The monk seals are a rare tropical animal that lives on the Caribbean and the Hawaiian Islands. Monk seals live in warm waters and spend about two-thirds of their time at sea. However, they also spend time on land as they breed and carry-out their “pups.” Coral reefs provide the seal as a great habitat for them to dive, swim, and for food such as fish. It may seem that monk seals spend most of their time at sea, but they also love to rest on shore on the beaches.
Warmer temperatures are rapidly melting seasonal ice cover in shallow continental shelf, which walruses need in order for them and their pups to rest. Additionally, mothers take advantage of the time their calves are resting to dive and feed off of bottom-dwelling animals such as crabs; inability to adapt to shallow waters with no ice cover could result in a significant population decline (“Walrus Calves Stranded”,
One of the main reasons polar bears are going extinct is because they aren’t getting the right amount of food they need to survive. Seals, the main food source for the polar bears, are animals that depend largely on the algae that grows on the ice of the Arctic. With the ice content slowly depleting, there isn’t enough seals to sustain the polar bear population. One of the
The Hawaiian monk seal, or Monachus schauinslandi, was one of the original species to be placed under the Endangered Species Act that was enacted in 1973. As of 2010, the population of the monk seal is approximately 1,100, with an annual decrease of approximately 4.5%. The Hawaiian monk seal is primarily found on the Northwestern Hawaiian Islands that are made up of coral reef atolls, seamounts, banks, and shoals. This is due to the fact that the monk seals primarily forage on the barrier reefs of the atolls, on submerged reefs, and on banks further from the atolls (Curtice et al, 2011). The monk seals primarily like to look for food on the surface of the ocean floor and will search for food in depths up to 500 meters. (National Marine Fisheries
”Many say that the seals may be on their way to extinction even though studies show that is nearly impossible at this point in time. Personally I believe that seal hunting is good for multiple reasons in which I will explain in this essay. The first reason that I believe that seal hunting is good for not only the environment but the species itself is that seals are becoming over populated. When people hunt not only seals but other
The Hawaiian Monk Seal (Neomonachus schauislandi) is a primitive, non-migratory phocid endemic to the islands of Hawaii (National Marine Fisheries Service, 2007). These primarily aquatic pinnipeds spend two-thirds of their lives in the water but require some land, often sandy beaches, to haul-out for reproduction and rest (NMFS, 2007). Monk seals have a polygynous mating structure but precise mating behavior and dominance establishment is unknown because they are aquatic processes not often observed (Jefferson et al., 1993). Females begin giving birth around age five to nine with each female producing a single pup every year (Johanos et al., 1994). After giving birth, females will stay and nurse their pups while fasting and energetically supporting
They use the ice to rest on while hunting for seals, but since there is less ice it’s causing the polar bears to drown from exhaustion. Walruses can eat up to 200 pounds of clams each day. Clams are usually found near the continental shelf but with ice caps melting it is getting harder for walruses to find
Finally, changes in environmental conditions are also responsible for the collapse of the East Coast Fishery. Water temperatures have dropped and ocean salinity levels have changed, causing fish to change their migratory routes, and avoid areas that are changing. People have suggested that the increase in the seal population has reduced the amount of fish because greater quantities of seals eat greater quantities of fish. In conclusion, a number of theories such as, overfishing, destructive fishing practices, and changes in natural conditions explain why the East Coast Fishery has
Their coloring provides a camouflage to the ocean floor allowing them to hide from their enemies, killer whales and sometimes scuba divers. Hammerheads mostly stay along continental shelves and coastlines, but on occasion they are found in the deep ocean cruising near the surface. Sharks have adapted to living in a wide range of aquatic habitats at various temperatures. While some species inhabit shallow, coastal regions, others live in deep waters, on the ocean floor and in the open ocean. Hammerhead Sharks are exotic and cannot be kept as a house pet, but they can be found in many aquariums.
Many animals, whether they live in the ocean or the arctic are affected by climate change. Climate Change affects everybody in the world, even though some choose to ignore it, which is why it would be in humanity’s best interest to come together and find a solution. Burning fossil fuels and the increase of greenhouse gases is causing the earth to warm. Although this gas is the source of the problem we still need it, without this gas the earth would be very cold. What the greenhouse effect is a layer of gas that surrounds the earth,
Journalist Ashley Pierce observed that, in the wild, male orcas live to an average of sixty-five years while females live an average of ninety years. The natural environment creates more than double the lifespan faced in captivity (Pierce 1). Orcas live a shortened lifespan in captivity because the whales can not handle the lack of space given. Over a period of the orcas’ life in confinement, results in the bodies shutting down more and more every day. The Beacham 's Guide to the Endangered Species of North America, expresses that, orcas venture throughout the Pacific Ocean within the whales lifespan (Killer Whale 1).
