and the NOVA website has a very nice article on crocdilians that
discusses that alligators can keep alive while frozen in ice as long as
they can breathe in their NATURAL ENVIRONMENT........

OUTLASTING THE DINOSAURS
(Dr. James Perran) Ross: <snip>
There is another element. Crocodiles, for all their ability to get their
body temperature up when they have sunlight, do very well at low body
temperature in the darkness. All their systems continue to work
adequately well. <snip>
It depends a great deal on the species, but the three species that occur
in temperate zones -- the American alligator, the Chinese alligator and
the broad-snouted caiman -- can tolerate occasional frost or freezing.
There are records of alligators surviving beneath ice as long as they
can continue to breathe. Of course, alligators normally become quiescent
in cold weather anyway. They dig deep burrows into the banks of rivers
and lakes and retire to them. They don't hibernate in the strict sense,
because they don't reduce their metabolism down close to zero. But
they're able to tolerate low temperature quite well.

long way to go to 30 feet
