Fin

The Fins in this project are based on the Thresher shark. Its tail is shaped like a thresher, and the shark uses it as a weapon to stun its prey. Since this shark is an active predator, its tail should not only be used as a weapon, but also a great source of propulsion. In order to design and compare a fin to this extraordinary shark tail, a simple trapezoid was created to set a base model. Its dimensions are as follow: This fin is the base model designed to set the first data of propulsion, so…

All around the world animals are held in captivity for the sole purpose of gaining revenue through entertainment, but by enclosing these animals in small jail cell type configurations, animals are being revoked of their chance to live and grow in natural environments. Animals who are stripped of their rights and chance to grow and thrive in a natural way usually end up developing physical and mental health issues and are more susceptible to problematic diseases. The use of animals in captivity…

Orcas have their own sophisticated culture and way of life, but living in captivity may not allow them to realize the full benefit of cultural theory. This is not what the founders of SeaWorld envisioned. Therefore, because of documentaries like Black Fish and pressure from animal researchers, activist and those who embrace cultural theory, SeaWorld is moving away from the practice of holding orcas in captivity. This may seem like a potential disaster for such a successful business model and…

Classification – Chondrichthyes is a class that contains the cartilaginous fishes: they are jawed vertebrates with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone. The kingdom of a grey nurse shark is Animalia because the grey nurse shark is a multicellular animal. The phylum is Chordata because it is a large animal that includes vertebrates . The class is Chondrichthyes because it has a cartilaginous skeleton. The order…

to describe the victim of abduction or a hate crime, yet it describes the life of an orca in captivity. Orcas are captured out of the wild and forced to do tricks in order to get their food. Their lifespans are drastically shortened and their dorsal fins no longer stand straight up. Their families are separated and sent thousands of miles around the globe. And for what? The amusement of the average ticket buyer at Seaworld and other similar institutions. This type of torture should not be…

I am part of the wild life in the sea. My colors vary form grayish blue, white, and black. I don’t swim like many fish, with my tale from side to side, instead I move my flukes up and down. When I surface to the top you might swim away. I am calm most of the time, but I can be aggressive. I eat some of my fellow friends in sea. I protect you when you’re helpless. I am known as a protector and guardian to people at sea. In late summer my constellation is shining bright in the sky. I am the…

the top and on its underbelly it is somewhat lighter. The blue whale has a long and tapering body that is muscular when compared with other whales. Its head it a flat U-shape and has a ridge that runs from the upper lip to the blowhole. It's dorsal fin is small when compared to its body size being only ranging from 8 to 70 centimeters. The flippers are around 3-4 meters long with the top being a dark blue-gray colour and underneath a whitish colour (Web.archive.org, 2015). Blue whales feast…

species is unnecessary. Norway only allows whaling of minke whales (fisheries.no, 2013) and said species is considered to have a healthy stock of whales (IWC. n.d.). Japan hunts Minke, Humpback and Fin whales according to Whale and Dolphin Conservation (WDC) (WDC. 2006), with both Humpback and Fin whales being listed as protected…

The Effects of Orcas in Captivity Ever wonder what goes on behind the scenes of the killer whale shows at SeaWorld? So much preparation goes into the shows at SeaWorld. This causes frustration within the whales that can result in whales acting out on other whales and SeaWorld trainers. So, is captivity good for the orcas? Despite the fact that millions of people go to SeaWorld every year to see the killer whales, the animals are actually mistreated. If SeaWorld doesn’t change their ways, then…

withdrew from the IWC. Twelve years later in 2004, they rejoined the IWC. And finally in 2006, Iceland went back to its old ways for good continuing with commercial whaling. They have not been with the IWC since, and killed a total of 148 endangered fin whales and 60 minke whales in 2010. Today, the United States and other IWC country members have tried to persuade the other three countries to end their commercial whaling. After the pressure from the World Wildlife Fund (WWF) and the U.S…
