They have tiger like patterns when they are younger for camouflage in the water which resemble the waves in the water but as they grow older these stripes disappear. These sharks can grow up to 7 meters long. Tiger sharks have five to seven gills on the side of their heads. Their dorsal fin are very close to their tail. (http://www.sharks-world.com/tiger_shark/) The tiger sharks digestive system isn’t that complex.
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.
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. There are also ecological advantaged of swimming in schools. Some fish give off a liquidy slimy substance. This slime helps reduce the friction of water on the gills of other fish in the school and swimming around the school. Fish also swim in the same pattern when they swim in schools.
So I am doing my research paper to know more information about this rare fish The life story of Batoidea page 3 Title: Shocking Discovery! Torpedo Ray in Wellfleet Bay Name of source : http://www.turtlejournal.com/?p=1448 and http://www.answersingenesis.org/creation/v24/i4/sharks.asp Summary : this journal is talking about Ray fish's life style and also about their normal weight , long . On the one hand , this journal also talking some information about where do they live , what do they eat and why do they be killed ? Assess: This journal is very interesting, so I will use the information in this journal for my research paper. Reflex: I really like the journal I’ve just found on internet.
They even have pockets of skin under the forelegs to stash food for their trip from sea bed to water's surface. Using their surroundings, which used to span the globe but are now limited to a few locations such as Japan, Russia, Canada, Alaska and California, sea otters wrap themselves in kelp to prevent floating away while they eat a snack. Kelp is also used to wrap around a pup and keep them close. Kelp beds are a plentiful source of food for sea otters. While a large population of sea otters can wipe out abalone and crabs that fishermen make their living off of, otters were once heavily hunted for their fur.
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.
The temperature they live in is tropical water. It is very hard to figure out the difference between a female and a male because they look alike. The difference between the two is the male has more of a pointed dorsal and anal fins, but sometimes it’s still hard because some females have pointed spines (dorsal). The females have rounded fins. It’s easier to find female parrot fish than male parrot fish.
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.
According to resources.metapress.com, it is very rare to see any adopting families. The mother seals are like the stay at home moms. They nurse their pups at home while the fathers are out at sea bringing back whatever food they can find. Females are about seven and a half feat long, weighing in at 600 pounds when the males are about seven feet long and weigh in at 400 pounds. Defenders.org tells that the Hawaiian Monk Seals live up to about thirty years.
“Whale Wars” is a show about a conservation society who protects whales in the southern ocean from the Japanese Whaling Fleet who hunts whales to sell the meat illegally on the Japanese Market. The Fin Whale is located worldwide from the North Pacific to the Southern Pacific to the Indian, Mediterranean and the Arctic Oceans as well as the Southern Antarctic (WWF, 2007). The Pelagic Zone is where the Fin Whale lives and is a coastal species sometimes living in shallow waters(WWF, 2007). It feeds through the baleen plates in taking large amounts water filtering it through its mouth to in take fish, krill and squid(Harrison, 2005). When it feeds on schools of fish it often lunges sideways in taking the school within several lunges.
