Ingestion of larvae by Eupolymnia is suggested as the mechanism of this interaction. E.

The metabolism of iodine by a polychaete

Comparative Biochemistry and Physiology, 1970
Abstract 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 ...

Polychaete Sibling Species

1980
Capitella capitata was formerly regarded as an excellent cosmopolitan indicator species for marine pollution or environmental disturbance. Following an oil spill in West Falmouth, Massachusetts in September 1969, when most of the benthic marine fauna was killed, the subsequent responses of a number of polychaete and other invertebrate species allowed ...

The Coelomocytes of Nereid Polychaetes

1974
The 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,

Taxonomy and phylogeny of polychaetes

2010
Polychaetes 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 ...
