Does the amount of blubber an Hourglass Dolphin, Lagenorhynchus cruciger, has depend on the environment it inhabits? Introduction Lagenorhynchus cruciger, also known as the Hourglass Dolphin, is a small dolphin found in the Antarctic and Sub Antarctic waters, which tend to be anywhere between -2 and 10 degrees celsius in temperature. As mammals, they are warm-blooded, produce milk, give birth and take care of their young. The Hourglass Dolphin is black and white in colour, with some shades of grey, this pattern resembles an hourglass. They feed on mainly fish, squid and crustaceans.
For the diving depths of the killer whale, it has a uniform diving pattern. Most of the dives was around 50 meters, and they usually do not reach the bottom of the sea. Unlike those of graph A, each dive has almost the same depths, and the orca had a non-stop diving pattern. It reached 50 meters then immediately went back to few meters beneath surface, then few minutes later it started diving again. This pattern went on without any changes for the three hour period.
Turning points can challenge your life at times. It can make your life better or worse. This idea comes up in Hatchet, a fiction by Gary Paulsen, Guts, a non-fiction by Gary Paulsen, and Island of the Blue dolphins, a fiction by scott o’dell. These stories all have turning points that affect them in the same way, doing so, they change their lives and things around them.
Imagine, a 22.5 feet long killer whale that weighs 12,000 pounds, slammed and dragged a person in the water who only weighed 125 pounds. The image is gruesome but that’s what happened to SeaWorld trainer Dawn Brancheau. A respected 40 year old who fought hard to stay alive against the largest orca in captivity. Accordingly to witnesses Tili (short for Tilikium), the Orca went wild during the Dine with Shamu Show, then attacked and killed Dawn. The event shocked everyone because Orcas are usually very friendly but Dawn Brancheau was the third victim of Tilikium.
Orcas’ Behind Closed Tanks Imagine you are a four to eight year old child and you are on vacation with your family entering into a SeaWorld. The excitement has been built up from the commercials that show you these huge and majestic animals that are not like the everyday animal you see on a daily basis. The commercials have a way of taking your imagination to another level, and any child even an adult is at awe with the level of performance these orcas’ are putting on. Amongst the magic, laughter, and adrenaline that you feel you don’t question whether or not these wild animals should be contained like they are.
Island of the Blue Dolphins written by Scott O’Dell is about native American siblings named Karnara, Ramo, and Ulape. The three siblings live together on an unknown Island that has mostly filled with dolphins and otters, but one-day Russian soldiers come and kill the otters for their pelts so Karnara and siblings are trying to save them. Woods Runner by Gary Paulsen is about a 13-year-old named Samuel Smith living in Pennsylvania and is trying to survive the Revolutionary War while on a quest to find his parents in New York after some redcoats held them, Hostage. Woods Runner teaches us to know who to trust and be aware of what you're doing.
For example, when an orca gets hungry it no longer has the ability to swim and search for it's own food. In captivity orcas must learn to rely completely on their trainers, an instinct that does not naturally exist in an orcas brain. Due to the fact that the trainers need the orcas to trust them, they make sure to only give the orcas food after they have performed a task, or have just completed a show. While watching the orcas perform, it can be noted that most of the orcas dorsal fins manage to not stand up straight. In the wild, less than five percent of the orca population struggles with a collapsed dorsal fin.
According to “How did whales become do large? Scientists dive into marine mystery” by Nicola Davis, the blue whale has a body the length of a jetliner, a heart the size of a car and a tongue the weight of an elephant. Researchers now say that they might have found the solution to the mystery behind why baleen whales-a group that includes the blue whales, became the largest animals on the planet. Scientists say that the massive growth which was driven by changes in the distribution of oceanic food and happened just 2 to 3 million years ago. Graham Slater, an evolutionary biologist and co-author of the research from the University of Chicago says that baleen whales have only been giants for one-tenth of their 36-million-year evolutionary history.
Article Review The article ´´ Surviving Rescue: A Feminist Reading of Scott O’Dell’s Island of the Blue Dolphins´´ by Diann L. Baecker published in Children’s Literature in Education in 2007 critically analyzes the content and main character of Island of the Blue Dolphins. The analysis includes a feminist approach and focuses on the theme of survival.
The species I will be focusing on is called, "The Chilean Dolphin, which is also known as, "The Black Dolphin. " "This type of dolphin are small cetaceans with a stocky body shape and blunt beakless heads". "They measure about 1.7 m long on average and reach 60 kg in weight". Jefferson, T.A., S. Leatherwood, and M.A. Webber, Chilean Dolphins, MarineBio Conservation Society, http://marinebio.org/species.asp?id=348.
Bottlenose dolphins communicate by using a number of squawks, chirps, and clicks. Some even have "talked" on the phone. That's right! During one study, researchers in Hawaii listened as a mother dolphin and her baby—swimming in separate tanks—chatted to each other through a special audio device.
Whales in captivity have become too much for humans to handle. Many of the pools that they are kept in are far to small to accommodate their need for exercise. The small pools can also cause a large amount of stress for these animals as well. Sometimes these animals, like dolphins, are kept in captivity for research. After being in captivity for too long
The Humpback Whale (Megaptera novaeangliae) is one of the largest of the Cetaceans. They are fairly well known, even outside of the scientific community. They are identifiable by their dark grey dorsal color, white underbellies, very long pectoral flippers and by their habits of breaching and raising their tales above the water before diving. Their range expands tropical, temperate, and sub polar waters all around the world. They migrate in search of breading grounds and feeding grounds.
Oh the excitement, fall rush of freshman year. You’ve been waiting for this all summer. You got your outfits coordinated for each day of the week. You also have positive expectations. The week is finally here and your journey begins.
As an animal with relatively high intelligence, some believe that keeping dolphins in man-made tanks are unethical because it prohibits them from performing behaviors that are common in dolphins in the wild. These dolphins live up to 30 years in small confined tanks that hinders their movements, much like a person spending the rest of his life in a bathtub-sized space. They slowly develop symptoms that suggest chronic stress, and might even attack human trainers out of frustration or aggression. As mentioned previously, killer whales are highly intelligent animals that can communicate with each other and swim up to 100 miles a day.
