Harp Seal Research Paper

Furthermore, the marine mammal science community, which has long maintained a neutral stance on the question of whether orcas are a suitable species for captive display, has finally recognized the need to engage. An informal panel discussion on captive orcas is scheduled at the 20th Biennial Conference on the Biology of Marine Mammals in December, the first time this topic will be openly addressed by the world's largest marine mammal science

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 problem with plastic ending up in the ocean is that marine life is being harmed by the presence of it. A study done on the harbor seals in the Netherlands found that more than 12% had plastic in the digestive system (California Coastal Commission). The list of affected species indicates that marine debris is affecting a significant number of species. It affects at least 267 species worldwide, including 86% of all sea turtle species, 44% of all seabird species, and 43% of all marine mammal species (Save our shores). The problem is underestimated because the marine life that ingests plastic or dies from entanglement often goes undiscovered due to the vastness of the ocean, as they either sink or are eaten by predators before they are discovered (Plastic Debris). The potential harm from ingestion of plastics is not restricted to seabirds. Plastic bags drifting on ocean currents resemble the prey of turtles. There is evidence that their survival is being hindered by plastic debris with young sea turtles being vulnerable (Ocean pollution). Over the past 20 years polychlorinated biphenyls (PCBs) have polluted marine food webs at an increasing rate, and are prevalent in seabirds. Though their adverse effects may not always be apparent, PCBs lead to reproductive disorders, increase the risk of disease and alter hormone levels. These chemicals have a detrimental effect on marine organisms even at very low levels and plastic pellets could be a route for PCBs into marine food

Orcinus orca is the scientific name for the massive marine mammal. Orcas are not rare, but have declining numbers in some areas (Martin.) Orcas are found from the Artic Ocean to the Antartic Ocean. (Britannica) They belong to the Delphinidae, or dolphin family, which is the largest

The Phocidae family consists of 29 existing species of earless seal that have been left from the initial 40. Out of this moderately sized group, we will be looking at the Hawaiian monk seal, Southern elephant seal, and the Crabeater seal.

As a Newfoundlander I strive to hold on to every bit of our culture and history we have left. Newfoundlanders have always been known for their hard work and dedication. We’ve found work in several areas, as the island we live on has given to us. The fishery, Pulp and Paper, and more recently oil and gas. Something we’ve always been part of is the Canadian Seal Hunt. Which takes place off the "Gulf" areas around the Magdalen Islands and Prince Edward Island. The main hunt on the so-called "front" usually begins in April off the east coast of Newfoundland. (FAQs: The Atlantic seal hunt, 2009) I am in support of the Canadian Seal Hunt, It’s something that has been a part of our history for years, and it helps many

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.

One specific hunt those organizations are trying to stop is the Canadian seal hunt or “Canadian seal slaughter” (Harpseals.org, n.d.) which is held between November 15th to May 15th every year in Canada. There are Thirteen species of seals that inhabit the waters of North America but two are mainly hunted, the harp seal and hooded seal, and more specifically baby harp seals between 3 weeks to 3 months, mainly for their pelt which sheds after that. Found Archaeological evidence reveals that the indigenous people of eastern Canada hunted seal for at least 4000 years. when the first Europeans arrived in the early 16th century, they began hunting seals, they began with hunting the walrus which lived along the Gulf of St Lawrence and the north shore

The article I read was about Hawaiian monk seals. Obviously the seals are found in Hawaii. The seals have six main islands in Hawaii where they populate: Kure Atoll, Midway Islands, Pearl and Hermes Reef, Lisianski Island, Laysan Island, and French Frigate Shoals. The Hawaiian monk seals are named the official state mammal of Hawaii. The Hawaiian monk seals have a diet that ranges from fish, squid, octopus, and lobster. The seals hunt mainly at night and during the day they lay on sandy beaches. The mating season for the seals is mainly from December until mid- August. When pup seals are born they are mainly three feet long and weigh about thirty-five pounds. The first month or two the seals stay with their mother so they are able to nurse.

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).

This creature is known as a harbor seal and was found on October 23rd, 1805 near the Columbia river, 100 miles away from the Pacific Ocean. and found in fresh water. They are also known to be found on the coast of California, they are often found laying on rocks on sandy beaches.

Harbor seals are active during the day and are usually found alone. The harbor seal groups don’t have social organizations or hierarchies. Harbor seals spread out to find food instead of traveling in a group. They usually stay close to land as that helps them from being eaten and they always seem to be aware of their surroundings. They are playful animals and often play by themselves or with seaweed or other objects.

The negative human impacts on harbor seals are devastating, and there are yet to be any major positive impacts. In the 1900s, fur traders would hunt harbor seal pups that were less than four weeks old for their fine coats, which were highly valued. This led to a decrease in the harbor seal population. Harbor seals were also hunted by salmon fishermen who saw the seals as competitors for the fish. After a while many harbor seal populations had to abandon traditional haul-out areas. This was sad for the seals, because the main diet of a harbor seal is fish.

The killings are inhumane. Sealers use clubs, sticks, guns, and spikes to murder seals, and it is not a quick death for the seals. Because most of the seals killed are pups, they have no way of escaping their death. Other seals can be mistaken for pups and be killed in the process.
