10. Lemon Shark

The lemon shark, Negaprion brevirostris, is a shark belonging to the family Carcharhinidae that can grow 10 feet (3.0 m) long. The lemon shark is found mainly along the subtropical and tropical parts of the Atlantic coast of North and South America, and around Pacific Islands.

The longest lemon shark recorded was 13 ft long, but they are usually 8 to 10 ft (3.0 m). They like tropical water, and like to stay at moderate depths. Lemon sharks are often accompanied by Remoras.


9. Blue Shark

The blue shark, Prionace glauca, is a carcharhinid shark which is found in the deep waters of the world’s temperate and tropical oceans. They prefer cooler waters and are not found, for example, in the Yellow Sea or in the Red Sea. Blue sharks are known to migrate long distances, from New England to South America for example. Although generally lethargic, they are capable of moving very quickly if the need arises. Blue sharks are viviparous and are noted for their large litters of 25 to over 100 pups.

They feed primarily on small fish and squid, although they are perfectly capable of taking larger prey should the opportunity present itself. They are often found in schools segregated by sex and size, and this behavior has led to their being nicknamed the “wolves of the sea”.

8. Hammerhead

The hammerhead sharks are a group of sharks in the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a “hammer” shape called a “cephalofoil”. Most hammerhead species are placed in the genus Sphyrna; some authorities place the winghead shark in its own genus, Eusphyra.

Many, not necessarily mutually exclusive, functions have been proposed for the cephalofoil, including sensory reception, maneuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves.

7. Sand Tiger Shark

The grey nurse shark (Australia), spotted ragged-tooth shark (Africa) or sand tiger shark (US and UK), Carcharias taurus, is a large shark inhabiting coastal waters worldwide, with many different names in different countries in the world. Despite a fearsome appearance and strong swimming abilities, it is a relatively placid and slow moving animal. It is considered not aggressive unless provoked.

The body is stout, with two large dorsal fins and the tail is elongated and has a long upper lobe. The shark has a precaudal pit but no caudal keels. It grows to a length of 3.2 m (about 10.5 ft). Male grey nurse sharks mature at 2.1 m (about 6′ 11″); and females mature at 2.2 m (about 7′ 3″). This shark weighs 90 to 160 kg (200 to 350 lb).

6. Grey Reef Shark

The grey reef shark (Carcharhinus amblyrhynchos, sometimes misspelled amblyrhynchus or amblyrhinchos) is a species of requiem shark, family Carcharhinidae. One of the most common reef sharks in the Indo-Pacific, it is found as far east as Easter Island and as far west as South Africa. This species is most often seen in shallow water near the drop-offs of coral reefs.

The grey reef shark has the typical “reef shark” shape, with a broad, round snout and large eyes. This species can be distinguished from similar species by the plain or white-tipped first dorsal fin, the dark tips on the other fins, the broad black rear margin on the tail fin, and the lack of a ridge between the dorsal fins. Most individuals are less than 1.9 m (6.2 ft) long. 

Grey reef sharks are fast-swimming, agile predators that feed primarily on free-swimming bony fishes and cephalopods. Their aggressive demeanor enables them to dominate many other shark species on the reef, despite their moderate size. Many grey reef sharks have a home range on a specific area of the reef, to which they continually return.

5. Shortfin Mako

The shortfin mako shark, Isurus oxyrinchus (“sharp nose”), is a large mackerel shark. Along with the closely related longfin mako (Isurus paucus) it is commonly referred to as “mako shark”. The shortfin mako’s speed has been recorded at 50 km/h (31 mph), and there are reports that it can achieve bursts of up to 74 km/h (46 mph). It can jump up to 9 m (28 ft.) in the air. Due to its speed and agility, this high-leaping fish is sought as game worldwide. This shark is highly migratory. Its endothermic constitution partly accounts for its relatively great speed. The shortfin mako has a formidable and foreboding appearance.

