Humpback Whales Humpback whales are amazing mammals and they go through a lot of extraordinary things to be able to survive. There are many whales in the ocean, but the whales that are in the Hawaiian culture areas have many difficulties and most people don't understand why. Humpback whales have the scientific name of Megaptera Novaeangliae, that species of baleen whale is one of the larger species, and adults range in length from twelve to sixteen metres which is thirty to fifty-two feet. They weigh approximately seventy-nine thousand lbs (pounds), and they have a distinctive body shape. These whales get their name from the way they come up for air and show their back dorsal fin. this happens right before it starts moving its flukes, flukes are the tail fins. Lots of people first identify a whale by it flukes. (which is another name for its tail fins). they say humpback in their name but the hump they see is actually a forty-nine feet of back rolling into a sixty-thousand pound plunge into the water. “Its most likely that humpbacks sing to communicate with other whales and to attract potential mates, National Geographic,page6”. Humpback whales grow strange things on their body like hair, these large mammals have whiskers like cats and other animals.the first thing people see is the bump that the hair grows on. Scientist say that they have these to feel things like cat’s and other creatures do.Another interesting fact about this animal is that scientists found out the age of beached whales and ones that have been killed. Marine biologists can determine the age of these whales by their teeth. When they find a dead whale or kill a whale, Marine biologists can also look inside the ear and look at the different layers of ear wax ty... ... middle of paper ... ...ail fins allow whales to propel through the water if necessary. The effects of global warming affects the marine animals alot more than people might think. The sea level rises which leaves whales vulnerable, and they might not be able to adapt quickly enough to survive. As you can see Whales are in this world for a reason, every living thing has a purpose. Although we use these whales to make wax for candles to food on our table. There are isn't a lot of Humpback whales in the ocean and their population is limited due the deaths. Everyone has to take their part in the world, and make it easier to understand that we need them more than we thought. Their way of living and what they have accomplished though there time of life is extraordinary. Their migration and communication is so courageous. Humpbackwhales are what i would call a creation well worth having on earth.
Perhaps once you view Blackfish by Gabriela Cowperthwaithe, you will begin to have an understanding of how the whales feel. The documentary follows an Orca by the name of Tilikum. Tilikum had been involved in three deaths, including a Marine Biologist named Dawn Brancheau, who was killed by Tilikum while performing with him. The film also highlights why keeping whales in captivity is dangerous and also touches on the death of Dawn Brancheau who was faulted for her own death due to her ponytail hanging low. After watching the documentary, I began to analyze Gabriela Cowperwaithes claim; essentially, she doesn’t feel it is right to have whales in captivity because it makes them aggressive and perhaps insane after being held in captivity for so long.
“Whales provide us with the food for our bodies, bones for our tools and implements and spirits for our souls.” “We haven’t hunted the whale for 70 years but have hunted them in our hearts and in our minds.” “Whales are a central focus of our culture today as they have been from the beginning of time.”
Image sitting on the beach one July morning. The sun is beaming down and decide to go for a swim. As you approach the water, you see a whale unusually close. You begin to get nervous as it continues to approach the shore. However, you aren’t worried because you know that they are confined to the sea. As the whale comes near you can see it clearly. Just as you think that it will turn around, the whale walks out of the ocean!
“… building a tank the size of Rhode Island wouldn’t be large enough for a six-ton male killer whale such as Tilikum, an animal capable of swimming 100 miles a day,” states an anonymous whale expert. Whales have been in captivity since 1861 when P.T. Barnum displayed the first live whale that was captured in Canada. However, Barnum had no idea how to care for the mammal and it died after only a week in captivity. (Animal Legal and Historical Center, 2014) Being up close with killer whales could give us some clues about how they interact with each other, including physical behavior, their dialect, and how their pods work together as a family unit. However, what we are finding is that whales who belong in the wild are suffering in captivity. Killer whales have no record of ever harming a human being in the wild. In captivity, there have been many incidents of killer whales harming or even killing their trainers. What would cause them to do this in captivity, but not in the wild? They have been known to resort to aggression toward themselves and each other, in what scientist believe to be a stress induced behavior. (Animal Legal and Historical Center, 2014) Evidence against having these wild animals in captivity is increasing and we need reevaluate the value of capturing and holding killer whales for our educational purposes, enjoyment, and profit.
Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean. It is interesting to know that killer whales have a plentiful diet. It is astounding to see how killer whales behave in the ocean. I plan to tell you about the killer whale, its characteristics, its diet, and its behavior in the ocean as well as the predation of the orca.
