Deep-diving research submersibles require thick pressure hulls to survive depths sixgills inhabit freely.
At depths approaching 8,000 feet, water pressure exceeds 240 atmospheres, enough to crush many unreinforced structures. Sixgill sharks operate naturally in this environment, their cartilage skeleton and flexible tissues resisting compression.
💥 Impact (click to read)
Unlike air-filled organisms, sharks lack swim bladders, preventing collapse under pressure changes. Their physiology allows vertical movement across massive pressure gradients without catastrophic injury.
The same forces that demand engineering breakthroughs in human exploration are routine for sixgills. Their existence demonstrates biological solutions to mechanical extremes that challenge modern technology.
