Harp Seal Research Paper

A Review of “The Devil and Deep Blue Sea” by Linda Pannozzo Introduction In her book The Devil and the Deep Blue Sea: An Investigation into the Scapegoating of Canada’s Grey Seal, Linda Pannozzo accomplishes few important things: she makes a compelling argument for the senseless killing of grey seal; she provides an analytic framework for the reasons of the decline of cod fish; and she provides a wealth of information on the politic behind scapegoating of Canada’s grey seal. Pannozzo presents The Devil and Deep Blue Sea in a clear and unbiased matter, but its presentation is by no mean elementary. Pannozzo’s book is meticulously researched, thus providing us with both quantitative and statistical account surrounding seal ways of life, their diet, history and other necessary aspects of marine life ecosystem. Book Summary

The leopard seal is one of six species of seals in the Antarctic. They can get up to 1230 pounds and fall anywhere between eight and twelve feet long. These large muscular animals have dark grey backs, and spots scattered among their light grey stomachs and throat. They get their name, “leopard seal”, from their impressively long sharp carnivore like teeth. Although their front teeth are sharp, their back teeth lock together to help them catch krill. Their appetite mainly consists of penguins, fish, squid, and krill, though they will prey on other seals. Although the leopard seal is considered the most ferocious seal in Antarctica, they will play with the penguins in a friendly manner. When they are not playing with the penguin they will grab

Not only will climate affect the ecosystems but will also affect the animals. Climate change affects habitats for thousands of species. Animals that are affected by this would either have to adapt to the new environment or roam other places. Climate change can change life cycles for animals and

The most important thing to a harbor seals survival is its habitat, which determines shelter, adaptations, evolution, and the type of food available. Harbor seals live in shallow waters of coastal areas, sandy beaches, rocky islands, mudflats, and bays.

The traits for a bottlenose dolphin and a harp seal are similar and different,but mostly different.The are both grey.Even though they both have the same color a bottlenose dolphin weighs much more than a harp seal.A bottlenose dolphin’s length is eight and a half feet and a harp seals’s is five and two feet to six and two feet.Bottlenose dolphins’ life expectancy is up to twenty to fifty years,which is much greater than a harp seals’ life expectancy,which is up to thirty five years.

Every year in the Gulf of Saint Lawrence and the Northern Atlantic Ocean, three Canadian seal populations are opened for commercial hunting. Since the 1750s, hooded seals, grey seals and iconic harp seals have been hunted for their valuable pelts and omega-3 rich oil. After being nearly hunted to extinction in the 1800s and a period of extensive anti-hunt activism in the 1960s and 70s, the hunt has become strictly regulated. Now, activism has forced the Atlantic Seal Hunt to support and maintain standards of sustainable resource harvesting and humaneness, and this hunt now has the potential to be a role model in these areas for other similar hunts worldwide.

The Hawaiian Monk seal is a greatly endangered marine species. These adorable creatures are being used for human goods such as their skin, meat, and oils. Not only this, but predators like Sharks and poisoning have also killed off the breed. Today in 2017, only about 1,100-1,400 are fighting for their lives. Since these beautiful creature, live on a touristy island, it is common for humans to be one of the biggest threats. Humans can throw litter and plastic into the water just to watch these animals suffer. Their own kind have also been a rising cause of these animals decreasing population by the males killing the females in group attacking called “mobbing”. These creatures are supposed to live anywhere

Baby harp seals are disappearing in population because of the climate change going on near their habitat. These pups are constantly drowning and being crushed by melting ice every day. If this keeps occurring, they will quickly stop breeding and eventually become extinct. Although they are not endangered, baby harp seals are passing by the minute. If you think this is unacceptable and want them to be saved: choose energy efficient appliances when making new purchases, replace a regular incandescent light bulb with a compact fluorescent light bulb, use a clothesline instead of a dryer when possible, cover your pots when cooking, and speak up to the public about how others can do these things too!

The population decline in monk seals is due to several different factors with the biggest reason due to the low pup and juvenile survival rates (Curtice et al, 2011). At the Kure Atoll on the Northwestern Hawaiian Islands, 32 pups were observed in 1964 and 30 pups were observed in 1965. Of these pups born, all but one died or disappeared within 60 days after birth. This was also seen in the 1970’s at Green Island and Kure Atoll, where a mean population of 17 and 14 seals, respectively, was counted on these beaches, with a birth total of 10 showing a population decline of 70% (Gilmartin et al, 2011). The juvenile survival rate is still seen today with one in five monk seals surviving to the reproductive age, with one year old seals having the highest mortality rates (Norris et al, 2011).

They weigh about 300 pounds and males quiet larger than females, They come in various colors example, gray, white, yellow and many more. Harbor seals eat fish, and their blubber helps to keep them warm. Their skin is made for them to swim vividly in the water.

Warmer winters leave seals without protective ice dens. This exposure to the elements increases infant mortality and leaves adults unprotected from fisherman. Fishermen use nets to trap the seals, which also end up littering the oceans. An average of 60,000 seals were killed each year between 1984 and 1994. Most of the pelts are first purchased by processors in Newfoundland. The seals are also facing pollution, which causes habitat loss. Predators of seals are the Orca, Killer Whale, Great White Shark, and Polar Bears. Global warming is another concern for seals. As the polar ice caps melts, the seals find more predators in their natural habitat. Which means they are at risk of being eaten as well as having to share their food and other supplies. Seals have to eat more to gain blubber and keep themselves warm. Seals that live in colder regions are heavier in

Seals hunt for their food in the sea. Their whiskers aid them in detecting the route of fish. Because their stomach prints are found at the bottom of the sea, seals are considered bottom feeders. Strategically, they use their tusks to dig immense furrows in search for clams. Seals feast on fish, shrimp, mussels, and clams. In the Antarctic, the elephant seal is noted for fiercely hunting down sharks. Furthermore, seals utilize their tusks for tilling the seafloor while scavenging for clams. The sea is a seals source of

The Caribbean monk seal is a type of seal that went extinct and was last reported to be seen in the year of 1952, but they were endangered since 1700s. In this essay, I will go over about different reasons and causes for this animal to go extinct; including two reversed hypotheses. You will also learn about their previous habitats and ecosystems. Over all, humans made a great impact in the extinction of the Caribbean monk seals.

The world we live in is so vast and exciting. Seventy percent of our world is liquid water we call the ocean. In the ocean there are many creatures that each are unique in their own way. However, it is possible that in our lifetime, many marine organisms will become endangered or possibly extinct. The loss of these mejestic marine creatures will be caused mainly because of human advancements in which fossil fuels are used to produce energy. Biodiversity is greatly affected by this increase in acidity. As the ocean acidifies, multiple social and economic issues arise. As humans, we rely on the ocean for almost everything. Much of our food, clothing, cleaning products and cosmetics come from the ocean. With the loss of
