Eye comes round to say, show without any evidence it have which kinds of whale is OK to have which kinds of whale reach so difficult water area, other even marine mammal also are done not have.
Differ with fish, whale should be slipped into deep-sea, need solves breathing problem, say simply even if want to choke with resentment. The mankind chokes with resentment to have 9 minutes generally only, can achieve 45 minutes through what major trains, world record is 22 minutes (maintain by Stig Severinsen) , nevertheless this time is to be in underwater is motionless use up ability in order to reduce oxygen to achieve, this as normal in water as whale shift, preying is different. In addition, whale is in underwater, the problem such as the phreatic water disease when still needing to solve low temperature of area of hydraulic pressure, deep water, rise.
Long-term since, people thinks cachalot is to go all the time deep the deepest ocean is mammalian. The basis considers to discover, most cachalot can sink to forage into rice of the 300-800 in water, and go deep one the deepest once is created go deep 2250 meters record.
Whale is slipped into deep-sea later, need faces the problem of a decompression. That is to say, it did not rise to surface quickly on method horse, otherwise, the nitrogen inside the organization inside body circulates in blood of the block in blood-vessel, can bring about its to endanger life security because of decompression disease, no matter be submergence,still rise so, want to have a slow process. In order to go deep for the record of 2250, this cachalot used 2 hours to just finish this to go greatly.
Should come next of cachalot go deep throne lets virtuous, present record is maintaining is whale of rostellum of family name stalking or branch, of this kind of whale go deep record achieved 2292 meters, time is as long as 137 minutes.
Divide this both outside, very rare whale can undertake deep water dives. And even if is this both, also be apart from 6400 meters of apart very far. The difference of this kind of deepness, not be their effort any more, hold to what can overcome, should achieve this kind to go deep, need this kind of whale to have larger vital capacity, more able-bodied muscle in order to resist hydraulic, thicker adipose layer in order to maintain temperature. Very regretful, still have the whale of these a few kinds of advantages at the same time without discovery at present.
Can so other marine mammal leave normal life in 6400 meters of depth of water?
Be very sorry, the answer also is negative. Cowfish and dugong arrive rarely activity of deep water water area, and pinniped go deep champion is seal of power heart Er, it also can go to go to 600 meters or so greatly only.
So this hypothesis of the title falls in real environment cannot hold water, even if you convey instant of a whale to 6400 meters of depth of water, its viscera also is met by hydraulic collapse, it cannot maintain temperature, also cannot swim in time backwater face, death is a corollary.
