(http://www.sharks-world.com/tiger_shark/) The tiger sharks digestive system isn’t that complex. The quelled, which is a tube its food passes through, takes the food into the stomach. As digestion starts the food goes into the intestines. The food that is absorbed by the intestines goes into the liver and nutrients get absorbed. Tiger sharks actually eat whatever they can find.
Are there advantages to swimming in school? The answer is yes. There are many different ways that swimming in schools can help fish. There is safety in numbers, so one way is that it keeps fish safe from bigger predator fish that might try to attack and eat them. Some fish swim so close together they blend in with each other and to a predator it would look like one huge fish, making the predator confused and scared so they swim away.
December 1, 2011 Paul Guernsey College Composition Final Conservation of the Bluefin Tuna Bluefin Tuna, or Thunnus thynnus by its Latin name, is one of the largest, fastest swimming, and beautifully colored fish in the entire ocean. Their coloring is made to camouflage themselves from both above and below with metallic blue on top and shimmering silver-white on the bottom. Their bodies are torpedo shaped and built for speed and endurance while hunting for food, or being hunted (National Geographic). bluefin Tuna are prey only to some marine life such as, some whale, shark, and marine mammal species. With highly migratory species like bluefin tuna, management is complicated because these species migrate thousands of miles across oceans and international borders and are fished by many nations.
HWST 213 Paper #1 Hukilau: An art of fishing in ancient Hawaii Hukilau fishing, literally meaning “to pull the leaves”, was one of the most famous ancient Hawaiian net fishing techniques. It was a process of sweeping the sea with ropes to which bunches of ti leaves had been tied to. Fish became frightened by the leaves and were driven forward toward shore. Ropes were used instead of nets in the deeper waters due to their ability to pass through rocky waters, whereas nets would easily be torn. Nets were used after the fish were herded into the shallow sandy beach areas.
Though the Japanese think the dolphin killings are fine, many others do not. As someone who has always loved animals, I believe that the dolphins killings should stop. The Japanese fishermen use a technique for capturing dolphins called drive fishing. Motorized boats circle around the dolphins and disorient them by creating a "wall of sound". Swimming frantically, they are driven to the shore and then trapped overnight in a small cove.
This makes a red tide very hard to predict or find. HABs have been reported in almost every U.S. coastal state, and their occurrence may be on the rise. One of the best known HABs in the nation occurs nearly every summer along Florida’s Gulf Coast. In this case, the mortalities are caused by exposure to a potent neurotoxin called brevetoxin which is produced naturally by the marine algae Karenia brevis. This affects the central nervous system of fish so that they are paralyzed and can't breathe.
Whale populations dwindled, so whalers looked towards rorquals (baleen whales), but they swam too fast to be caught by rowed boats and they sank when they died. The development of the harpoon cannon allowed a way so rorquals could be killed consistently. Norwegians refined this technology and developed a way of keeping the whales afloat by injecting compressed air into them (McNeill). The profit from hunting these whales was mainly from the whale oil; the oil from the rorquals could be made into margarine and into soap. A by-product of boiling the whale blubber into oil was “glycerin, needed for nitroglycerin which is used in dynamite,” so with the arms
The viperfish uses a process called ‘Bioluminescence’ to attract its prey. E. Its teeth also aid it in grabbing and holding onto prey that it finds while hunting in the pitch darkness of the depths of the ocean. F. The viperfish possesses a hinged skull and extremely large stomach, enabling it to rotate its head vertically to consume larger prey, in addition to the ability to consume large amounts of food when it is plentiful in supply. G. It is known to migrate vertically. Usually located in deeper waters during the daytime, whereas at night it is known to swim up to around 2000 feet.
This shows that he really cares about nature because he realizes how beautiful and sweet the sounds of the whales are. There is also a cruel side of nature as well compared to the beautiful side. The cruel side that shows in this book is the sharks. The sharks come up from the bottom of the sea when the old man is washing the blood off his hands in the sea. The shark smells the blood comes up and attacks the marlin taking a huge chunk of flesh out of the marlin.
Shark poaching is a big concern because it affects the future of sharks and their place of living. Poaching is the process where people get rich by catching sharks on long lines, cutting their fins off, and then dumping the remaining body of the shark back into the ocean to suffocate and bleed to death. Shark poachers seek financial gain and at times religious value, however, by doing so they fail to realize the negative impact that their actions have on the environment and the shark species. “Sharks have made it through multiple mass extinctions on our planet, now many species are going to go the way of the
