Great White Shark Ocean Life

The Australian Grey Nurse Shark is also known as the Spotted Ragged-Tooth Shark and as the Sand Tiger Shark ("Australian Threatened Species”). The species is identified by its gray to gray-brown coloration, the possible presence of reddish/brownish spots on the caudal fin and posterior half, their countershading, and by its two almost equally sized dorsal fins. They are known to grow over 3.6 meters in length with the males and females maturing at different lengths, 2.21 meters and 2.2 meters, respectively (McGrouther, 2015). Females also mature significantly later at 9-10 years than their male counterparts, who mature at 6-7 years. Their diet consists of fish,

The Great White Shark is the top predator of the ocean, meaning that it is not hunted by other animals in the waters. The Great White has been listed as an endangered species due to the over hunting of them for shark teeth and there fins.

They are usually found in the Northern Pacific Ocean, ranging as far south as the Sea of Japan and as far north as the Bering straight. It’s believed these sharks spend a majority of their time in epipelagic waters, but individuals have been observed in waters as deep as 660 meters. Salmon sharks are generally about 200-260 centimeters long and weigh around 220 kilograms. They are usually medium grey to black in color with a white underbelly and short, cone-shaped snouts. Overall they have a great resemblance to Great White sharks, hence the nickname “Mini Great Whites”. The primary prey for these sharks is salmon, but they also eat squid, herring, and pollock. Salmon shark are also ovoviviparous, with a litter size of 4-5

The largest ever recorded was 79 inches. It has narrow upper and lower teeth. Male adults commonly have sharper teeth than females. They have about 28 teeth in the upper jaw and 27 in the lower jaw. They are beige or brown in color on the dorsal fin and white on the belly. Each of its fins have black tips at the end of them which is where it gets its name. The black tip reef shark mainly eats small fish such as mullet and invertebrates such as shrimp.

White sharks are usually found in oceans worldwide. They tend to appear more in cool temperate and tropical waters. Also, some are usually found near islands with high populations of seals. They spread throughout the world. Some of the places they are found in are along the coastline of South Africa, Australia, New Zealand, California to Alaska, Hawaii, the Mediterranean Sea and many more.

The blacktip sharks can live worldwide in different oceans. Unlike a great white shark that like to live in cooler water or unlike a greenland shark that lives only in greenland, a blacktip sharks lives Atlantic ocean,Indian ocean,and both Western and Eastern Pacific. Because of living in different places fishers catch blacktip shark for their fins to sell with a high piece. It is a con and pro for the blacktip sharks to live worldwide

An international team of Scientists have discovered a new lineage of extinct plankton feeding sharks called pseudomegachasma. These sharks are said to have inhabited the warm oceans of nearly 100 million years ago. From data of newly collected fossil teeth, it is found that this new lineage of extinct sharks is very similar to the modern-day plankton eating megamouth shark. Lead Author professor Kenshu Shimada also states that these sharks would have evolved independent of the four known modern-day planktivorous cartilaginous fishes. These consist of the megamouth shark, basking shark, whale sharks, and manta rays. This discovery of the new lineage of extinct vertebrates is what makes this article completely relevant to the topic of week fourteen.

the great white shark has a lot of similar attributes to a whale. a whale has a very strong big tail that can push them anywhere in the ocean, similarly to the great white. the great white also has a very thick layer of skin which can protect and keep them warm though all the seasons. unlike the sword fish or the blue fin tuna, the shark and whale species tend to stay lower in the deeper parts of the ocean. they also are similar in that they dont go out looking for food most times. most the time they see the food as they are moving about so they go for it or the prey cant escape. the whale is a lot different from a great white shark. any whale can be up to ten times the size! in saying that, if the whale really wanted to it could totally

Great white sharks live in almost all coastal and offshore waters which have water temperature between 12 and 24 °C (54 and 75 °F).Great white shark off Guadalupe Island, Mexico.The Great White Shark can be found in water as three feet deep, and as deep as 1280 metres.

The list of The Unique and Sizable Facts about Sharks: Sharks have Seven Senses Every animal has unique features in hunting for prey to survive, and sharks seem to have seven sharp sense in hunting for its preys. Researchers said that sharks can see under the dark waters with their night vision similar to cats and they have an excellent sense of smell which is 10,000 greater than humans have. Sharks are also excellent in hearing in detecting wounded preys and hunt them with their great sense of smell that can decipher whether it is their mate or predator by analyzing smells in the shark’s brain. The shark also has other features which are pressure-sensitive teeth, sense of feeling vibrations as signals and detecting changes in temperature and currents of the water.

Great white sharks (Carcharodon carcharias) are very fascinating creatures. Did you know their skeleton is completely made of cartilage? Great whites have a blue-grey dorsal which helps them blend in with the ocean when being viewed. They also have a white belly which makes it difficult to view them from below because of the blinding sunlight from above. Can you believe that great whites average 15 feet in length and can weigh up to 5,000 pounds? They have

These apex predators fall under the classification class Chondrichthyes, which is comprised of cartilaginous skeleton. Chondrichthyes is sub-divided into two classes; the Elasmobranchii, composed of sharks, skates and rays, and the Holocephali (“Shark Taxonomy” 8). As we move further down the scientific classification, identifying these similar looking creatures become more difficult. Their order is separated into two super-orders, which are the extinct Cladoselachimorph and the Euselachii; composed of 12 orders of which only nine are amongst us today (9). Many scientists believe that sharks descended from an eyeless, finless, and boneless leaf shaped fish and that they came to existence at around 400 million years ago (“Shark Evolution” 1). Documented fossil records show that there were over 3,000 types of sharks and may have existed at the same period of time (Jones, “The Epic History of Sharks”). The reason it is difficult to discover them all is due to the rotting of the cartilaginous bone structure (“Shark

A shark has multiple rows of teeth. The mouth of sharks is in the front of the head. In some species, sharks teeth are replaced as much as once a week. Some sharks have teeth used to crush and grind. These are some what like what humans have. They also have sharp teeth. These can be compared to incisors that humans have. These types of teeth are very important to sharks because they are carnivores and depend on their teeth in order to eat their prey. A sharks body in covered by scales which cover their bodies. These scales make the skin of a shark very rough and strong.

Sharks have been in our oceans for almost 450 million years. Those millions of years of evolution have allowed many different shark species to develop abilities, and to become perfect predators.

jaw structure. The teeth are actually modified, enlarged placoid scales. The teeth aren’t anchored in the jaw; they are just embedded on the gums. Unfortunately, when the great white shark eats on its prey, it sometimes loses or breaks the tooth by the flesh. Luckily, sharks have developed a special feature that enables it to replace its missing tooth. They have developed rows of teeth, each tooth moving up to replace the missing one. A whole broken row of teeth can be replenished, just like a conveyor belt. Each tooth, though, has a different shape, changing according to its necessity. The great white has triangular, serrated-edged teeth anywhere from one to two inches long. With this feature, the shark is able to tear through the flesh for its meal. The jaw of the shark is made up of strong bone tissue. It must be very powerful because the shark is designed for feeding.
