Do penguins have fur or feathers, fins or wings?
594157
Penguins are birds (Aves) in that they have feathers, lay eggs and have forelimbs modified as wings (but in this case used for swimming). They also share all the other characteristics of birds, being warm-blooded (around 40 deg C) and having a reduced reproductive system (one functional ovary or testis).\nLike all other birds, penguins have feathers. Penguin feathers are short, overlapping and densely packed. The outer part of the feather is waterproof while the inner down section traps an insulating layer of air, keeping the penguin warm in the sometimes freezing water. Unlike those of flying birds, the feathers on a penguin wing are very short.

The Following Text Is Taken From Wikipedia..:\n\n"There are either 17 or 18 known species worldwide, depending on whether the two Eudyptula species are counted as distinct. Although all penguin species are native to the southern hemisphere, they are not, contrary to popular belief, found only in cold climates, such as Antarctica. In fact, only a few species of penguin actually live so far south. Three species live in the tropics; one lives as far north as the Galápagos Islands and will occasionally cross the equator while feeding.\n\nThe largest species is the Emperor Penguin (Aptenodytes forsteri): adults average about 1.1 meters (3 ft 7 in) tall and weigh 35 kilograms (75 lb) or more. The smallest penguin species is the Little Blue Penguin (also known as the Fairy Penguin), which stands around 40 cm tall (16 in) and weighs 1 kilogram (2.2 lb). Generally larger penguins retain heat better, and thus inhabit colder regions, while smaller penguins are found in temperate or even tropical climates. The rarest type of penguin is the yellow-eyed penguin (megadyptes antipodes) and is probably the most ancient of all living penguins. adults average about 65cm tall and the adults average weight is 5-6 kilograms\n\nMost penguins feed on krill, fish, squid, and other forms of sealife caught while swimming underwater. They spend half of their life on land and half in the oceans.\n\nDue to the gender ratio, penguins are one of the few species on the planet whose females fight over single males during mating season, due to the comparatively low number of male penguins.\n\nOne of the most baffling forms of behavior of the penguin comes when a mother loses her chick, either due to its being unable to endure its first storm, or due to other reasons such as predators. When a mother loses its chick, they have been known to actually attempt to steal another mother's living chick- presumably in order to deal with the grief of the loss. This behavior has amazed scientists, as it is an emotional outburst opposed to an instinctual behavior; something many animals do not exhibit when losing their young. Many have used this as prime evidence for decades that many animals have near human-like emotions and feelings, often for the sake of animal rights. Interestingly, the other females in the penguin groups dislike this behavior and will help the defending mother keep her chick. Another fact about penguins is that they are one of the few species of birds that seem to have no fear of people. In fact, they have been known to approach groups of explorers without the slightest hesitation."\n\nFor More, See The Link(s) Below..

Primary flight feathers are those supported by the bird's hand, and they provide mainly thrust. \nSecondary feathers are supported by the ulna (our cubitus), are situated in the forearm and provide lift. Thus, good gliding birds have relatively long forearms and well developed secondary flight feathers, while good "speed" flyers, and especially those with acrobatic flight such as swifts or hummingbirds, have relatively more developed hands and primary feathers.\n\nPrimaries and secondaries may differ in shape (primaries are more asymmetric, and sometimes longer) but that depends very much on the shape of the wing.

Yes, I agree.  So are the Penguins.  \nOilers rock!    lol....

Its their feathers keeping them warm, but havent you been wondering about something else?\n\nWhy is it that ducks feet dont freeze to the ice?? Huh??? :p

Penguins have extremely tough feet to start with for walking across rocky beaches. They also have what is known as a counter current heat exchange system. The feet dont have any muscles in them, or very few, but they do have a lot of tendons so they can still move them. Not having the muscles there mean that they feet dont have to stay as warm as the rest of the body, so they will be cooler than the rest of the penguin. The counter current system means that warm blood in the veins coming from the body to the feet passes really close to the vessels carrying colder blood from the feet. As they pass close to each other, the heat from the warm blood gets transferred to the cooler blood warming that blood and cooling the warm blood so not that much heat is lost thorugh the feet, even though they are touching ice and snow all the time. This also means that the colder blood doesnt shock the body and with less of a gradient betweent he feet and the environment, the heat is lost slower than if the difference between the foot temp and the ice was greater. All of this keeps the feet cooler but not freezing. What also helps is the tough scaley feet that i mentioned earlier as well as the ability to cover the feet with essentially belly fat rolls when not walking and penguins reduce the amount of surface area in contact with the cold area by standing on their toes or rolling back onto their heels. All these things help penguins maintain a much warmer body temperature than their surroundings. \nAs a side note, the feet are also the penguins way of staying cool. Since they rest of the body is so well insulated, they can actually overheat and the feet is where the excess heat is lost, also though a counter current system.

Not without human involvement.\n\nThere was the great auk, a species of flightless bird which occupies much the same ecological niche in northern Atlantic, which was the original bearer of the name "penguin". Its smaller cousins, the auks, retain the ability to fly.

It's a mixture of the above answers: the penguin does control the flow of blood to the feet, by varying the diameter of the vessels carrying blood into the feet. When it is cold they reduce the flow (this means less blood to heat up when on its way back into the body). The second method of control is by way of the countercurrent heat exchangers at the top of the penguin's legs. The blood vessels break into many smaller vessels that are very close to similar small vessels coming back up into the body. All the heat flows from the warm blood into the cold, meaning little warmth is carried down into the feet and lost to the environment, keeping the heat in the penguin! The feet are a degree or two above freezing, which is just above what they would get frostbite at, but still minimises heat loss.

Penguins have a special patch on their body that secretes oil. They use this oil to waterproof themselves so that they are less effected by the chilly waters.\nEmperor Penguins have developed a system that allows all of them to stay warm. They all huddle in one big group, which conserves their body temp. They cycle through which penguin gets to be on the inside and which on has to be on the outside. \nPenguins also have thick layers of fat that insulate them.

They could. There were fish that evolved from swimming to walking. There is a fish called the flying fish that can jumpfrom the water and glide through the air for a ways to escape predators. Follow the link to see a picture, its fins look very similar to wings.\n\n\nhttp://oceanlink.island.net/oinfo/biodiversity/flyingfish/flyingfish.html

Absolutely not.  They are warm-blooded creatures capable of maintaining an internal body temperature.  If birds were cold-blooded, you can bet that penguins and non-migratory birds would be in deep trouble when exposed to low temperatures!

Sheep is a good word. But I prefer to call them penguins, they waddle (must be all those pot lucks they have at church).

Yes. Penguins appear to have very short legs and no knees because only the lower leg is externally visible. Their knees and upper legs are feather covered, hiding them from view. This also means that penguins never get cold knees\nSee\nhttp://www.penguin.net.nz/faq/faq.html

1. Warm blooded\n2. Give birth to live young.\n3. Have mammary glands and nurse their young\n4. Have hair (yes, ehales and dolphins in utero have hair and some remains shortly after birth)\n5. Breath with lungs (while not a mammal exclusive trait it separates them from fish)\n\nOther marine mammals include seals, sea lions, manattees and sea otters.