Their dorsal fin is extremely long, tampered and pointed in a triangular shape or rounded and curved towards the end. The skull is oval shaped and the beak is extremely short and rounded at the end. The killer whale’s jaw is powerful with teeth that are able to tear apart flesh of their prey. They can withstand the jolting, wiggling and hurtling movements of prey that are trying to escape. The killer whale is born with a single blow hole instead of two. Their flippers are paddle shaped with rounded ends and flukes are tapered back and pointed at the end resembling to a triangle/pyramid
Although the trainers are not allowed to be in the water with them, the trainers still use the same tactics of training. Some of the tricks the whales practice on a daily basis are, waving, showing off their teeth, laying on their side, and squirting water out of their blow hole. The shows still consist of the same concepts and the crowds continue to pay to see the whales do tricks. Whales living in captivity remain in distress and continue to lash out at trainers and other whales in their pools (10 Things You Didn’t
While whaling isn’t nearly as popular today, in this time many men made, or attempted to make, a living in this industry. Despite the hard work, dangerous standards and general intimidation, shipmates were lured into the industry for the high pay. When feeling protected by a large ship, weapons and a fearless captain, it was easy to forget the power of what they were hunting. The sperm whale is the largest of all the toothed whales, with males maturing at an average size of fifty- two feet and sometimes can reach up to sixty-seven feet in length. “It’s twenty-foot-wide tail pumped up and down.” (Philbrick, 2000, 82) The domain of life that the sperm whale belongs to is the Eukaryote. This is because the sperm whale is an organism that is made up of cells that contain a nucleus as well as other structures that are enclosed by the cell membrane. The kingdom that it belongs to is the Animalia. This is because they are multi-cellular organisms. These animals contain other distinct features including; “interior digestion of f...
...ould estimate where they spent most of their time. By the length of the other skeletal bones, the size and shape of the animals could be determined, which also shared insight to its behavior. The largest primitive whales could indeed walk on land, but only did so for short periods because their legs could not take so much weight for long amounts of time. These behaviors allow scientists and paleontologists to understand even more as to how these fascinating and mysterious animals went from ruling on land to taking over the sea.
Orca whales do not like to be taken from their family, held captive for many decades and put with other whales that they do not know. No other living organism on this planet would like to be put through the same thing. Orca whales are highly social animals, they are very intelligent, and are very emotional. If they are kept away from other whales, fed intermittently and received little attention from staff makes them get very emotional and can lead to death of people and the whales. Orca whales should not be held captive; they are beautiful creatures that are not great for people’s amusement and if they are treated poorly, they will act poorly.
Orcas, or killer whales are majestic giants of the sea. They are actually the largest type of dolphin. They have long black bodies with distinct white patches near their eyes. A killer whale can be up to 32 feet or more in length, and weigh up to 12,000 pounds. Females are a bit smaller, but live longer (Gorman). The name “killer whale” apparently came not because it is a vicious whale, but because it preys on whales. They do not have any natural predators, and they are considered the “top dog” of the ocean. Not even the great white shark stands a chance against these superb killers. “Unlike sharks, killer whales are cautious hunters, sometimes spending hours harassing a 1,000-pound sea lion so it can easily be drowned” (Francis). Orcas use many hunting tactics that are unique to their species, which is what makes them invincible.
The short film ,”Humpback Whale Shows AMAZING Appreciation After Being Freed From Nets,” shows 3 men, and a woman are in a small boat, cutting away the net that inprisons the whale. This is a fine example of the value of human emotions enhancing the survival of the whale, that otherwise would more than likely die. After being freed the whale danced a happy dance of sorts, and showed it 's appreciation for valuing it 's life enough to risk their own safety to save it ("Humpback Whale Shows AMAZING
If Australia leads the way to making stricter rules to save the lives of these majestic creatures, the variety of species can recover. Overall the humpback whale has moved from 'vulnerable' to 'least concern' on the IUCN Red List, a list of the worlds species facing the highest risk of extinction. This means that overall humpback whales are less likely to become extinct which is a level needed for all whales. This is a great recovery however it is not enough to restore the marine balance in the oceans. We need at act NOW, in order to safeguard the futures of our worlds whales.
How should these claims be balanced against world opinion - which is generally very supportive of the protection of whales?
The Humpback Whale, Megaptera novaeangliae, is part of the marine mammals group. They are found in oceans all over the world, they live in open waters. Even though they are mammals, they do not live on land (Monterey Bay Aquarium). Humpback whales are known for their magical song that can travel great distances. These gentle giants are omnivores, their main diet is krill. They are mostly found near coastlines feeding on tiny shrimp-like krill, plankton and small fish. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding water closer to the Equator. Humpback whales are powerful swimmers, and they use their massive tail fin, called a fluke to propel themselves through or even out of the water! Mothers and their young swim close together, often touching one another with their flippers with what appears to be gestures of affection. Even though it takes more than one year for a humpback whale to grow fully, mother whales leave them after one year (National Geographic).
