The Great White Shark Great white sharks are thought to be one of the most vicious animals on earth because of how they are represented in movies and television shows. In reality they're really just another animal trying to stay alive. Great white sharks are recognized by the grey skin, white bellies, a bullet shaped build and rows of more than 300 really sharp triangular teeth. Great whites are the largest predatory animals in water in the world.…
Mammals: Description: Mammals are warm-blooded animals so they are able to live in almost any climate in the world. They are a vertebrate, which means they have a backbone or spine. Most live on land and they typically give birth to live young. Description of gas exchange: In mammals gas exchange takes place in the lungs.…
My Intertidal Hero, Hemiscyllium ocellatum - The Epaullet Shark. This extraordinary creature, unlike any other inhabits the shallow tidal reefs or North-Western Australia and New Guinea. {1} It is in my eyes a creature like no other, able to withstand cyclic periods of extreme hypoxia{2} and has developed the ability to walk on land from one tide pool to the next.{3} I believe that this particular Teleost shows adaptive evolution right before our eyes.…
The search continued Tuesday for the missing companion of a young woman killed in a shark attack last week, while news of the UCLA graduate student's violent death stunned classmates and faculty members on the Westwood campus. Members of Roy Jeffrey Stoddard's family were arriving at his Malibu home, still hopeful that he would be found alive, even though it has been more than five days since he set out from Malibu on a short morning kayaking excursion with his girlfriend, Tamara…
The upper teeth grasp the prey while the lower teeth grind the flesh. What makes their teeth truly unusual is that like the Cookiecutter Shark, Greenland Sharks can cut a plug into the flesh of its prey. By swinging its head in a circular motion, it can use its teeth to cut out a chunk. This is extremely useful because Greenland Sharks can feed on prey that is otherwise too large to…
The Blacktip Reef Shark is native to the tropical coral reefs of the Indian and Pacific Oceans. The Blacktip is listed under kingdom animalia, phylum chordata, class Chondrichthyes, order Carcharhiniformes, family Carcharhinidae, and genus Carcharhinus. This shark was given its name based off of the blacktip at the end of its dorsal fin. This fin appears very vivid in the shark’s youth, but fades with age. The Blacktip Reef Shark will most likely grow to be 4.9 feet and weigh roughly 40 pounds, living up to be twelve-years-old.…
The frilled shark It might be time that we humans questioned our relationship with the oceans of the world. Sure, it has been a good few thousand years, but maybe we rushed into our love of the ocean. After all, what do we really know about the deep ocean? It seems as if every other day we are finding out something new and disturbing. The frilled shark is one of the oldest living animal types on the planet.…
They have taste buds in their mouth and the throat so they can identify what they eat. Great white sharks eat seals, sea lions, fish, squid, and even other sharks. Although adults of this species are best known as predators of marine mammals, Great Whites are predominantly fish-eaters throughout their lives but even large individuals will take small prey opportunistically. Highly curious and exploratory, Great White Sharks often investigate novel objects in their environment first visually and, if nothing too frightening occurs, eventually by gentle mouthing a habit which can prove fatal for humans and will scavenge whenever possible. At whale carcasses, this generally solitary species often establishes temporary social hierarchies which are based largely on size.…
The first time I saw Jaws was a life-changing experience. I stopped taking baths (and I don't think I am the only one). So, when I found out about a man who has found (and continues to find) new sharks, I jumped in….to the story, not the ocean.…
Cartilaginous fishes provide a notable example of successful evolutionary perseverance with a fossil record extending to at least the Lower Devonian over 400 million years ago (8). Carcharodon carcharias, also known as White Pointer, White Death, or more commonly, White Shark, is one of the greatest predators in the world among marine life. They are usually found in tropical areas but research has been conducted on these sharks from the Northwest Atlantic to Southern Africa to North East near the Hudson canyon. The average size of a White Shark is 6.4 meters and they weigh on average, 2268 kg. Temperature greatly affects white sharks metabolism, hunting fields, living distribution and mating habits. Unlike some marine life, white sharks are warm blooded (endotherms) and can regulate their body temperature.…
Also sharks have amazing electrical sensitivity, that some organs may lead to better navigation in cars, planes, and ships. In conclusion sharks are very beneficial to…
The Truth About Sharks. Discrimination toward teenagers is one of the most common types of discrimination there is in society. In the story “The Truth About Sharks’ written by Joan Bauer, a teenage girl named Beth is wrongly accused of shoplifting due to her age. On top of simply being a teenager, a teen’s appearance can also bring more discriminatory judgment toward them, as happens to Beth in the story. People who lack a sense of power in their lives tend to take it out on teenagers in the sense that they are an “easy” or “vulnerable” target.…
The great white shark: the king of ocean, the evil ruler, destroying everything in it’s path. From the looks of them, it would be understandable to make this assumption. But let’s clear the air for our good friend, the great white. In fact, over 80% percent of shark attacks had survivors. I mean, they lost a limb maybe, but they survived!…
Sharks have no bones and that ’s one of the reasons that sharks have so many rows of teeth. They have no jawbone so when they try to chomp fish the many teeth help them. Their teeth also have no roots which is another…
Sound is a means of communication by animals. Many fishes are capable of producing sounds with the help of specialized structures. Fish have evolved the largest diversity of sound-producing mechanisms among vertebrates, and sounds are emitted in numerous contexts: e.g. disturbance situations, during courtship, competitive feeding and territorial encounters. Sounds are also produced unintentionally including those made as a by-product of feeding or swimming. The majority of sounds produced by fishes are of low frequency, typically less than 1000 Hz.…
