Similarities Between Angler Fish And Polar Bears

The bear have evolved along time ago and now there is only eight species existing. They evolved from early canids during the late Oligocene and early Miocene, about 25 million years ago. The earliest ancestors where the Dormaalocyon Latouri. An intermediate ancestor was the short faced bear, very similar to the modern day bear. It lived through the pleistocene period. It grew to thirteen feet long and was a herbivore. The ancestors to the modern day bears lived in the same climate and ate the same things. The modern bear contrast from the ancestor because the ancestor was more skinny and was smaller, and it was more cat like. The eight species of bear that still exist. They are the Polar bear, Brown bear, American black bear, Asian

Anglefish and Goblin Sharks can be very diffrent, but if you dont know how to tell them apart it might just change your game. Howerver theese fish are very easy to tell apart, with one being a fish and the other being a shark. And the fact that Angle Fish are very colorful, wtih Goblin Sharks being a pale redish pink color. I am going to go into very specific facts about theese facinating creatures, so hold your horses!

      Anglerfish adapt to very extreme envirorments which they live in. Anglerfish can expand their stomachs so that they can eat two times their size. This  is really good because in the deep sea food is very scarce. So the fact that they can eat lager paportions is a very good adaption in their part. If they were not able to do that they would probally end up dieing.

did you know that angle fish have a lot verites of colors and gruops .

White bears require a variety of physical characteristics to survive in the harsh environment of the Arctic. Large, wide paws with bumps allow them to distribute weight and grip more efficiently. Water resistant fur with a luminescent quality keep the bear warm and dry. Additionally, Sharp and powerful teeth have the ability to penetrate hard flesh. These special features allow not only the ability to thrive in a difficult environment, but also are important for communicating with other species and another bear.

The polar bear, the largest land carnivore in North America, one of the largest animals in the world and a favorite at zoos worldwide, has, over the years, adapted to its harsh Arctic environment. The appropriately named ‘ursus maritimum’ or sea bear usually lives between 15 and 18 years in the wild and spends most of its life on ice. It is the most recent of the eight bear species. The first polar bear was a brown bear subspecies, with brown bear dimensions and brown bear teeth. The polar bear evolution was rapid due to the small population and extreme pressure to survive. Even today, the polar bear continues to evolve to better adapt to the harsh realities of Arctic life.

The latest survey conducted by the US Forest Service shows that as many as 97% of the animals of the Arctic could be affected as a result of the observed warming. The climate change may occur faster in the Arctic region. Scientists have developed computer models to predict changes in the environment and their impact on the 162 species of birds and 39 species of mammals in the Arctic.

After reading both of the stories I found that both the animals the Polar Bear and the Angler fish are Carnivores. They both have a harsh envirorment.Since they are both Carnivores thet dont have to good of a food supply, like if they live in a grassey green place since the only eat meat . They adapted to those harsh envirorments very well by,the anglerfish having to atract fish with the light on there head.Allthough the Polar Bear lives in -50 degrees.But the polar bear has black skin that absorbes the heat and 4 inches of blubber to go with that , the Polar Bear has to lay down in the snow to cool off. The Polar Bear has long strong legs and huge curved claws are especially adapted for striking and killing their prey. Now you know that theese

The habitats of fish greatly influence the way the fishes evolved. As presented in essay 1 by Dr. Stiassny mentions how the body of the fish are equip for the water. Water has a lot of density which causes drags when fishes swim. There shape bodies and cauda fin can help them move and communicate within their habitats. Fishes evolved from the way they ate. They use suction feeding as a way to quickly swallow their prey. The head of the fish has 30 movable parts with 50 muscles that fight the drag and helps with seductive feeding, which is demonstrated in the fish skull animation. In essay 2 doctor Dr. Stiassny mentions that fishes eyes are equipped for the water. There spherical shape has many layers. These layers have different “refractive

The female plays the biggest role in the relationship as she controls the food, and attracts the prey with her lure. This extreme case of sexual dysmorphism allows the female anglerfish to spawn whenever she needs to as she always has a mate available. The sperm travels through the mouth of a female and is fertilized to form a zygote. When the female is ready to produce her eggs, she lays them on a sheet made of jelly like substance two to three feet by 30 feet long. The sheet floats to the top of the ocean and when the eggs are ready they hatch and become larvae. Then the larvae eat plankton to sustain themselves, and eventually travel back to the bottom of the ocean as they grow older. The average female/male anglerfish has 46 chromosomes. Anglerfish are categorized by their genes, “They are characterized by the dorso-ventrally compressed morphology of the head and body, a wide and cavernous mouth, thin skin, an absence of scales and swimbladder, and a modified first dorsal fin ray (illicium) with a terminal esca, which serves as a lure.” (http://icesjms.oxfordjournals.org/content/65/7/1272.full) The variation in these genes can either be helpful or hurtful

There are not many creatures in the world that have the ability to not only survive thirty-two degrees below zero temperatures, but live in this climate as well. Among penguins and seals, polar bears are apart of the group of creatures that live everyday life in these freezing conditions. However, polar bears were not always able to do this. According to the Public Broadcast Service (PBS) website, polar bears evolved from brown bears through microevolution. Microevolution, by definition, is “small-scale evolution that occurs from one generation to the next” (Larsen p. A15). Due to the discovery of fossils, it is believed that brown bears evolved into polar bears between 70,000 to 100,000 years ago. This evolution can be seen by the change of fur color from brown to white to blend in while hunting for food and by the growth of a thicker, warmer coat to protect against the cold temperatures (PBS). This all occurred because of an event called the “ice age”. However, in the year 2316, an event called “global warming” will cause a much different evolution. Global warming is a phrase used to describe the ongoing, subtle rise in temperature of the earth and it’s oceans. Because of the small efforts being made to slow down global warming, nearly all of the ice caps in the ocean will most likely be melted by the year 2316. With polar bears only being able to survive by living on polar

     The anglerfish has to adapt to an environment that is so deep down into the ocean that you can not see any sunlight. The only light you may see is the bright esca which is used as a lure to attract predators. The esca is attached to what is almost like a fishing pole, called an illicium.The anglerfish can expand both their jaws and their stomachs.They special part of them helps them store food when food is scarce.

Polar bears are one of the most endangered species in the IUCN states this is due to Global warming which most of us are still ignorant about, It has a climatic impact on the Arctic by the rising temperature which results in melting the ice glacier and these glaciers are the homes of polar bears that have been disappearing and shrinking making it

Due to the effects of greenhouse gases, the sea ice that polar bears rely on for foraging and shelter is declining rapidly. Some populations of polar bears are forced to depend on their stored fat for energy during summer due to melting of the sea ice, which prevents them from hunting more efficiently. Being forced to rely on stored fat leads to a decline in energy intake, which leads to a decline in body mass. A decline in body mass correlates with slower reproductive rates and decreasing survival rates, which effects the growth and genetic diversity of the population. The increased amount of open water in between sea ice causes the polar bears to swim for greater lengths and therefore makes it more difficult for female polar bears to find proper dens for reproducing and protecting their offspring (Derocher and Stirling, 2012). The rate at which the sea ice declines is projected to accelerate over time (Derocher and Stirling, 2012), which means we will soon reach a year when severe malnutrition will lead to an irreversible decrease of polar bear populations (Aars et

The habit for the anglerfish needs to be dark and deep. The anglerfish body is made to handle high pressure and in order for the anglerfish to catch food it needs low light to lure prey in.
