How do sharks hunt? Sharks use their amazing senses to locate fish. Sharks have jaws that are not connected to their heads. They are also very fast so that they can catch their prey.
How does a shark find its food? They use their special senses to hunt and find there food. Sharks have an incredible sense of smell to find their prey. They can smell a drop of blood in an Olympic sized pool. The can also sense electric pulses in the water to locate their prey. Sting rays can also do this. Sharks also have night vision and super hearing. Sharks are kind of like super heros.
We now know how a shark finds its food but how does it catch up to its food to eat it? Sharks don't have bones but they have a flexible tissue called cartilage. Cartilage can also be found in the human body in the ear, nose, and rib cage which is why you can bend your ear in half without it hurting at all. Cartilage makes the shark more flexible so they can move their tail faster to make them faster. Sharks also have different shapes so each type of shark is faster than the other. Sharks use their incredible speed to catch up to there food to eat it.

So how do shark’s jaws work? A shark’s jaw is not connected to its head which lets there mouths open very widely. It's mouth is only held in place by a flexible connective tissue. At the beginning of the attack, the shark raises its snout. Then it lowers its bottom jaw. After, it dislocates its upper jaw which thrusts it upper teeth forward to grab onto its prey. Then the shark’s upper jaw and lower jay connect using brutal force. The shark uses force of up to 699 pound per square
Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
Mojetta wrote about prehistoric sharks, and the history of these creatures. According to Angelo Mojetta, author of Sharks, Cladoselache genus, one of the first prehistoric sharks, was buried in sediment that kept it preserved. Unlike other sharks, Cladoselache genus had a circle of tiny plates around it’s eyes for protection against it’s victim’s attempts to fight back. These sharks lived over 400 million years ago. Sharks of the past could mostly be identified by their teeth, because shark’s bodies are made of cartilage. Another shark that was focused on was called, Stethacanthus. This shark had a very unique look. Stethacanthus had a brush like decoration on the top of it’s head, and an extra fin like part that had the same bristle like decorations on it. These characteristics were thought to be used as suction cups, to hitch rides from larger fish. One of the most famous sharks that looks like an over...
Low oxygen consumption rates were reported in this study, most likely due to the low standard metabolic rates of the nurse sharks. Nurse sharks also had a lower routine metabolic rate compared to other species, which was attributed to their slower swimming speeds. Metabolic rate increased with temperature. The cost of transport was lower than is found in other species. This was attributed to the nurse sharks inactivity and less streamlined body.
The Carcharhinus leucas commonly called the "bull shark" is a very unique shark. The bull shark can live in both salt water and fresh water but is commonly found along the Mississippi River and around Nicaragua. The bull sharks has a very blunt rounded nose giving it a bullish type of appearance thus giving it the name bull shark. The sharks are a dark black to a light grey with a white underbelly. Bull sharks can grow to be about 350 cm long and weigh around 230 kilograms. Bull sharks also tend to have smaller eyes compared to many other sharks which indicates that the bull sharks have limited vision. The bull sharks have triangular teeth like the great white shark (one of the bull sharks cousins). The bulls teeth are heavily serrated and are about 1.5 inches long which makes it easy to tear apart the flesh of their prey.
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...
Their dorsal fin is extremely long, tampered and pointed in a triangular shape or rounded and curved towards the end. The skull is oval shaped and the beak is extremely short and rounded at the end. The killer whale’s jaw is powerful with teeth that are able to tear apart flesh of their prey. They can withstand the jolting, wiggling and hurtling movements of prey that are trying to escape. The killer whale is born with a single blow hole instead of two. Their flippers are paddle shaped with rounded ends and flukes are tapered back and pointed at the end resembling to a triangle/pyramid
It is one of the only times in the year in which the whole of America
In the front of the head is the melon. Its melon transmits sound waves that help it see at night to helping it catch its prey. Killer whales have sharp, cone-shaped teeth made for ripping and tearing prey. The Killer Whale has no sense of smell because there is a part of their brain missing that is missing. The sense of smell goes unused because they spend most of the time in the ocean. The blowhole helps the Killer Whale to breathe; the blowhole flap provides a watertight seal. To open its blowhole, a killer whale relaxes the muscle covering the hole (SeaWorld Parks & Entertainment).
On average they weigh 4,000-7,000 pounds and grow approximately 16-20 feet long ( Great white sharks 1). < commentary needed>Great Whites are the apex predator of the ocean containing 300 serrated teeth and highly-developed senses to hunt prey. Sharks have a great senses of smell, the Great White can smell a drop of blood thousand of miles away. They’re hearing is very powerful , being able to hear the vibrations of prey distances of about 800 ft away and find the exact location through ‘ear stone’( Great white 3). A shark 's sense of hearing truly shows their uniqueness as an apex predator. In addition to great hearing they’re known to have great sight by being able to see up to 50ft away and transition into seeing in light and dark. Additionally sharks have a lateral line on their back that reaches from the front to the back tail, allowing
The Great white sharks sense of smell is better than a human. A great white shark could smell a drop of blood from at least 500 miles away! Their eyesight is not so good but when a great white shark is being attacked they roll their eyes to the back of their heads so they can protect them. Sharks have an ear stone that senses vibration in the water from over 100 miles away. Sharks are great hunters.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
They rest during the daylight in crevices in the corals and from their position they suddenly leap at their un-suspecting prey which could be small fish and crustaceans. The species may also create suction by rapidly opening the mouth to draw the prey in. Scorpion fish are able to stun their prey using their venom. The opportunistic hunting performed by scorpionfish is supported by their camouflage to get close to prey unnoticed before striking rapidly. Also, the big mouth of the species allows –when wide open- to engulf its meal in a big gulp.
The whale shark is a species with a fascinating ecology, life history, behavior, anatomy and physiology. Background The whale shark’s broad, flat head and large mouth make it very recognizable. Females typically grow to be bigger than the males and weigh anywhere from 47,000lbs to 66,000lbs as adults.
