TLDR
In failing to convulse at high pressure the amphipods from 4000 m differ radically in their pressure tolerance from those which live at depths down to 2700 m, a prediction derived from the responses of similar animals from lesser depths.About:

Adaptations to high hydrostatic pressure.
TL;DR: Comparisons of species from the cold deep sea with those from hydrothermal vents have shown that adaptations to both temperature and pressure play critical roles in determining the distribution patterns of deep-living species.

The Hadal Zone: Life in the Deepest Oceans
TL;DR: This book discusses the history, geology and technology of hadal science and exploration, ecology and evolution, and current perspectives in the hadal environment.

Pressure and life: some biological strategies
TL;DR: This review will focus on the consequences of pressure changes on various biological processes, and more specifically on animals living in the deep-sea, and recent data illustrating the diversity of effects pressure may have at different levels in biological systems, with particular attention to effects on gene expression.

Hydrostatic Pressure as an Environmental Factor in Life Processes
TL;DR: Hydrostatic pressure exists in all biological environments and in the deep sea the high pressure has elicited molecular modifications in the organisms adapted to live there, but the effects of micro-pressures manifest in the physiology of certain cells and the behaviour of many animals appear too small to arise from orthodox chemical reactions in solution.

TL;DR: A new sampling system which has been named PERISCOP and which has accounted for the selective capture and recovery of live animals from depths exceeding 2000 m, which is by far the deepest record for the pressurized recovery of a live deep-sea fish.

Depth-related enzymic activities in muscle, brain and heart of deep-living pelagic marine teleosts
TL;DR: The similar reductions in activities of both glycolytic (LDH and PK) and citric acid cycle (CS, MDH and IDH) enzymes with depth indicate that both standard and active metabolisms of deeper-dwelling species are reduced relative to shallower-Dwelling forms.

Scavenging abyssal amphipods from the North-East Atlantic ocean
TL;DR: A comparison of species of Paralicella and Orchomene based on morphological, developmental, reproductive and ecological characters indicates that the former genus are specialized necrophages whereas the latter are opportunist generalists.
Journal ArticleDOI
Metabolism of the abyssopelagic rattail Coryphaenoides armatus measured in situ
TL;DR: The metabolic measurements reported here for the rattail, Coryphaenoides (Nematonurus) armatus (Hector), at 3,650 m support the earlier findings of low respiration rates in deep-sea rattails and support the physiological axiom that respiration increases as a fractional power of body weight in animals.

Recovery and maintenance of live amphipods at a pressure of 580 bars from an ocean depth of 5700 meters.
TL;DR: Evidence suggests that food (fish bait) can have at least a 4-day residence time in the gut of these animals, and that the animals can easily tolerate decompressions of 29 percent and briefly of 70 percent of the value of 580 bars, the pressure of their natural habitat.