The ISAF statistics on attacking species of sharks purports that between 1580 and 2007, the shortfin mako has had eight recorded unprovoked attacks on humans with two ending in fatality and twenty boat attacks. In New Zealand Mako sharks are often encountered in the waters of the North Island. Sharks can be attracted to caught fish with accounts of spear fishermen being approached by curious sharks and even being “slapped” with cavitation bubbles from a swift tail flick.

4. Ocean White Tip

The oceanic whitetip shark, Carcharhinus longimanus, is a large pelagic shark inhabiting tropical and warm temperate seas. Its stocky body is most notable for its long, white-tipped, rounded fins.  This aggressive but slow-moving fish dominates feeding frenzies, and is a danger to shipwreck or air crash survivors—it has attacked more humans than all other shark species combined.

The whitetip poses a minimal threat to bathers or inshore sportsman, but a high risk for humans caught in the open ocean. Although the whitetip is opportunistic and aggressive, and may attack humans for food, divers have swum with this shark repeatedly without incident.

Divers are advised to approach the shark only with extreme caution, to not spear fish near this shark and, if the shark comes too close or gets too inquisitive, to get out of the water as soon as possible.

3. Tiger Shark

The tiger shark, Galeocerdo cuvier is a species of requiem shark and the only member of the genus Galeocerdo. Mature sharks average 3.25 to 4.25 metres (10.7 to 13.9 ft) long and weigh 385 to 635 kilograms (850 to 1,400 lb). It can attain a length of over 5 metres (16 ft) and a weight of 1,110 kilograms (2,400 lb) at maximum. It is found in many tropical and temperate oceans, and is especially common around central Pacific islands.

This shark is a solitary, mostly night-time hunter. Its name derives from the dark stripes down its body, which fade as the shark matures. Although shark attacks are a relatively rare phenomenon, the tiger is responsible for a large percentage of fatal attacks, and is regarded as one of the most dangerous species.

Tiger sharks are often found in river estuaries and harbours, as well as shallow water close to shore, where they are bound to encounter humans. Tiger sharks also dwell in river mouths and other runoff-rich water.

2. Great White Shark

The great white shark, Carcharodon carcharias, also known as great white, white pointer, white shark, or white death, is a large lamniform shark found in coastal surface waters in all major oceans. The great white shark is very well known for its size, because it can exceed 6 metres (20 ft) in length and 2,240 kilograms (4,940 lb) in weight. It becomes sexually mature at around 15 years of age and has a lifespan of 30 to over 100 years.

The great white shark is arguably the world’s largest known predatory fish, eating dolphins, porpoises, whale carcasses and pinnipeds such as seals, fur seals and sea lions. It is the only surviving species of its genus, Carcharodon. While great white sharks have killed a few humans, they typically do not target them: for example, in the Mediterranean Sea there have been 31 confirmed attacks against humans in the last two centuries, most non-fatal. Many incidents seem to be “test-bites”. Great white sharks also test-bite buoys, flotsam, and other unfamiliar objects, and might grab a human or a surfboard to identify it.

1. Bull Shark

The bull shark, Carcharhinus leucas, also known as the whaler shark, Zambezi shark or unofficially known as Zambi in Africa and Nicaragua shark in Nicaragua, is a shark common worldwide in warm, shallow waters along coasts and in rivers. The bull shark is well known for its unpredictable, often aggressive behavior.

Since bull sharks often dwell in shallow waters, they may be more dangerous to humans than any other species of shark and, along with tiger sharks and great white sharks, are among the three shark species most likely to attack humans.

The bull shark is responsible for attacks around the Sydney Harbour inlets. Most of these attacks were previously thought to be great whites. In India bull sharks swim up the Ganges River and have attacked people. It also eats human corpses that the local population float on the river. Many of these attacks have been wrongly blamed on the Ganges shark, Glyphis gangeticus,[citation needed]a fairly rare species that is probably the only other shark that can live comfortably in both saltwater and freshwater.
