Tall bamboo coral trees (Keratoisis flexibilis) are surrounded by fields of unidentified large white anemones and orange-pink flytrap anemones (Actinoscyphia saginata). Small white 'gooseberry' anemones find a feeding perch right on the bamboo coral branches....

Much like Amberjacks on shallow reefs, fast and agile Barrelfish (Hyperoglyphe perciformis) patrol deep reefs in schools, preying upon squid, jellyfish, and small fishes....

Enormous fins spread wide enable the manefish (Caristius sp, probably C. maderensis) to drift motionlessly in midwater, here in the camouflaging company of a luminescent colonial salp. This specimen is the first record of the species in the Gulf of Mexico....

Areas of active, if subdued, hydrocarbon seeps are notably devoid of large sessile invertebrates. A fluffy gray biofilm coats the underlying rock, dotted with small white patches of the chemo-seep-associated bacteria Beggatoia....

Viosca Knoll is an elevated salt dome with dormant and active chemo-seeps. Where hydrocarbons are actively escaping from the substrate, dense clusters of tightly entwined vestimentiferan tubeworms grow. As the submersible approaches, it disturbs a Blackbelly Rosefish (Helicolenus dactylopterus), and...

Making a burrow in the stony base of Lophelia bushes, a 1.5 m long Conger Eel (Conger oceanicus) emerges from its hiding place to patrol its territory. It preys upon smaller fishes....

Small sprigs of glass coral are snipped off by the submersible's manipulator and transferred to a multi-chambered sampler for bacterial and genetic analyses. Attracted by the disturbance, a large Conger Eel (Conger oceanicus) then a Snowy Grouper (Epinephelus niveatus), investigates the scene....

Small Lophelia sprigs proliferate into a dense mass of white living branches, 1-2 m tall. Over time, groups of coral bushes coalesce to form massive reefs hundreds of meters across. Unlike shallow reefs built by many stony coral species, Lophelia pertusa reefs are generally formed by this single dom...

A true deep-reef denizen, the 3-4 m long female Ragged-Tooth Shark (Odontaspis ferox) navigates skillfully through Lophelia coral bushes. This specimen is only the second reported for the species in the Gulf of Mexico. The prominent notch in the first dorsal fin may be a wound received from a male d...

A regular and abundant inhabitant of western Atlantic Lophelia reefs, this red species of squat lobster with white-tipped chelae and legs perches atop rocks and coral fronds, pincers at the ready to instantly snag an unwary midwater fish that approaches too close. A more cyrptic long-armed relative ...
