penguins in cold places?

Question

penguins live in very cold places. Why doesn't their blood freeze?

Answer 1

Penguins have great protection from the freezing conditions, which by the way they happily endure. Afterall, they know no different. Depending on the species of penguin, some have a very fine plumage which traps a layer of air. This protects them from the cold, other species have a very thick layer of skin almost like rubber. Great protection !

Answer 2

For the same reason our blood doesn't freeze if we go out in very cold weather - they are warm-blooded creatures that generate heat from the food they eat. Penguins have a hefty fat layer to insulate their bodies and warm their blood so that their extremities don't freeze. They are able to hold the heat they generate very well - certainly better than we do. Their rich diet of fish is very important to enable them to do this.

Answer 3

There are penguins almost on the Equator, in the Galapagos islands. Lots around Sydney - there is a colony of little penguins in Sydney Harbour.

Penguins are warm blooded, like us, so they develop heat by metabolising food. They have an internal heat source, so their blood does not freeze.

Answer 4

One, they are warm blooded so they generate internal body heat, Two, the down and feather layers they have provide superb insulation against the cold, not taking into account the fat they carry which also provides insulation. I do believe their blood also has a biological anti freeze element in it as well, and no I'm not joking.

Answer 5

For two reasons, first is that they produce heat (like humans do) and they have a fat layer that keeps their heat inside. (nearly all polar creatures have fat or fur to keep warm).

Secondly, they never come into contact with something that is both very cold and conducts heat well. Ice and air in the arctic are cold, but conduct hear poorly, water is relatively warm (if it were really cold it would be ice) and conducts very well.

Answer 6

nicely, there isn't something keeping them there, ya understand. as a count of certainty I discovered after repeated viewings of "chuffed feet" mutually as minding a team of small Heathen toddlers that curiously some penguins holiday in Scotland. i'm able to think of of no different clarification for the accessory one in all them had.

Answer 7

their layers of fat and waterproof feathers insulate them from the cold. Their anatomy is such that their feet partially freeze, so as to avoid them freezing completely.

Answer 8

A good question. Same could be applied to anything Polar I guess.
