“…Likewise, the same lander system observed the natantian decapod B. crenatus between 6007 and 7703m in the same trenches and the caridean prawn Acanthephyra sp. from 6007 to 6890m in the Kermadec Trench (Jamieson et al, 2009d). These decapod data are also consistent or comparable to other measurements of malacostracan crustaceans at much shallower depths (Neil and Ansell, 1995).…”

“…However, the first arrival time at 7703m of 50min (prior to the snailfish first arrival at 75min) and the arrival time of 15min at 6945m suggest that these isopods are of a reasonably high density at these depths. For comparison, reports of arrival times at hadal depths have been reported from 44 to 632min for fish (Jamieson et al, 2011), 18-180min for decapod shrimp (Jamieson et al, 2009d;Jamieson et al, 2011), 15-41min for princaxelid amphipods (Jamieson et al, 2012), 5-21min for lysianassoid amphipods (Jamieson et al, 2009c), 15-75min for munnopsid isopods and 80min for ophiurids (Jamieson et al, 2011).…”

“…In four video sequences at 6945m, the isopods exhibited three different escape responses in reaction to the presence of natantian decapods approaching the bait (Jamieson et al, 2009d): five backward jumps, three horizontal swimming bursts and two vertical swimming bursts (Fig.5). The backward jump escape was initiated when a decapod was within ~80mm from an isopod.…”

SUMMARYBenthic fauna in the hadal zone (6500-11,000m) rely on maintaining sufficient locomotory activity to exploit a low, patchy and uniquely distributed food supply while exposed to high pressure, low temperatures and responding to predator-prey interactions. Very little is currently known about the locomotory capabilities of hadal fauna. In situ video footage of the isopod Rectisura cf. herculea ( , respectively. These data suggest no significant reduction in locomotory capability despite the extreme depths in which they inhabit. These observations also revealed the isopod to be a bait-attending and aggregative species and suggest that it may not be obligatorily selecting infaunal food sources as previously thought.

“…Two deep-sea robotic vehicles, Nereus (USA) and Kaiko (Japan), have already reached the deepest parts of the Marianas Trench. To date, some of the most successful sampling has been with landers equipped with baited cameras and traps that have identified taxa not thought to occur at hadal depths (Jamieson et al, 2009). …”

The majority of the Earth is covered by ocean which itself averages greater than 3500 m deep. It is comprised mainly of the vast deep ocean plains, which span a depth range of 2000–6000 m. The maximum depth of the ocean however is nearly 11 000 m deep. These extremely deep areas are a result of tectonic plate convergence where an oceanic plate is subducted beneath a neighbouring continental plate. This subduction forms extraordinarily deep trenches which comprise what is known as the ‘hadal zone’. The hadal zone (6000–11 000 m) is therefore encompassed by clusters of disjunct and often extremely isolated deep trenches and troughs. The morphology of these habitats had provided a setting where environmental conditions (hydrostatic pressure and food supply) differ greatly from the majority of the deep‐sea and has resulted in high levels of species endemism at the greatest depths. Key Concepts: The deepest biozone in the oceans is the hadal zone (6000–11 000 m deep). The hadal zone is comprised mainly of deep trenches formed by tectonic convergence. The trench environment is characterised by high hydrostatic pressure, low temperatures, the absence of light and a limited food supply. Trench topography provides a unique setting with regard to food supply input because organic matter (food) is accumulated at the deepest trench axis. High levels of species endemism are observed in trenches as a result of their geographical isolation. Physiological adaptation to high pressure and low food supply is an essential prerequisite for survival in the trenches. Most metazoan taxa are represented in these deep trenches. Until recently, the technical challenges of studying the hadal zone were responsible for a dearth of information regarding the ecology at these depths. Research into the ecology of the hadal zone is in its infancy relative to shallower biozones.
