Their extensive movements are related to reproductive or feeding activities or to seasonal environmental changes. Tagging returns from large sharks on the east coast of the United States indicate regular movements between New Jersey and Florida, and blue sharks have been recovered after crossing the southern Atlantic Ocean.

A tagged spiny dogfish Squalus acanthias was recovered after traveling about 1, km 1, miles in days. Advances in tracking technologies include the use of satellite tags that continuously beam a signal to orbiting satellites whenever the shark surfaces and in that manner reveal north-south movements, transoceanic movements, and roaming and migratory patterns that are beginning to be understood for many species.

Some members of the Carcharhinus genus—most notably the bull shark C. Riverine sharks are small to medium-sized and are exceptionally voracious and bold.

These fins are used for steering during swimming and help to provide the shark with lift. The pelvic fins are located behind the pectoral fins, near the cloaca, and are also stabilizers.

Not all sharks have anal fins , but if they do have them, they are found between the pelvic and caudal fins. The tail region itself consists of the caudal peduncle and the caudal fin.

The caudal peduncle sometimes has notches known as "precaudal pits", which are found just ahead of the caudal fin.

The peduncle may also be horizontally flattened into lateral keels. The caudal fin has both, an upper lobe, and a lower lobe, that can be of different sizes and the shape depends of which species the shark is.

The primary use of the caudal fin is to provide a "push" while the shark swims. The upper lobe of the caudal fin produces the most amount of the push, and usually forces the shark downwards.

The pectoral fins and the shape of the body like an airfoil work together to counter this force. The strong, non-lunate caudal fin in most benthic shark species allows the shark to swim close to the seabed such as the Nurse shark.

However, the fastest swimming sharks such as the Mako sharks tend to have lunate-shaped crescent-shaped caudal fins.

Sharks have keen olfactory sense organs in the short duct between the front and back nasal openings. They can detect blood from miles away: as little as one part per million of blood in sea water may be enough.

Sharks have the ability to determine the direction of a given scent based on the timing of scent detection in each nostril.

They are more attracted to the chemicals found in the intestines of many species, and as a result often linger near or in sewage outfalls.

Some species, such as nurse sharks , have external barbels that greatly increase their ability to sense prey. Shark eyes are similar to the eyes of other vertebrates , including similar lenses , corneas and retinas.

Their eyesight is well adapted to the marine environment. They can contract and dilate their pupils , like humans, something no teleost fish can do.

A tissue behind the retina reflects light back, thereby increasing sight in darker waters. Sharks have tiny holes all over the shark's snout, especially between the eye and the tip of the snout.

In them are nerve receptors which are called the ampullae of Lorenzini. Animal in the water give off electricity: every time an animal's heart beats or it moves, tiny currents of electricity are made.

These tiny electric currents make signals that travel through water and get sensed. Sharks may use this sense when they catch their prey, even more than they use their sight.

Although it is hard to test sharks' hearing, they may have a sharp sense of hearing and can possibly hear prey many miles away. The lateral line detects changes in water pressure.

It is open to the environment by a line of pores. This and the sound-detecting organs are grouped together as the 'acoustico-lateralis system', because they have a common origin.

In bony fish and tetrapods the external opening into the inner ear has been lost. This system is found in other fish as well. It detects motion or vibrations in water.

Just a few million years ago, a giant shark called Megalodon swam in the seas. It was 18 meters long, twice as long as the closely-related great white shark, and it ate whales.

Megalodon died out 1. Much of what we understand about prehistoric sharks comes from the study of their fossils. While sharks have skeletons made of soft cartilage that can fall apart before fossilizing, their teeth are harder and easily fossilized.

Prehistoric sharks, like their modern descendants, would grow and shed many thousands of teeth over their lifetime. For this reason shark teeth are one of the most common fossils.

Sharks have skin covered in millions of tiny teeth-like scales that point to the tail. If you rub along a shark towards the tail, it would feel smooth, but if you rub the other way, it would be rough.

Sharks' teeth can be 20 times as big as human teeth and they can grow back if they are lost. The fins of sharks are used for stabilizing, steering, lift and swimming.

Each fin is used in a different manner. There are one or two fins present along the dorsal midline called the first and second dorsal fin. These fins help the shark from constantly rolling around.

These two fins may, or may not have spines. When spines are present, they are used for defensive purposes, and may also have skin glands with them that produce an irritating substance.

The pectoral fins are located behind the head and extend outwards. These fins are used for steering during swimming and help to provide the shark with lift.

The pelvic fins are located behind the pectoral fins, near the cloaca, and are also stabilizers. Not all sharks have anal fins , but if they do have them, they are found between the pelvic and caudal fins.

Prehistoric sharks, like their modern descendants, would grow and shed many thousands of teeth over their lifetime. For this reason shark teeth are one of the most common fossils.

Pups are born with a full set of teeth, and are capable of taking care of themselves. Once born, they quickly swim away from their mothers, who sometimes feed on the pups.

Litters vary from one or two pups great white shark to one hundred pups blue shark and whale shark. Some sharks are oviparous , laying their eggs in the water.

Shark eggs sometimes called "mermaid's purses" are covered by a tough, leathery membrane. Most sharks are ovoviviparous , meaning the eggs hatch inside the female's body, with the babies developing within the mother, but there is no placenta to nourish the pups.

Instead the young feed on the egg's yolk. The pups eat any unfertilized eggs and sometimes each other. Very few pups in a litter survive until birth due to this form of sibling cannibalism.

Great white sharks , mako sharks , nurse sharks , tiger sharks , and sand tiger sharks reproduce this way. Some sharks are viviparous , meaning that the females give live birth: the eggs hatch inside the female's body, and the babies are fed by a placenta.

The placenta helps transfer nutrients and oxygen from the mother's bloodstream and transfers waste products from the baby to the mother for elimination.
