FAQ:

 

1.  Penguins prey upon Krill, a Shrimp-like crustaceon

2.  Yellow-Eyed Penguin (Megadyptes Antipodes)

3.   Penguins are warm-blooded birds, (endotherm or homeotherm)

 

4.  "Penguins, for all their awkwardness on land, epitomize grace and power under water.

They fly underwater with powerful wing strokes, diving, careening, grabbing prey, and

avoiding a mixed bag of predators, including sharks, killer whales, sea lions, and leopard seals.

Penguins dart through the sea at speeds up to 15 miles per hour. Penguins of many species

also "porpoise," briefly shooting above, then below the surface in a rollercoaster-like motion." ~

Emperors of Spring

1. False; penguins EAT shrimp-like inverts. (http://www.mysticaquarium.org/index.cgi/582)

2. True, Megadyptes antipodes, the yellow-eye penguin. (http://en.wikipedia.org/wiki/Yellow-eyed_Penguin)

3. True; penguins, whales, and seals are all warm-blooded. (http://www.coolantarctica.com/Antarctica%20fact%20file/science/cold_penguins.htm)

4. True, Gentoo penguins can go up to 15 miles per hour. (http://www.pbs.org/wnet/nature/penguins/divers.html)

1. Penguins are prey upon shrimp -true
Penguins eat krill (a shrimplike crustacean in the family Euphausiidae), squids, and fishes. Various species of penguins have slightly different food preferences, which reduces competition among species.

When in the water, penguins may be eaten by leopard seals, fur seals, sea lions, sharks, or killer whales

On land, foxes, snakes, and introduced predators such as feral dogs, cats, and stoats (members of the weasel family) prey on eggs and chicks of some penguin species, including the yellow-eyed and Galapagos penguins (Sparks and Soper, 1987; Muller-Schwarze, 1984).

Antarctic and subantarctic eggs and chicks are susceptible to predatory birds such as antarctic skuas, sheathbills, and giant petrels (del Hoyo, et al., 1992). These predators may prey on chicks that have strayed from the protection of the creche or are sickly and too weak to defend themselves

2. Some penguins have yellow eyes - true  
The yellow-eyed penguin, as its name suggests, has yellow eyes and a stripe of pale yellow feathers extending over its dark head.

3. Penguins are warm blooded birds - true

These highly specialized marine birds are adapted to living at sea.

4. Penguins can travel up to 15 miles per hour. - false

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).

Swimming speeds generally are not well known (Kooyman, 1975). Earlier estimates of swimming speeds were taken from observations of penguins swimming alongside moving ships, a method that proved to be unreliable (Croxall and Davis, 1990). The fastest swimmers belong to the genus Aptenodytes. Emperors have been observed swimming 14.4 kph (8.9 mph), though they normally do not exceed 10.8 kph (6.7 mph). Both kings and chinstraps have been recorded at 8.6 kph (5.3 mph), Adélies at 7.9 kph (4.9 mph), and fairy penguins at 2.5 kph (1.6 mph) (del Hoyo, et al., 19921- Marchant, 1990).
