One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times
known as, the whale shark. The whale shark is vey unique because unlike normal sharks, the whale shark is a filter feeder and so, does not have use of its teeth. The whale shark is also about the size of a bus. However, like many animals in the world today, they are considered vulnerable according to the IUCN. They are seen often in the tropical areas, but many behavior and movement mechanism of the whale shark are still unknown. Physical description: The morphology of whale sharks is mostly similar

Animalia: a taxonomic kingdom that includes living and extinct animals Chordata: a taxonomic phylum that includes all the animals that have a spinal column (backbone) Chondrichthyes: a class of fish that have cartilaginous skeletons Orectolobiformes: an order of carpet sharks Rhincodontidae: a family of small-toothed sharks Rhincodon typus: the genus and species of whale sharks TABLE OF CONTENTS 1. CLASSFICATION
all the forms of sharks is how long they have been living on earth. With having over 400 000 million years to diverge from their ancestors, sharks now have such a diverse range of characteristics and abilities in order for them to survive. Sharks are also very geographically distributed around the world. This is due to living in the ocean which occupies 70% of the earths surface, (Ocean Service, 2013), thus giving sharks the ability to migrate globally. Furthermore, some sharks have the ability of
rewarded and he is reunited with his son. Through the help of unlikely sources like a whale, a turtle, and a pelican, Marlin regains what is most precious in the world to him. These characters played a key role in Marlin’s journey but it is clear that Dory was the most critical to the pending success of Marlin’s pursuit. This fish that forgets what she is doing every five minutes and finds camaraderie in sharks, whales, and jellyfish is the most significant source of help Marlin has. Marlin and Dory’s
study the magnificent creatures we know as sharks. Unfortunately, along with the recent influx of curiosity regarding sharks and shark species has come a development of taste for the shark and the scarce resources it provides. Shark populations are disappearing faster than ever before, and studies about sharks have come along just as these cartilaginous fish fade from the face of the planet. Shark populations are crashing due to many reasons. For one, sharks have oftentimes been depicted as bloodthirsty
his overcooked whale steak. Not only does Stubb ask Fleece to "preach" to the sharks who are making a considerable din eating the dead whale chained to the ship, but he compares Fleece's inability to "correctly" cook a whale steak to Fleece's un-Christian ways. This passage is an excellent example of the theme of the hypocrisy of religion in Moby Dick. Before Stubb calls on Fleece, Ishmael compares the actions of the shark to the actions of man. He first compares Stubb to the sharks: "Nor was Stubb
Shark scales, or dentricles, are roughened and will scrape if felt to wrong way, much like sandpaper. The true purpose for this is unknown, although it is thought the shape increases streamlined properties. Sharks have two pairs of fins and four singular fins, all of which are used for swimming or balance. The rear pelvic fins in males are lengthened to aid in reproduction. The oil in the shark’s liver adds buoyancy, due to the lack of a swim bladder. The gills are protected by gill arches and slits
savage eyes. This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because
Shark! For many, their size, power, and great, mouthwatering jaws fill us with fear and fascination. Not for me, I’m bewitched by them. Sharks kill only a few people each year, but media coverage and movie representation of attacks have marked sharks as voracious killing machines. Our fears—and appetites—fuel an industry that hunts more than 100 million sharks each year and threatens to purge these vital predators from the oceans. The shark is an enchanting creature, over 400 different swim in the
INTRODUCTION Although sharks belong to the class Chondrichtyes, there are many different types. Sharks arose about 350 million years ago and have remained virtually unchanged for the past 70 million years and still comprise a dominant group. It is thought that sharks almost certainly evolved from placoderms, a group of primitive jawed fishes. It took a long series of successful and unsuccessful mutations with fin, jaw positions etc to give us all the different designs of sharks around today. When asked
explanation on how one of nature’s apex predators, the shark, and how the way sharks hunt and track down their prey. The hunting process for sharks will be explained in sequencing order starting from how sharks sense their prey, to how the way sharks stalk their prey, and what happens when sharks capture their prey. Also a brief explanation will be discussed about how two peculiar species of sharks, Hammer head sharks and Long nose saw sharks, about their body shape, their diet plan, and how the way
mind when you think of sharks? Sharks make people think of death and fear. As you will be able to see after i discuss types of sharks, their habitat,the food they eat, and their intelligence. They don't seem as bad as you think so. First sharks live a habitat under the water in the sea. Sharks live in many different oceans. They live in the the pacific ocean, Atlantic, Indian,and the Arctic. Mostly all sharks live in salty water, but some sharks live in the river. Sharks live in coral reefs under
Fossil Discoveries in Kansas Did you know, in the state of Oklahoma it is against the law to either hunt or catch whales? Sounds sort of ridiculous when you think logically about it, but according to paleontologists it isn’t that far fetched. Over 65 million years ago Kansas, including the whole Midwest Region of North America from the Arctic Circle to the Gulf of Mexico, was covered by the Sea. Due to the continental uplifts of the mountain ranges in North America during the Pangaea stage
Sharks Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation
How shark-skin denticles inspired the construction of antibacterial surfaces; how jellyfish tentacles influenced the design of a technique for snagging rare cancer cells circulating in the bloodstream; how mussel proteins that harden underwater to attach the mollusks to rocks can serve as an effective surgical glue; If I could reveal anything that is hidden from us, at least in modern cultures, it would be to reveal something that we've forgotten, that we used to know as well as we knew our own
Greenland Shark Sharks live in almost every part of the oceans, from coastal environments to deep-sea habitats. They also live in the warm waters of the tropics to the cold frigid waters of the polar region. The Greenland shark, also known as “somniousus Microcephalus,” lives in the dark, cold waters of the North Atlantic (I 65). The Greenland shark belongs to the order Squaliforms, more usually known as dogfish sharks. There are 70 species in this order, which includes the spied sharks, spiny dogfish
Shark Conservation Abstract Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind
the WA government continues to support and allow the shark culling off Perth's major beaches. Hi I'm Maya Koentgen, a marine biologist, ecologist and fellow beach user, and I'm here to tell you why shark culling needs to stop. At the moment hundreds of innocent sharks are being caught and killed and why? Because they are simply swimming in their own homes that us humans have invaded. One of the governments main reasons for culling the sharks is because they are coming in too close to the shores
started out going to fish for some dinner, then he caught the biggest marlin ever and it pulled him out in the bay of Cuba even more then he was. After he was pulled out, he hurt his hands and couldn't risk going to sleep because of the risk of sharks. When the sharks finally attacked he lost the marlin which had become a great part of him because he knew that no one would believe him when he told them the size of the marlin. This has to be one of the most memorable fights in a novel that I have ever seen
