Pinniped

Both when dependent, or still nursing and independent of their mothers, the juveniles emitted stronger responses to the calls of their mother than to the calls of other unrelated females. This evidence is further support that numerous Pinnipeds posses the ability to recognize related individuals, especially their mothers, up to two years after the pup has become independent from its mother and possibly well into adulthood. As stated previously, Insley (2000), showed that 4-year-old females…

Pox virus is a double DNA virus that is best characterized by lesions that appear on the skin. The virus is identified using an electron microscope to find the brick shaped virions (King 2012). The use of Polymerase Chain Reaction (PCR) can identify which subfamily and genus the strand of pox virus is classified under. The family Poxviridae can be split into two subfamilies Chordopoxvirinae (vertebrate pox virus) and Entomopoxvirinae (insect pox virus) (Bracht et al 2005, King 2012). The…

species is still thriving. The red panda is very unique in the way of their family. Their name references that they are a close relative to the panda but, science has proven that wrong. Red pandas are more closely related to, Pinnipeds, raccoons, skunks and mustelids. Pinnipeds include, seal and walrus and mustelids include, weasels, otter, martens and…

Cartilaginous fishes provide a notable example of successful evolutionary perseverance with a fossil record extending to at least the Lower Devonian over 400 million years ago (8). Carcharodon carcharias, also known as White Pointer, White Death, or more commonly, White Shark, is one of the greatest predators in the world among marine life. They are usually found in tropical areas but research has been conducted on these sharks from the Northwest Atlantic to Southern Africa to North East near…

Around the world, a theory of evolution by natural selection is supported by many scientists. Charles Darwin was one of the scientists who have create the most famous theory of natural selection. The theory of evolution by natural selection says that animals change in each generation because of natural selection. Natural selection is when animals can survive more easily because of their features, such as, colour, ear shape, and digestion. Over time, the animals that can survive are the ones that…

The anatomy and physiology behind Odobenus rosmarus rosmarus and Odobenus rosmarus divergens adaptations Korina M. Ramirez November 5, 2015 The only extant lineage of pinnipeds under the genus Odobenus are the walruses. This genus includes two widely accepted species Odobenus rosmarus rosmarus, the Atlantic walrus, and Odobenus rosmarus divergens, the Pacific walrus. The environment these animals live in are harsh and require quite the adaptations in order to adjust due to many issues…

The killer whale or orca is another name for species Orcinus orca. It is a toothed whale that belongs to the family Delphinidae in the order Cetacea.. They are found globally in all oceans. In fact, after man they are the most widespread mammal in the world. Killer whales live in pods. The structure of the pods are usually matrilineal. This means that the offspring wait with their mother throughout life.The individuals in a matrilineal group travel closely together. The killer whale worldwide…

While near pinniped rookeries in autumn and winter, sharks avoid the surface and use water to 50 meters in depth which is consistent with a silhouette-based hunting strategy. White sharks also exhibit a broad depth distribution offshore and remain there for the spring and summer (4). White Sharks typically spend their day in temperatures between 15C to 24C (59F to 75F). However, as they begin to hunt their prey, they dive down deep into the ocean and slowly rise as they look for food. Sharks…
