“By the 1800s, whaling had become a major industry that impacted the entire world” (Currie 9). As the world’s population increased, so did the necessity and value of a whale’s carcass and the resources it produced. “A single large whale contained tons of meat, which could be dried to feed a village for months” (Murphy 10). “American whalers were especially interested in sperm, right, and bowhead whales because these three species had a particularly thick layer of blubber” (Currie 6). Whale blubber was eventually processed to become oil- an incredible resource in a multitude of areas such as the production of soap, as well as light and heat when burned as candles or oil lamps‒and one of the world’s strongest desires.
Yellowtail is a highly prized game fish. Description: The species are long with streamlined bodies of greenly blue color on the dorsal surface shading to silvery white beneath. Fish fins are yellowish. The Yellowtail Kingfish can grow up to 2.5 m as total length and can weigh up to 70 kg with records close to 100 kg. However, most caught off piers are fish under 5 kg in weight.
Habitation also tends to be underground, which helps in trapping the cold air out of the premises. Historically, their tools and technology we highly sophisticated, using a variety of stone, wood, ivory and bone tools, mainly used for carving, drilling, sharpening, inscribing, and butchering. Lines, lances, and lines are still fundamental in the bowhead whale hunt. The value of trade increased enormously by the arrival of the Europeans, having
Changes in predator abundance can cause cascading effects to the ecosystem structure, functioning and resilience (Baum & Worm, 2009). Due to the sperm whales’ large body size, large population size, high trophic level and potentially important role in top-down control of cephalopods, the impact of their reduction may be more significant than that of other species. North Pacific sperm whales are significant cephalopods predators. Removal of sperm whales in the North Pacific could lead to dramatic increase in abundance of large squids, subsequently leading to the decline of sardine landings (Croll, Kudela & Tershy, 2006). This could majorly tip the fragile balance of the marine
Cetacea are one of the most unique orders of mammals. They include the largest marine animal that has ever lived which is the blue whale, the intelligent dolphins, the tusked narwhals and the singing humpback whales – almost eighty living species in all. Even though a lot of hunting has been done to the family of Cetacea, observations has been dictated that its number are slowly increasing. The oldest fossil whales are grouped together just for the convenience of others. Archaeocetes are the oldest whales and it shows several differences to the modern whales.
Both the humpback whales and the blue whales are extremely vocal mammals, their beautiful and mysterious songs travel great distances across the ocean; the blue whale, both the Humpback and Blue whales are apart of the class of baleen whale; while, the humpback whale population isn’t having trouble maintaining its numbers, the blue whales, whom, had previously been plagued by poachers, causing them long-term damage to their population. Both the Humpback Whales and the Blue Whales produce truly unique songs and vocalizations, that create sound waves for miles around. There are theories that the vocalizations are a form of inter-species communication between the intelligent mammals. Only male Humpback Whales sing, and the song is usually heard during the winter mating season, bringing scientists to the assumption that it might be used as a mating call to attract females. Humpback whales may sing for over 24 hours, nonstop.
Lionfish are damaging the communities that live in coral reefs. If lionfish overtake a coral reef, they can consume over one-hundred types of species of fish. Also, the fish that lionfish consume are necessary for habitat health because they regulate algae. Lionfish have been known to exist in various new areas including Gulf of Mexico, the Caribbean, and the Atlantic Ocean (Morris, J.A., Jr., and P.E. Whitfield).
Why is killing sharks bad? Sharks play a vital role in the oceans in a way that the average fish does not. Most sharks serve as top predators at the marine food pyramid, and so play a critical role in ocean ecosystems. Directly or indirectly they regulate the natural balance of these ecosystems, at all levels, and so are an integral part of them. As they usually hunt old, weak or sick prey, they help to keep the prey population in good condition, healthy and strong, enabling these more naturally fit animals to reproduce and pass on their genes.
Whaling Through the discovery of the “offshore ground” in the Pacific Ocean, during the 1800s, the whaling industry increased in size and revenue. Many coastal cities such as New Bedford and Nantucket in Massachusetts were well on their way to becoming some of the richest towns in America. However these profits were at the expense of their own men, who left their families for years of arduous labor, resulting in meager pay. Life aboard a whale ship was extremely dangerous due to diseases, starvation, and the act of catching and processing a whale. Prolonged time in the ocean caused many whalers to become sick with scurvy, making their lives at sea difficult.
The whales were captured off the coast of Russia.” I am starting to wonder, why do they want to bring more whales and capture more? They already have a bunch! Other people might say that they are fixing the tanks to make it more natural. But I argue, can they really make it as natural as the habitat? The ocean has many different kinds of food for the animals, they can live in their family or swim with their groups, (pods.)
