The main problem which causes the most damage to the Blue whale’s population comes from whaling. Blue whales and other species of whales all weigh tons, meaning they can provide enormous amounts of meat, blubber, skin and other body parts with a single catch. It is believed that an average sized whale contains “152 tons of more or less edible material” and with some calculations, a single whale can provide “604,000 people [with a] single meal” (Nessen 1), and this excluding the other benefits such as blubber and skin which can be used in other applications. As a result, during the 1900s large amounts of whalers who were motivated by the whales great value to catch and slaughter more and more Blue whales (National 3). Due to such aggressive whaling, during the period of 1900 and 1960, more than 360,000 Blue whales were slaughtered for oil and meat (National 3). This and other factors have caused the Blue whale population to decrease down to 10,000 to 25,000 on average based on different sources. The fact that Blue whales are found in all seven oceans does not help either since many more countries can partake in such disgusting and profitable business. Another major problem on this topic are nations such as South Korea (SK). Whaling is banned internationally( National 3); however, due poorly written laws, poor enforcement, and different viewpoints, whalings still take place. In South Korea “commercial and subsistence whaling are both illegal;” however, “domestic sales of…

Bluefin tuna have suffered major population declines due to overfishing. Recent scientific research discusses various ways to implement management techniques to target the rapid declining population levels of Bluefin Tuna. However, much of this research demonstrates a substantial level of uncertainty about the basic biology of Bluefin Tuna. In particular, a lack of knowledge about the migratory patterns of Bluefin Tuna hinders the success of many proposed management techniques. Thus, it is…

The explosion of this industry placed additional demands on fishing, namely of bluefin tuna. While essential to restaurants across the world, these animals are in danger of extinction from overfishing. These apex predators are critical to the marine food web. Our level of consumption of undomesticated species…

Why do you suppose two Betta fish always fight when placed into a bowl of water? It could be inferred to be a territorial instinct, or probably a way to fight for mates, but whichever way you look at it, they always seem to fight when placed together. Beta fish, much like people, can sometimes fight for similar reasons, but sometimes it can be for more personal reasons like religion or values. In Chinua Achebe’s book, Things Fall Apart, he tells the story of an eighteenth century African…

Blue Whale The blue whale Balaenoptera musculus is a marine mammal belonging to the baleen whales Mysticeti. The blue whale is the largest animal to have ever existed. The blue whale can mature up to 100 feet long and can weigh up to 173 tons. The diet of the blue whale consisits of mostly small crustaceans known as krill but also eat small plants and fish. The blue whale’s body type is long and slender and their body shade varies from greyish blue to a dark navy blue. The whales dorsal can…

According to the article “Search for the Missing Sea Otters: An Ecological Detective Story” by Mary E. Allen and Mark L. Kuhlmann, the sea otter population has been decreasing at a rapid pace since the 1990’s in Aleutian, Alaska. This is demonstrated by article “What Could be the Cause of Decreasing Otter Numbers” which states that in 1997, the decline of the sea otter population had increased to about 90%. They hypothesize that the decrease in the sea otter population has been caused by their…

Blue Whale My animal is the Blue Whale. It is an endangered species. Endangered means that a animal or plant in danger of extinction in the near future throughout most or all of the world. Threatened means any species likely to become an endangered species in the near future throughout all or a significant portion of its range as defined in the Endangered Species Act. Blue whales are mainly found in open oceans from the icy waters of the very near Antarctica in the Southern Hemisphere to the…

Blue whales are interesting animals. The physical characteristics of blue whales set them apart from many animals. The habits of blue whales, including their diet, migration, and mating, are unique. The endangerment of blue whales has been a changing topic over the years. Blue whales are the largest animals on Earth today, they even beat the dinosaurs. A blue whale weighs about 200 pounds and it’s length is about 3 school buses back to back, meaning it can range from 82 to 105 feet.…

Seahorses Did you know that seahorses are the only sea animal where the male gives birth instead of the female. What about the fact that seahorses can eat up to 3,000 shrimp per day. While they are sleeping they wrap their tails around seaweed so they don’t float away. Of course, seahorses are very interesting and one of the most interesting animals in marine life. This paper will explain the birth,food,and adaptations of a seahorse. First of all,this is all about a seahorses…
