COOKIECUTTER SHARK

The cookiecutter shark (Isistius brasiliensis), also called the cigar shark, is a species of small dogfish shark in the family Dalatiidae. This shark occurs in warm, oceanic waters worldwide, particularly near islands, and has been recorded from as deep as 3.7 km (2.3 mi). It migrates vertically up to 3 km (1.9 mi) every day, approaching the surface at dusk and descending with the dawn. Reaching only 42–56 cm (17–22 in) in length, the cookiecutter shark has a long, cylindrical body with a short, blunt snout, large eyes, two tiny spineless dorsal fins, and a large caudal fin.

Aggressive Or All about COMBAT!

Tiger shark or hammerhead shark one of the two species you defiantly want to stay away from.

                                              Tiger Shark
The tiger shark is one of the worlds most dangerous shark.Who would want to be in the water with a animal blood thirsty.The Tiger shark is all about combat, it was born to battle.The Tiger shark can lock it's jaw and sense fear.The good thing about it is that reproduction periods are only in march and may so if your in tropical places like Florida at that time stay out of the water.Fisherman also like to hunt Tiger shark, they think it's a prize catch. A cool little fun fact is that the Tiger sharks scientific name is  galeocerdo curvier, trust me I had a hard time saying that to :D.

                                                      Hammerhead shark
The hammerhead shark has a aggressive behavior but It's a great hunter.This rectangle head prefers to hunt at night.I can think of three good reasons why it prefers to hunt at night but i'll just get back to some other facts.Found at average depths of around 350 meters.Again I think of three more good reasons.Lets get back to why your really here.Eats all kind of fish even it's own offspring's know wounder they run away as soon as there born. 

                                                                      
                                 Look at the facts V

Eats many fish keeping them from over migrating	attacks are most likely	Found in tropical waters only	Positives grow up to 20 feet
32 km per hour	Their sometimes camouflaged	eats all kinds of fish	Often seen in mass summer migrations
coastal waters	teeth are replaced throughout life	hunts mostly at night	swims at 25 miles per hour
grow slowly		small mouth	can make very sudden sharp turns
		attacking humans is only 3 out of 9

Thresher Shark

The Thresher shark has the biggest tail of any modern day sharks it's tail is 50 percent of the whole body length.It has a short snout and large eye's placed foward on the head.The second dorsal fin is way smaller than the first.The Thresher Shark is a strong swimmer and can leap clear of the water.The jaws are small with small curved sharp teeth.colors veries from black to brown with metallic hues from above and irregular white markings on the underside.

Diet 

 The thresher shark eats schooling fish, such as herring and mackerel and cephalopods such as squid. The large caudal fin is used to slap the surface of the water forcing fish to form tighter schools; the tail can then be used as a whip to stun or kill the prey.

Habitat

  The thresher often swims at the surface of coastal waters. However it can also occur at depths of 350 meters (1,150 feet) or more. The young may be found inshore in shallow water.

Range 

 The Thresher shark is a summer visitor to the Canadian Atlantic region. They have been captured from July to November, but most frequently during August and September. The Thresher ranges through all warm and temperate areas of the worlds oceans. Its northern most range in the western Atlantic is eastern New foundland and it ranges all the way down the Atlantic to the West Indies and northern South America.

white tip reef shark

Triaenodon obesus, derives its name from the distinct white tips on the sharks first dorsal and upper caudal fins. Sometimes the other fins have white tips as well. The body of a Whitetip Reef Shark has a dark brown or greyish color, which fades to lighter colors towards the ventral surface. Some individuals have small dark spots over the entire body. The maximum length of the Whitetip Reef Shark is slightly below 7 feet (2.13 m), but the average length is no more than 5.25 feet (1.6 m). The Whitetip Reef Shark can live for more than 25 years.

The Whitetip Reef Shark feed on chiefly on lobsters, crabs and octopus. It is a nocturnal hunter that feed on bottom living animals that live in crevices and caves. The Whitetip Reef Sharks can hunt prey in very small spaces, since they have a blunt snout and are slenderly built. Their skin is tough and the eyes are protected by ridges. The Whitetip Reef Shark also likes to eat bony fish, such as snapper, triggerfish, eel, squirrelfish, surgeonfish, damselfish and parrotfish.

Since the Whitetip Reef Shark is peaceful and has small teeth is not really a threat to humans unless it is attacked. It will usually avoid venturing to close to swimmers and divers, but can be attracted by food. Some scuba divers hand feed Whitetip Reef Sharks, and accidents can naturally occur during such circumstances when the Whitetip Reef Shark becomes excited and accidentally bites the fingers of the scuba diver. Spear fishing can also attract Whitetip Reef Sharks.

The female Whitetip Reef Shark gives birth to live pups after a gestation period of roughly 5 months. A litter will typically consist of 1-5 pups, and each pup will be 50-60 cm (20-23.6 inches). Mating will occur during varying seasons of the year depending of which region the Whitetip Reef Shark inhabits. The male Whitetip Reef Shark will lie very close to the female, and hold her pectoral fins in his mouth. The male inserts one of his claspers into the genital opening of the female and fertilizes her eggs.

blue shark

Blue sharks are among the most abundant and far-ranging of all sharks, found in tropical, subtropical and temperate waters of every ocean. They are known to migrate long distances, and prey primarily on schooling fish such as anchovies, sardines, herring and squid. Blue sharks will, however, attack virtually anything, including gill-netted salmon and wounded marine mammals. Blue sharks were identified and named by Linnaeus, the father of modern taxonomy, in 1758, and its common name comes from its dark blue dorsal fin and bright blue sides. Adult blue sharks weigh between 70 to 120 pounds and can grow up to five to seven feet long. They are fished commercially, usually on baited long lines, and by sports fishermen with rods and reels.
Blue shark's diet
Squids are a important meal plan for the blue shark.Other meal plans are cuttlefish pelagic octopuses,

Whale shark

As the largest fish in the sea, reaching lengths of 40 feet (12 meters) or more, whale sharks have an enormous menu from which to choose. Fortunately for most sea-dweller sand us!Their favorite meal is plankton. They scoop these tiny plants and animals up, along with any small fish that happen to be around, with their colossal gaping mouths while swimming close to the water's surface.
The whale shark, like the world's second largest fish, the basking shark, is a filter feeder. In order to eat, the beast juts out its formidably sized jaws and passively filters everything in its pathThe mechanism is theorized to be a technique called “cross-flow filtration,” similar to some bony fish and baleen whales.
The whale shark's flattened head sports a blunt snout above its mouth with short barbels protruding from its nostrils. Its back and sides are gray to brown with white spots among pale vertical and horizontal stripes, and its belly is white. Its two dorsal fins are set rearward on its body, which ends in a large dual-lobbed caudal fin (or tail).
Preferring warm waters, whale sharks populate all tropical seas. They are known to migrate every spring to the continental shelf of the central west coast of Australia. The coral spawning of the area's Ningaloo Reef provides the whale shark with an abundant supply of plankton.
Although massive, whale sharks are docile fish and sometimes allow swimmers to hitch a ride. They are currently listed as a vulnerable species; however, they continue to be hunted in parts of Asia, such as the Philippines.
