Sulfur contents and sulfur-isotope compositions of thiotrophic symbioses in bivalve mollusks and vestimentiferan
The book consists of five detailed chapters on ecosystem-based management of marine microalgae and the bull kelp Nereocystis leutkeana, the ecology and management of temperate mangroves, the exploitation and conservation of precious corals, the biology of vestimentiferan
tubeworms, and historical reconstruction of human-induced changes in US estuaries.
Dan Cohen (NOAA Systematics Laboratory) studied the vent fish, and Meredith Jones of the Smithsonian Institution continued his earlier studies on the vestimentiferan
23 SCIENCE similarities in the distribution of animals at vent communities in the Pacific Ocean and in the gulf of Mexico, including the intriguing "co-occurrence" of a clam, a mussel and a vestimentiferan
, or tube, worm at widely separated sites.
These tiny gastropods were typically sampled as by-catch with the larger vent taxa, primarily bivalve molluscs and vestimentiferan
polychaetes, on which the limpets reside.
The links among these fields are illustrated by following an example species, the vestimentiferan
tubeworm Riftia pachyptila, through different stages of its life cycle.
Unlike endosymbiont-bearing vestimentiferan
tubeworms and vesicomyid clams, which have reduced or nonexistent digestive systems (Boss & Turner 1980, Jones 1981), digestive systems of bathymodiolin mussels appear to be anatomically and enzymatically complete (Kenk & Wilson 1985, Le Pennec et al.
In contrast, infectious symbionts such as the thiotrophs hosted by vestimentiferan
tubeworms (Nussbaumer et al.
Ridgeia piscesae Jones 1985 and alvinellid Paralvinella palmiformis Desbruyeres & Laubier 1986 were common on these rock fragments, whereas the mussels were few.
Seepiophila jonesi, a new genus and species of vestimentiferan

Life history characteristics and habitat-structuring by vestimentiferan
tubeworms from Gulf of Mexico Cold Seeps.
