Gray whales are a part of the Baleen Whale family, baleen whales have two blowholes, while toothed whales only have one. Gray whales have rough and short baleen, have no dorsal fin, and only have two to five ventral grooves on the lower jaw. Like many marine animals, gray whales also migrate seasonally. The shape of the gray whales’ torso is the reason why they can dive through water easily and without having the “drag down” feeling. They also have blubbers that can warm them up until the time to migrate. Another adaptation of the gray whales is that they change their feeding styles in order to survive through the climate change and other changes. They usually take a 22,000 kilometers long round-trip journey every year, which is also the longest migration of the mammals. …show more content…
They breed and give birth in the warmer tropical lagoon areas that are along the west coast of Baja California and Mexico.
Their feeding usually occur in the summer due to the long hours of sunlight, which creates much food for them to eat. Without these food, the gray whales cannot survive their long journey of migration. Gray whales migrate because they cannot find as much food and give birth to their babies that cannot survive in the cold water, therefore they migrate to the areas with warmer water. Gray whales were once on the list of endangered species, but were removed in 1993. Although they are removed from the list, the gray whales in the Western Pacific near Japan are endangered. There is also a treaty, called the International Whaling Treaty that banned the taking of gray whales, which help increased the number of the gray whales throughout the years. Gray whales still need protection from human because it is possible for them to become extinct without any
protections.
A hero is someone who will attempt everything in their power to help others and risk everything they have to help others. In the movie, The Whale Rider, you can clearly see all the elements of The Hero’s Journey. A young girl named Paula Apirana, is living in a small village with her grandparents. Paika’s dad, who is living in Spain, returns to see Paula and proposes that she should come live with him. She declines the offer and decided to stay with her grandparents. Paula then secretly tries to learn the important ritual, that only males are allowed to learn. Her grandpa, Paka, gets extremely angry at her until he realizes that she is the “chosen one” to perform the ritual. Paika goes through many difficult challenges, however she manages
The quest to gain international agreement on ethical and legal norms for regulation of whaling has had a long and troubled history. The modern phase of global concern over whaling ethics and conservationist management originated in 1946, when the International Convention on Regulation of Whaling was signed. Thus the International Whaling Commission was created. The International Whaling Commission was designed to control and mandate the whaling industry. From it’s beginning as simply a whalers club with scientific guidance, to the current day conservationist body; the IWC has undergone many revisions and transformations since the start. In 1982 the IWC voted to implement a “pause” on commercial whaling (which is still in effect today). Which major whaling nations, Japan, Norway, Peru, and the Soviet Union (later replaced by Russia) lodged formal objections, due to the fact that the moratorium was not based on advice from the Scientific Committee. One major disappointment of this regulation was due the fact that the moratorium only applies to commercial whaling. Thus, whaling under scientific-research and aboriginal-subsistence is still allowed. Japan and other countries have continued their hunt in the Southern Ocean Whale Sanctuary under the “scientific research” loophole. However, environmental activist groups openly dispute the claims and continue their rally to end the whaling industry for good.
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.
In the 19th century the Pacific Gray Whale was nearly hunted to extinction when their products were in high demand. At the turn of the century, there existed only a few thousand of these precious whales. Soon after, the whales were placed onto the endangered species list where they were under the heavy protection of numerous national laws and international treaties. In 1993 the number of Gray Whales climbed to a miraculous 21,000 and by the end of 1994 the Pacific Gray Whale became the first mammal to be removed from the endangered species list. A few months after its removal from the endangered species list, the primary breeding and calving grounds of the Gray Whale, located in Baja California, was chosen by the Mitsubishi Corporation to become the worlds largest salt harvesting center.
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 origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.
As shown in the figure A, a blue whale has a mottled bluish with broad flat head and a small dorsal fin located near the tail. Figure C furthers shows the morphology of a blue whale. A blue whale can have about “320 black baleen plates in the mouth, 2 blowholes, and many blue-gray white spots” (ZoomWhale). A blue whale is toothless, and this can be a problem when scientist tries to date the age of animal based on it’s teeth. However, it is estimated that a blue whale can expected to live past 50 years (NOAA and World Wildlife).
The Makah tribe wants to hunt gray whales, which is a significant part of their culture, as evidenced by most, if not all, of their traditional dances, songs, and arts reference gray whales and the ritual hunt of them. The Makah, for about seventy years, agreed to temporarily stop hunting gray whales due to how close they were to becoming extinct, but now that they have officially been taken off of the endangered species list, the Makah wish to once again take up their yearly hunt. Many on the anti-whaling side oppose the hunt, because of concerns that the hunt will either push the gray whales back into the endangered or vulnerable species list or that the Makah hunter won't have any way to tell if the whale they kill comes from a year round
Whales generally live 20-40 years and usually have a 9-15 month gestation that leads to usually 1 offspring("Whales"). Since whales are mammals whom live underwater, they have to plan when they breach to the surface to breathe through their blowholes. It is very difficult for whales to sleep because " they can not afford to fall into an unconscious state for too long, since they need to be conscious to break the surface in order to breathe"("Whales"). Whales use echolocation to detect their surroundings and communicate with other whales. When whales communicate they use lyrical sounds. It is also believes that whales slap their tails to warn other whales about danger("Whales"). Back in the the days before oil drilling, people killed whales and used the blubber of a whale for oil. Now they have to face the dangers of poaching, climate change, and underwater sonar testing("Whales"). Many people whale watch when humpback whales visit each year from November to
Humpback whales breath voluntarily, unlike humans. Since they have to remember to breath, researchers believe humpbacks sleep by shutting off half of their brain at a time. Like orcas and dolphins, humpback whales have noses at the top of their head called blowholes (Animal Planet). Humpback whale calves do not stop growing until they are ten years old (National Geographic). They breed, give birth and care for their newborn calves in the warm waters of Tonga. Instead of teeth, humpbacks have baleen plates, they are brush-like strands of bristle that trap there food until it is swallowed. They have very odd mouths that curve downwards, like an eternal frown. Humpback whales are amazing marine mammals (Big Animal Expeditions)
...nd also the earth. If whales become extinct then there could be a rapid increase of small aquatic animals that could harm the marine food chain then further kill marine ecosystems. This is because whales help regulate the flow of food by helping to maintain a stable food chain.
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
It also has a lateral line which senses movement in the water. Whale sharks amazingly have 350 rows of the teeth which make the total 3000 teeth. Each tooth is 3 mm thick. The mouth of a whale shark is 4 Feet wide (120 cm). A whale has a complex filtering system. Whale sharks have 3 ridges that run on the side of large gill slits. The spiracle is located near the eye. It is used to breathe. Its skin is 10 centimetres thick. The top fin on the tail is slightly larger than the bottom fin. The tail of the whale shark is half mooned shaped. Whale sharks are slower that most sharks. They have to move their whole body to swim rather that tail. Whale sharks grow up to 9 – 12 meters, when they are adults. The skin of the whale shark is yellow or white blotches. They weigh up to 12,500 kg. The heaviest whale shark was known to weigh 34,000 kg. Whale sharks are curious creature and are friendly to
