Inside the acrylic sphere of the JSL submersible, Professor Mike Risk of McMaster University observes the coral habitat of Viosca Knoll. Quantifying the fauna of a bamboo coral, black coral, and anemone forest on the continental slope along a video transect, the JSL submersible encounters a school of Barrelfish, a Red Dory, and a Slimehead.

A Bibliography of All Known Publications & Reports on the Gulf Sturgeon Acipenser oxyrinchus desotoi (through 31 December 2013)
This functional bibliography is meant to be a complete and comprehensive bibliography of all discoverable reports containing information on the Gulf Sturgeon (GS). This bibliography contains all known reports presenting, documenting, summarizing, listing, or interpreting information on the GS through 31 December 2013.

Chemo Seep Biotope
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.

Anemones
An unidentified large white anemone densely populates thinly-sedimented goethite (iron oxide) slab rock, the fundamental Viosca Knoll substrate for attachment of sessile particulate-feeding invertebrates.

Wreckfish (Polyprion americanus)
Reaching a length of 1.5 m, the grouper-like Wreckfish (Polyprion americanus) is an apex predator living on deep reefs worldwide, and probably spawning on western Atlantic Lophelia coral reefs.

Squat Lobster (Eumunida picta)
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 guards a chemo-seep furrow.

Tinselfish (Grammicolepis brachiusculus)
Sculling along in triggerfish-fashion, the Tinselfish (Grammicolepis brachiusculus) hovers as brown dead Lophelia coral is collected, along with a pencil urchin (Cidaris rugosa) and patches of blue desmacollid sponge. With its tubular mouth permanently frozen open, the Tinselfish vacuums up small crustaceans living on Lophelia.

Coral Sampling
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.

Snowy Grouper (Epinephelus niveatus)
A characteristic predator on deep coral and rock reefs, the Snowy Grouper (Epinephelus niveatus) reaches lengths up to 1 m.
