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.
My Introduction to Jared I was taking a walk on the beach to clear my head, when I saw an animal that look like it could be a small seal struggling in a net. When I got close enough to see it clearly, I noticed that it was in large fishing net of sorts. I walked up slowly from behind, and saw that the net was digging it to the skin around his neck and that it was extremely close to choking it. I looked for the sharpest rock I could find and tried to be as gentle as I could while sawed at the coarse rope.
There are two points of view of the evolutionary history of the seal, the first view is the eared seals came from a bear like ancestor and the earless seal came from a otter like ancestor due to some similar function of the internal and external organs . The second view is that seals came from the monophyletic group and in a certain point they share a common ancestor. There was an animal called the enaliarctos and it was the last common ancestor of the seals. This animals spent more time on land than in the water than any other pinnipeds. The enaliarctos swim in the water while using both the foreflippers and hind flippers.
Good Morning congress Men and Women. Today Destiney Macario, Yesenia Garcia, and Valeria Herrera are giving a speech about how to help the Marine Otters. The Marine Otters are endangered because it is classified as Endangered on the IUCN Red list. The Marine Otter is important because they are a keystone species,their critical importance to the health and stability of the nearshore marine ecosystem.
Cheating on the Beachmaster by Rebecca Kessler has explained an intriguing behavior of female Southern elephant seals. The entire species of elephant seals are well known for their polygynous mating behavior, in which one male elephant seal dominates several females until another stronger male elephant seal dethrones him. This process involves violent fightings among the males and many other brutish behaviors. According to Burney J. Le Boeuf, a marine biologist studies elephant seals for years at the University of California, male elephant seals have the “habit of biting the neck when copulating”. Meanwhile, female elephant seals and their pups are expected to very vulnerable and independent because of their relatively smaller sizes compared to those of the males.
SEA OTTERS The sea otter is a marine mammal that lives in the northern and eastern coasts of the North Pacific Ocean. They are the heaviest members of the weasel family but are some of the smallest marine mammals. The sea otter has no blubber and the main way to keep warm is its thick coat of fur which is not like most other marine mammals. Did you know the sea otter has 150,000 strands of hair per square centimetre, because of this the Sea otters have the thickest fur of any mammal.
The Sperm Whale looks like a plain whale and it is just like any other whale with some difference. The name of the Sperm Whale is the weirdest thing about it, I think. To discover this you will need to read a bit. The Sperm Whale or Physeter Catodon is like the legend of Moby-Dick!
Loggerhead sea turtles face many dangers including artificial lights, which contribute to their endangerment. The most prevalent way loggerhead sea turtles are being threatened is by human interaction. Humans turn on lights by the beach at night sometimes in turtle nesting season, and this can influence female turtles to avoid the beach, where they need to lay their eggs. (“Please turn your lights off, the turtles are nesting: ensuring that federal, state, and local laws help guide endangered marine turtle hatchlings in Florida to the right source of light”). However, there are some actions humans can take to help prevent endangerment of sea turtle hatchlings.
Decline in Sea Otter Population During the pacific maritime fur trade in 1969, sea otters were hunted until they were almost extinct. After that incident, sea otter hunting was prohibited by international treaty in 1911, because of this a dozen remnant colonies survived. While the North Pacific Ocean recovered at rates of 17-20% in the first year, the population in California hasn’t grown at more than one-third of that rate and they are currently listed as threatened under the Endangered Species Act. Even though the sea otter population in California is declining, the geographic range of the population is expanding to the north as well as the south and its brought sea otters in the south closer to the potential effects of oil and gas development,
In 2013 the controversy of marine mammal captivity was brought into a new light because of Blackfish, a CNN-produced documentary that took the United States by storm by showing a different side to the family-friendly park shows. No longer were killer whales viewed by all as cute stuffed animals to be played with and put on display, but as intelligent and sentient creatures who have been affected significantly by their continued imprisonment. The depth of their social relationships, behaviors, and mental capacity, perhaps only second to that of a human 's, results in the conclusion that orcas are not being protected, as institutions like SeaWorld claims, but are being hindered in their growth of their innate behaviors. This topic has been the
