First, my guess is that this was a giant squid/octopus. They are a very secretive/seclusive creature that we still know very little about. Not too
long ago we actually learned that they may even school to hunt, so much so that some scientists have made a case for calling these pods or packs
because of the intelligence displayed more resembles that of mammals than of fish.
But back to the killer whale theory...
Perhaps if one wanted to pose the question, "How would it be possible for an orca to maintain the extreme depth, temperatures, and lack of oxygen for
two weeks?" a possible solution would be to look at other animals, even warm blooded, for a possible hypothesis to be disproved. In this case, we can
look towards the bear species and their hibernation patterns.
Hibernation (from Latin: hībernus, of winter) is a suppressed metabolic state that falls under the umbrella-term of torpor or dormancy. It is but one
of many forms of metabolic suppression. Hibernation is a widespread and common survival strategy expressed under the threat of a metabolic energy
crisis. Conversely and considering that some animals exist in this state for the greater part of the year, it could just as easily be considered the
default metabolic state and up-regulation of metabolism merely a response to the availability of energy.
Is it possible that whales can hibernate? Is it possible that in order to hibernate the whale requires the extreme pressure and temperatures. The last
thing most hibernating species do is take a large meal, which could provide hypothetical explanation as to why the wahale targeted such a large meal
to begin with. Scientists do know that whales can cover vast spaces of unbroken top ice and ice sheets. Maybe this explains how? They eat, use the
cool temperatures to force their body into dormancy, making them incredibly efficient with oxygen and calories, while they use the currents, and vary
depths, to carry them; in effect sailing instead of using their tail as the primary means of propulsion. Perhaps intense pressure could actually be
utilized by the whales lungs to more efficiently draw on it's last breadth of oxygen; getting use out of every available molecule of air.
That's the best hypothesis I can come up with to explain how this may be possible. It would certainly be a massive change in direction of how we think
about ocean mammals. But I'm still betting this was a squid.
Edit: This hypothesis could apply to all whale species... including sperm whales, who as far as we know so far can spend up to 90 minutes underwater
