Planulae of the symbiotic hydroid Proboscidactyla flavicirrata settle on the rims of sabellid tubes by adhering sequentially and specifically to two different substrates. For both steps, nematocysts are the agents of adhesion. Although the cnidoblast

We tested the hypothesis that hooked setae function as anchors in three species of tubiculous polychaetes (Eudistylia vancouveri, Schizobranchia insignis, and Owenia fusiformis). All maintained position within their tubes when exposed to high pressur

The feeding currents produced by the branchial crown of the tube-dwelling sabellid polychaete Eudistylia vancouveri are compared with ambient currents experienced by the in situworm. The speeds of the branchial currents range between 0.025 and 0.080

Copper in seawater caused injury to the radioles (gills) of the sabellid polychaete, Eudistylia vancouveri. Light and electron microscopy showed the loss of cellular adhesion and the structural derangement that lead to cell necrosis and death. The pr

Chemically injured branchial pinnae of copper-treated polychaetes, Eudistylia vancouveri , regenerated while still exposed to copper. The first observations of pinna regeneration coincided with the apparent induction of a low molecular weight (∼500

Using X-ray Energy Spectroscopy trace metal concentrations (Ti, V, Mn, Fe, Ni, Cu, Zn, As, Pb) were measured in specimens of Eudistylia vancouveri (feather duster tube worms) collected from floating wharves near and far from a storm water outfall in

Three experiments with a sabellid polychaete (Eudistylia vancouveri) show the threshold concentration for increasing copper accumulation with time to lie between 3 and 6 micrograms/L total copper in seawater during winter conditions. The branchial cr

Allantoinase, an enzyme in the purine-urea cycle, was found in Eudistylia vancouveri (Polychaeta). The enzyme had a pH optimum at 7.6. The Km was 0.012 M allantoin, and the Arrhenius energy of activation was 12.6 to 14.6 kcal/mol.
