Microbial and sponge material were found in pockets in the active portion of the Tempus Fugit vent field (live clam at center).

Microbial and sponge material were found in pockets in the active portion of the Tempus Fugit vent field. Clams and a brachyuran crab are seen associated with the bacterial material.

Clam shells, riftia tube worms, and white bacterial mat material on rock surface.

At least two species of shrimp, yellow shelled mussels, a crab, and other life forms can be found in this image.

Siboglinid tube worms, a species not seen before on the Galapagos Rift, were found at Tempus Fugit vent field. A high density of limpets and a few shrimp are seen here also.

Riftia tube worms, smaller siboglinid tube worms, yellowish mussels, small white anemones, scale worms,limpets, and shrimp all seen in this diverse hydrothermal vent community.

Large broken clam shells, a live clam in the bottom right corner, yellow mussel shells, small white tube worms, and white galatheid crabs.

Carpets of small (inch-long) anemones covered rock faces adjacent to the active venting in the Tempus Fugit vent field.

Carpets of small (inch-long) anemones covered rock faces adjacent to the active venting in the Tempus Fugit vent field. A polychaete worm is also seen in the left center.

Clam shells, small white tube worms, small white anemones, and a large white-faced fish.

Riftia tubeworms colonize diffuse vent habitats between broken pieces of lava. Small mussels, less than two inches, were growing in cracks adjacent to vent openings (lower right).

Riftia pachyptila tube worms, small yellowish mussels in many of the cracks in the rocks, limpets, and shimmering warm water emanating from an active venting site.

Riftia tube worms colonize diffuse vent habitats between broken pieces of lava. Shimmering venting warm fluid is seen emanating upward through the tube worms.

Mussels, limpets and bacterial mat

Closeup of mussels with siphons extended for feeding. Limpets and a bristleworm are seen as well.

Large fields of mostly dead clams surrounded the vent field. Living clams were also seen among the masses of empty shells.

Carpets of small (inch-long) anemones covered rock faces adjacent to the active venting in the Tempus Fugit vent field. Is the large covered shell mussel or clam?

Closeup of dead giant clams Calytogena magnifica at Tempus Fugit vent field.

Extensive beds of the giant clam Calyptogena magnifica were found in in abundance at Tempus Fugit vent field. A grenadier cruises over the clam bed. A barnacle covered rock is in lower left.

Polychaete diversity; a scale worm clings to rock also inhabited by smaller feather duster worms.

Close-up of the 'plume' extending out of a Riftia pachyptila hard tube. The bright red coloring is due to complex hemoglobin within the plume used to transport oxygen through the worm's respiratory system. Note also the similar structure on the siboglinid tube worm just above the riftia tube worm.
