Oil is the fuel that makes the world turn, powering nearly everything in history from candles and lamps, to modern day vehicles and factories. Before the human race discovered its location in the ground during the mid-to-late 19th century, it was first harvested from whales. Prior to the eruption of the whaling industry during the 17th century, “Marine biologists estimate that there were as many as 4.5 million of the largest whales, plus millions more of the smaller whales, which includes their close relatives, the dolphins and porpoises” (Murphy 10). By the early 20th century, researchers expect that humans were killing over fifty-thousand whales a year, this staggering number brought many species near extinction (Home). Accurate estimates
The largemouth bass reproduces in the spring. To the largemouth basses spring time is typically when the gets to be around sixty degrees Fahrenheit. The females lay their eggs in the nest that the males have created and leave the males there to guard it. The females generally lay about 3,000 eggs per nest, but research shows that some of them have laid up to 6,000. (Becker,
It’s believed to have been between forty to seventy feet long and evolved from the Cretolamna appendiculate. They were only alive for the short period of 16 million to 1.6 million years ago, in the Cenozoic period. They lived in warm waters and most likely preyed upon whales. Megalodon teeth were found in Africa, Australia, Europe, Japan, India, and the North and South Americas. Based on its characteristics, the Megalodon and the Great White sharks are related, but are not direct descendents.
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.
The blue whales are described as the creatures with the largest hearts. While young, they live in a pack with many others, but as they grow older, they depart the group with a partner. In “Joyas Voladoras,” Doyle states that “the animals with the largest hearts in the world generally travel in pairs” (Doyle). Whales may easily feel like they can be independent; however, they choose instead to open themselves up to one partner. From the passage, it can be concluded that the whales choose a partner to ensure they have someone to rely on and cherish life's unexpected moments with.
Sharks have been swimming the world’s oceans for more than 400 million years - 100 years before the first dinosaurs appeared (Griffin et al., 2008). Sharks fall under the kingdom Animalia, the phylum Chordate and the class chondrichthyes. There are more than 400 known shark species found in the ocean (Musick and Musick, 2011). In the ocean, sharks help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011).
The whales are highly intelligent and use sounds to communicate with each other to find their way. But when people take and capture the whales to put them in captivity, they break apart the groups and, the whales get separated from their group or their family. The text also states, “More than 210 belugas, including 31 in the United States, live in aquariums and zoos around the world. The Georgia Aquarium has asked for permission to bring 18 more belugas into the U.S. 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?
The journey took 62 days, and spread over 745 miles. Why it Migrates It was shown that the Hammerhead shark mainly migrates when it is following food, such as the Mahi-Mahi. Life Cycle Hammerheads are on their own from the start of birth, so much so, that when they are born, they swim away from their mothers to avoid being eaten. The oldest Hammerhead shark ever recorded was 31 years old. Summary The Hammerhead shark is a very interesting creature, which we do not know much about.
An article on whaling by Photovoices states, “Many paledang (whaling boats) have been sunk by injured whales trying to escape the harpoon. In some cases, the whale has even crashed its head into the hull of the boat, smashing it to splinters and causing it to sink with the terrified whalers struggling for their lives on the open sea”. This quote shows the dangers of whaling because it is common for men to be injured at sea. Whales are enormous creatures whos instinct is to fight for their lives if they are in danger, leading them to cause destruction on ships and kill the men who hunt them. Once the whale is dead, the task of bringing the whale towards the ship is even harder.
However, when the whales are put into tanks they experience many more dangerous medical conditions. “Killer whales are known for their impressive dorsal fin, which in males can reach 1-1.8m tall. But, in captivity, they collapse”(Warley). In Seaworld most of the whales have collapsed fins that are turned over and are no longer straight. In the wild only one percent of dorsal fin collapse happens among whales.
