Heat Conservation Advantages for Penguins When Huddling
Aim and Introduction
My aim is to find out the heat conservation advantages are for
penguins are when huddling. I will be huddling boiling tubes (to
represent the penguins) containing hot water (to represent the
penguins' blood) and measuring the temperature over a period of time.
I also had a control boiling tube on its own to see how the
temperature is affected by not huddling.

To keep themselves warm penguins use blubber as well as stiff tightly packed feathers (up to 70 per sq in). These feathers also overlap and provide waterproofing. They coat these feathers with oil from a special gland to make them impermeable to water. New ones grow underneath, but penguins grow new feathers under the old ones and then the old ones are shed all at once. Because Penguins are flightless this complete malting is no hazard to them
There are 18 different types of Penguins but they all have certain
things in common. All penguins have the well-known tux coloration.
Some are white and black and some are white and blue simultaneously.
Colour in penguins is rare, being limited to red or yellow irises of
the eye in some species, red beaks or feet in a few species, yellow
brow tufts in the three species of Eudyptes and orange and yellow on
the head, neck, and breast in the two species of Aptenodytes.
Penguins range from about 35 centimetres (14 inches) in height and approximately one kilogram (about two pounds) in weight, in the little blue, or fairy, penguin (Eudyptula minor), to 115 centimetres (45 inches) and 25 to 40 kilograms (55 to 90 pounds) in the emperor penguin ( Aptenodytes forsteri )
The total populations of some species, such as the emperor penguin, are estimated in hundreds of thousands, but those of most species of smaller penguins certainly run to several million. The largest breeding colonies are on the islands between 50 [IMAGE] south latitude and Antarctica . These immense colonies, some of which contain hundreds of thousands of individuals, represent a large potential food resource, but the economic importance of penguins is negligible.
The body of the average Eastern Chipmunk is about 8 to 10 inches long, the weigh about 2 ½ to 4 ounces. The ears are rounded with ears that stick straight up. It has short legs, the hind legs each have five claws, the front legs have four, and a long thumb like extension. They also have a furry flat tail.
For this evolution project, I choose to research Penguins. The classification for this animal is as follows: K Neornithes, P Palaeognathae, C Neognathae, O Pelecaniformes, F Procellariformes, G Graviidae, S Spheniscidae. The first fossil penguin that was found, is today being held in the British Museum of Natural History. It was reportedly found by an anonymous Maori in New Zealand in 1859 and was named Palaeeudyptes Antarcticus despite the fact that the species was located far away from Antarctica. Since that discovery many more fossils were found and were dated back to the Miocene era and three others from the Pliocene era. Several fossils were dated to the Late Pliocene era and others from the Recent era. The earliest avian fossil found in the southern hemisphere is said to have existed in the Eocene age about 38-54 million years ago. There is evidence that at least three of the modern penguins (Aptenodytes, Spheniscus and Pygoscelis) went extinct within the last 4-5 million years. The remainder of the penguins are from 5-40 million years ago, dating back to the time currently recorded, when penguins evolved from other modern birds. Research suggests that the tallest of these penguins were about 6 feet tall. Penguins did originate from an ancestor that flew some 40 million years ago. The common ancestor is assumed to have been somewhat similar to a modern-day diving petrel or auk in appearance and behavior.
Puffins live at sea while not mating or raising young. They glide across the water, swim on the surface of the ocean, and dive to depths of nearly 200 feet to get their food. Puffins commonly spend their entire winter at sea. Young puffins will spend two to three years out at sea before returning to land to mate.

Thanks to evolution, Penguins have evolved into a group of aquatic, fightless birds, that are highly adapted to life in the ocean. This not only makes them one of the divergent and strange species of birds, but also has allowed them to become such a sucessful species. Penguins are mostly located in the Southern hemisphere ranging anywhere from the Galapogos to the Antartic. Throughout their lives, Penguins spend around half their time in the ocean doing things such as catching food and the other half on land raising their young. Their distinct tuxedo-like apperience called countershading camoflages their bodies, protecting them from predators above and below. Through out the “stepping stones”, the penguins grew to have a dense bone containing
After watching March of the Penguins I was browsing the internet while I was trying to figure out which direction to take the essay in, because there were too many possibilities for the topic. Soon I found myself watching Monty Python, when the perfect sketch to start this paper on comes on. A newspaper reporter comes on saying "Penguins, yes penguins what relevance do penguins have with the furtherance of medical science? Well strangely enough quite a lot" He moves into a joke about research not being accidental. Then he picks up of the penguins "Nevertheless scientists believe that these penguins, these comic flightless web-footed little b@$#ards are un-wittingly helping man to fathom the uncharted depths of the human mind." The news cast flips to the scientist who introduces himself then states "...having been working on the theory postulated by the late Dr. Kramer that the penguin in intrinsically more intelligent than the human being." From there a multitude of science spoofs lead to the confirmation of this theory of penguins being smarter, even though it is clearly pointed out that the penguin's brain is smaller than of a human being. This causes the penguins to rise up and take over the roles of humans. After careful consideration I decided to discuss this clip as there really is no better way to introduce how animals are used in film as entertainment. Whether it is a crazy Monty Python sketch or the heartwarming love story that is March of the Penguins both were created for many reasons, but the most influential was the desire to earn money. For now just keep Monty Python on the back burner it will have significance later, lets shift to dealing with the questions being posed about March of the Penguins. How did March o...
The science and anatomy of the platypus is one of the many ways it is unique. This three to five pound creature can be anywhere from fifteen to twenty-two inches in length. One way to think about its size
The large ground finches have a higher curve while the medium ground finches have a smaller head and a tiny beak. The place in which the finches live is what changes their appearances and also the weather helps decide the appearance of these finches.

The polar bear is one the largest members of the bear family. Males Polar Bears stand from eight to 11 feet tall and generally weigh from 500 to 1,000 pounds, but can weigh as much as 1,400 pounds. Female bears generally stand eight feet tall and weigh 400 to 600 pounds, except some, which can reach 700 pounds. The reason the polar bear weighs so much is that is stores about a four-inch layer of fat to keep it warm.
The Arctic fox is a medium-sized animal. It usually weighs between six and seventeen pounds . Its long bushy tail is usually twelve inches long. The rest of its body is typically a few inches shorter, or the same length, as its tail. Sometimes male Arctic foxes are longer and heavier than female Arctic foxes, but not always.
