Do penguins have knees?

Answer 1

Yes they do, they are just a bit higher up on the frame than you might think. They are hidden by the fluff and fat of the penguin.

Answer 2

penguins do not have knees

Answer 3

yes penguins have knees , i am a penguin so i know , by the way if anyone has a spare wooly hat send it to me at .....

Answer 4

Penguins are birds and they have the same leg structure as all other birds from hummingbirds to ostriches. If you consider that other birds have knees, then so do penguins.

Answer 5

Actually they do have joints equivalent to our knees - the difference is that these joints are much closer to the hip than on mammals.

Answer 6

I dont know, but i heard that if a plane flies over them they lean back to look, fall on their backs, cant get up and die. Thats sad really.

Penguins are superbly adapted to an aquatic life. Their wings have become flippers, useless for flight in the air. In the water, however, penguins are astonishingly agile. Within the smooth plumage a layer of air is preserved, ensuring buoyancy. The air layer also helps insulate the birds in cold waters. On land, penguins use their tails and wings to maintain balance for their upright stance.

All penguins are countershaded - that is, they have a white underside and a dark (mostly black) upperside. This is for camouflage. A predator looking up from below (such as an orca or a leopard seal) has difficulty distinguishing between a white penguin belly and the reflective water surface. The dark plumage on their backs camouflages them from above.

Diving penguins reach 6 to 12 km/h (3.7 to 7.5 mph), though there are reports of velocities of 27 km/h (17 mph) (which are more realistic in the case of startled flight). The small penguins do not usually dive deep; they catch their prey near the surface in dives that normally last only one or two minutes. Larger penguins can dive deep in case of need. Dives of the large Emperor Penguin have been recorded which reach a depth of 565 m (1870 ft) and last up to 22 minutes.

Penguins either waddle on their feet or slide on their bellies across the snow, a movement called "tobogganing", which conserves energy while moving quickly. They also jump with both feet together if they want to move more quickly or cross steep or rocky terrain.

Penguins have an average sense of hearing for birds (Wever et al 1969); this is used by parents and chicks to locate one another in crowded colonies (Jouventin et al 1999). Their eyes are adapted for underwater vision, and are their primary means of locating prey and avoiding predators; in air it has been suggested that they are nearsighted, although research has not supported this hypothesis (Sivak et al 1987).

Penguins have a thick layer of insulating feathers which are designed to keep them warm in water (heat loss in water is much greater than in air). The Emperor penguin (the largest penguin) has the largest body mass of all penguins, which further reduces relative surface area and heat loss. They also are able to control blood flow to their extremities, reducing the amount of blood which gets cold, but still keeping the extremities from freezing. In the extreme cold of the Antarctic winter, the females are at sea fishing for food leaving the males to brave the weather by themselves. They often huddle together to keep warm and rotate positions to make sure that each penguin gets a turn in the center of the heat pack.

Answer 8

not as such, the only animals that have knees are humans and elephants

Answer 9

Yes.They have a kind of "knees".

Answer 10

they have the same joints as other birds - just different lengths of bone

Answer 11

I don't know if they have knee caps but they sure have Ice caps
