Tiger sharks can be killed by orcas as well. Their hard beaks make a good weapon, which induces blunt end trauma on the shark’s pressure points (National Geographic). The tiger shark is considered the sacred na ʻaumakua (ancestor spirits) by some native Hawaiian people who think their eyeballs have special powers of visual perception.
Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man.
Great white sharks are the main predators in the ocean. The only things that are responsible for the deaths of sharks are Age, Health, Humans and other sharks. Humans are responsible for 70% of deaths for great white sharks. Today there are more than 440 known species of sharks. Great whites only have 2-12 babies at one time unlike others who have hundreds.
Describe the morphological features (external) uniquely distinguishing your chosen species G.cuvier (Tiger Shark) are among one of the largest extant sharks, ranking in size only behind the whale shark, the basking shark (C.maximus) and the great white shark (C.carcharias). The tiger shark on average attains а length of 3 - 4.2m and weighs around 385 - 635kg. Sometimes, an exceptionally large male tiger shark can grow up to 4.5m. Females are larger, and exceptionally big ones can reportedly measure over 5m. (Stevens et al, 1991) The exterior appearance of a tiger shark is relatively atypical for the family of Carcharhinidae (Grey Sharks).
Fish Hoek Bay in South Africa is a common shark siting location. Sharks gather there for the high concentration of seals. In the past 7 years there have been four shark attacks with two of those being fatal. The authorities in Fish Hoek bay have set up shark spotters which communicate by radio and setup in key spots to spot Great Whites. When a shark is spotted they close the beach and warn of Great Whites in the water.
Great White Sharks are greatly misinterpreted as vicious man-eaters because of the media, movies, and people’s imaginations, but they are actually large fish who mistake people for seals and other marine life. What is a great white shark? The great white, among the least understood of Earth’s creatures, is an apex predator, meaning that it is at the top of the food chain with no natural predators. This means great whites have their pick of food when it comes to selecting their prey (Klimley 15). Carcharodon carcharias, better know as the great white shark, have existed as a group for over 350 million years (Long).
When asked to draw a shark, most people would draw a shape along the lines of the whaler shark family, tigers or a mackeral shark such as a porbeagle. However many people do not realize the sheer diversity in the shape of sharks, or that rays are really sharks. Seldom does such an animal inspire such a variety of emotions reflecting a mixture of fascination, awe and fear. Sharks have occasionally exacted a terrible price from humans who have trespassed on their territory. No better understood than the ocean that they inhabit, these creatures should be regarded in the same way as lions, tigers, and bears: as dangerous, predatory but nonetheless magnificent animals.
What is the largest fish in the world? The answer would be the Rhincodon typus, or commonly 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.
The buffeo is the smallest of all dolphins averaging about 4 feet. The bottlenose is closer to 10 feet. The killer whale, which is also considered a dolphin, can grow to be 30 feet long. The pilot whale is also considered a dolphin. Dolphins were once hunted by commercial boats for the small amount of oil that can be extracted from their body.
