Purpose: To analyze and discuss the anatomy of the mink in order to compare to that of a human. Even though the mink’s anatomy will be a bit different some similarities could always be found.

Physical Characteristics
The general characteristics of minks is that they are mammals just like humans, which means that we both are born with hair, mammary glands for the females and different characteristics in our anatomy to those of birds and reptiles. Their scientific name is Mustela Vison. The mink has very long trunk, short legs and very large neck. The tail is thick and the feet are slightly webbed enabling them to swim better. In all the mink measures about 12-15 inches long and weight 1 ½ to 3 pounds. The fur is very dark almost black, on the chin the fur is white with a little white fur on its throat.
On the first stage of development the litter could be of 2 to 7 minks. They are born blind and deaf with little to no fur. They grow reddish hair when they are 2 weeks old. When they are finally 5 weeks old their eyes will star to open in the mean time the mothers have to feed them and protect them from predators.
On the second stage of development the minks are 10 weeks old they learn how to hunt. By fall, the minks leave their mother and start an independent life. They will mainly hunt snakes, rabbits, frogs, birds, mice and other small animals. Minks spend most of their time in the water. These creatures live on empty logs, or in a hole near the water.
On their third stage of development minks are ready to breed when they are about 10 weeks old, this happens January all the way to April. Males and females will mate with different minks. Generally female minks are in heat for a period of 3 weeks. After they have mated...

A Mink is a Carnivore found in many parts of the world. Two animals are branched out of the name “Mink”, there is the American Mink and the European Mink. The differences between these two animals include that the American Mink is larger in addition the difference can be seen in their skulls as the American Mink has a mandible that attaches to the rest of the skull differently than the European Mink allowing for greater range of motion ones it will bite. The American Mink is a semiaquatic mammal in the Mustelidae family. The mink has a long slender body and had long thick shaggy tail.
Minks and humans share various common characteristics because of their common roots in the animal kingdom. Both Human and Mink species are classified as Animalia Chordata Mammalia until they are separated by order, Humans being primates and Minks being in the order carnivora. It is because of their common roots that they have similar muscles types with similar functions, which help them survive and function throughout their individual habitats.
As of now, the Pygmy three-toed-sloth are critically endangered and weak law enforcement, deforestation, and poachers are to blame. The Pygmy three-toed sloths are described to have buff-colored faces with dark circles that surround the eye and go outwards to their temples. Like all sloths, they are always in doldrums, which can be very unbeneficial to them. They have clay-orange fur that covers their face and their hair is long and bushy. “Long hair hangs forward to the forehead, giving the impression of a hood” (Grzimek 161).
The American Mink (Mustela Vison) is a small, short haired animal belonging to the Mustelidae family. Much similar to a ferret in appearance the mink has short legs, short hair, a long tail, and a long sleek body with a long neck. It also has a small face, with small features, such as ears, a mouth, a nose and a pair of eyes. This report is consisted of a comprehensive commentary about the differences in the respiratory system between the mink and a human.

They have small heads and body’s with a long lumbar region and narrow chest. Saki’s are arboreal quadrupeds with their arms and legs equal in length. They have a long olecranon process to be able to lock their joints so that their limbs can hold equal weight. White-Faced Sakis have long prehensile tails and long phalanges on their hands and feet for better travel and balance in the trees. A Saki’s dental formula is 2.1.3.3 with triangular molars meaning they are insectivores. They are also known as "flying monkeys" because they are able to leap 30 feet between tree branches. I already knew they could leap so I was hoping to see that when I observed it, but it was resting when I was there. They are sexually dimorphic due to color. White-Faced Sakis are vulnerable to being

Sea Minks are commonly mistaken as the American Mink due to their close relation, and similarities. With the little information known about the extinct species they mainly rely on the relative to figure out knowledge such as their lifespan. It is thought the Neovison Macrodon had a lifespan of around 6-10 years. They were the largest of the Mink family, where they were, on average, 914 mm long. In addition, they were fatter, and had much blunter teeth than the American Mink. They had very coarse, deep red fur, and a slightly bushy tail. Females were called Sows, males are Boars, and children are Cubs. They had 5-10 cubs at once, and the cubs would stay with the mother for 13-14 weeks. Neovison Macrodon were nocturnal, solitary creatures, whose only known predators, were
The winter will last 8 to 10 months followed by the short and much less cold summer. During the summer some lower areas of the Tundra will defrost at which point most of the flora and fauna will start to creep out of hiding. The few summer months are used by many animals such as the polar bear, to mate and to prepare for the once again oncoming winter. During the winter months, most everything remains frozen. Many of the animals migrate south for the winter whereas some stay behind or even group together for ritual group suicide (lemmings).
...sheath encloses the penis of a mink and is held along the ventral wall of the abdomen. Male humans do not have this, and have much smaller penises relative to their body size. The percent of body length of the average mink and human penises are approximately 15 percent and 8 percent.
A mink is a good specimen to study the human anatomy because it is so closely related in internal features to that of a human being. Since these features are so closely related it provides a sort of “model” that can be used in order to better understand the anatomy of humans.
However, many of our questions still remain. The purpose of this paper is to discuss the physical aspect of gender differences in humans, otherwise known as sexual dimorphism, it’s evolutionary history in our species, and some behavioral and societal trends that are associated with it. To accomplish this, I will begin by outlining the anatomical structures that are commonly used in measuring sexual dimorphism in our species. After establishing these criteria, I will expand upon the evolutionary history of sexual dimorphism in humans beginning with the anthropoids in the Oligocene and ending with present day trends.
The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.
