do penguins lay eggs and do penguins have knees?

Answer 1

Yes Penguins lay eggs

1. Eggs may be white to bluish or greenish. The shape varies among species. In Humboldts and Adélies the egg is more or less round. In emperors and kings the egg is rather pear-shaped, with one end tapering almost to a point.

2. Egg size and weight varies with species. From the records of SeaWorld's successful penguin breeding programs, emperor penguin eggs measure 11. 1 to 12.7 cm (4.4-5 in.) long and weigh 345 to 515 g (1 2.1-18 oz.), and Adélie penguin eggs measure 5.5 to 8.6 cm (2.2-3.4 in.) and weigh 61 to 153.5 g (2.1-5.4 oz.).

3. A nest of eggs is called a clutch, and with the exception of emperor and king penguins, clutches usually contain two eggs. (Emperor and king penguins lay a single egg. ) A clutch with more than one egg presents a better chance of at least one chick surviving (del Hoyo, et al., 1992).

Penguins dont have knees.

1. Penguin legs are short and strong. Feet are webbed, with visible claws. The legs are set far back on the body to aid in streamlining and steering while swimming. This placement also causes penguins to stand vertically and walk upright (Marchant, 1990).

2. Penguins walk with short steps or hops, sometimes using their bills or tails to assist themselves on steep climbs (del Hoyo, et al., 1992). The maximum walking speed for Adélie penguins is 3.9 kph (2.4 mph). Emperors and kings walk slowly and do not hop. The maximum speed for emperors is 2.8 kph (1.7 mph). Some species, like the rockhopper, jump from rock to rock (Miller-Schwarze, 1984; del Hoyo, et al., 1992).

3. Antarctic species can move much faster over ice by "tobogganing" on their bellies, using their flippers and feet to help them move along (Simpson, 1976).

Answer 2

yes and yes
"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! " --http://www.penguin.net.nz/faq/faq.html

Do penguins reproduce by laying eggs?
"Pretty much in the same way that all other birds reproduce - the female is mounted by the male and sperm passed from cloaca to cloaca. The egg is fertilized at ovulation, but yolk development starts 14-17 days before this. After that the alumen (white) and shell are added and the egg moves down the oviduct. In all it takes around 23 days. The second egg is laid after 3-4 days." --http://www.penguin.net.nz/faq/faq4.html

Answer 3

Penguins do indeed lay eggs; they generally incubate them by putting them on top of their feet, and keeping them next to a small area of the body that does not have feathers. As to knees - I would imagine their basic structure is the same (internally) as most other birds, with "knees" that bend opposite to those of human beings.

Answer 4

Penguins do lay eggs which are hatched by both parents alternately. Judging from pictures, I would say that Penguins do have knees but cannot confirm.

Answer 5

yes they lay eggs and yes they have knees you can see them when the penguins jump out of the water

Answer 6

Yes, penguins lay eggs and the male nest them under their large bellies between their feet.

If you want to know all about penquins, I would suggest you see March of the Penquins. It is a most wonderful informative movie. Morgan Freeman is the spokesperson for this documentary which is very entertaining and delightful. You will have a new respect for penquins.
