Brown Fur Seal

see if the water was in a suitable condition for the animals to live in. after learning about how to maintain a temperate aquarium we looked into local marine issues such as seals in the Coorong and local sharks. 2. (1) What animal did you choose to research? Why did you choose this animal? I chose the Australian fur seal as is being one of the suggested animals for the project and they are one of my favourite animals (2) What presentation format did you choose for your Final Presentation? Why

​1 Reproducing is the only method of insuring genetic DNA of organisms is passed on to the next generation. There are two types of reproduction, asexual and sexual. From the family Otariidea, Sea lions use sexual reproduction meaning they require a mate to produce offspring. There are 6 living sea lion species in the world. The Japanese Sea Lion, Zalophus japonicas, became extinct within the 1970’s. The Steller sea lion has the largest sea lion population and lives in the Northern Pacific. The California

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. Today’s

It is believed the Polar bears that walk the earth today, had descended from brown bears. This occurred through geographical isolation due to glacial drift in an area close to Siberia. They had undergone a rapid evolution, with changes that enabled them to adapt and survive in an Arctic habitat. This involves a change in the shape of their body, skull and ears, the colour of their skin and fur, and the digestion of seal fat. Skull & Ear Shape The Polar bear has developed a weaker cranial morphology

came from the brown bears ancestors. Most experts think that polar bears are the longest bears. Males measure over 10 feet long, when standing on their hind legs, other bear not so much. Brown bears and polar bear are the largest and are both land carnivores. Polar bears are one of the worlds largest world predictors. 2.) Polar bears don’t hibernate! Polar bears don’t hibernate, expect if it is a pregnant female that hibernates over-winter in dens. Unlike other bears like brown, black, grizzle

SKIN AND FUR Cut off and forced to adapt Population of Bears went away from the rest of the species. Because of rivalry for food?? Imprisoned by glaciers and became separated in Arctic. Lots died from the unforgiving/ harsh environment, but those with evolutionary advantage( IE ideal fur colour) stayed alive and reproduced ‘cause paler bears had better advantage owing to the white hue of the habitat, whereas darker fur bears had harder times blending into the frequently icy habitat while hunting

hundreds of thousands of years. The analysis of the DNA of a distinct population of brown bears inhabiting Alaska’s ABC Islands (Admiralty, Baranof and Chichagof) approximately 1,450km south of the nearby polar bear habitat, revealed that the ABC bears were even more closely linked to polar bears genetically than they were to other brown bears. Polar bears are believed to have diverged from a population of brown bears that became isolated during a period of glaciation in the Pleistocene. (DeMaster

active all year long. They are also called Snow foxes or White foxes because they live in the snow and their fur is white. They have very thick fur which keeps them warm. Their paws are covered in thick fur, too. This lets them walk on ice and snow. In the winter their fur is white and sometimes blue-gray. Their coat changes color with the seasons. In the summer their fur is brown. This helps them blend in with the rocks and trees and plants. Their ears are front-facing. This helps them

Although polar bears are known for their white fur, they actually have black skin under this translucent, hollow hair. Their translucent hair is able to reflect light, while the hollowness works as an insulation and helps with buoyancy in water. Their fur covers a thick layer of fat that aids warmth. Polar bears also have furry hind feet that give traction and warmth to bears as they move across the

Type of Bears Are you interested in bears? Who wouldn’t be. There are three different kinds of bears. The three types of bears are, black bears, brown bears, and polar bears. Every one of these types of bears is different in some kind of way. BLACK BEARS Most black bears are found in North America. It is estimated that there are at least 60,000 black bears found in North America. Black Bears are omnivorous, they eat all sorts of different kinds of food, such as plants, fruits, nuts, insects
