Bull Shark | Carcharhinus leucas

“Bull sharks are aggressive, common, and usually live near high-population areas like tropical shorelines. They are not bothered by brackish and freshwater, and even venture far inland via rivers and tributaries. Because of these characteristics, many experts consider bull sharks to be the most dangerous sharks in the world.”   -

Blacktip Sharks | Carcharhinus limbatus

“Blacktip sharks are sometimes spotted above the water. They leap above the surface, rotate several times, and splash down on their backs. This dramatic display is sometimes part of a stealthy feeding method they use to strike at schools of bony fishes near the water surface. The sharks hurl themselves at the fish from below. Blacktip sharks supplement their diets with skates, stingrays, squids, and some crustaceans. These sharks have also been known to follow fishing boats and feed on discarded bycatch. 
In 2008 DNA evidence confirmed that a female shark fertilized her own egg, impregnating herself without the help of a male. It’s not entirely known how rare this event, called parthenogenesis, is among blacktip or other sharks.”  -

Megamouth Shark | Megachasma pelagios

"The megamouth shark is considered to be one of the most rare forms of sharks out there. They aren’t often seen by people and that can lead one to wonder if they have decent numbers or not. Only 54 of them have been seen and documented with only 3 of them captured on film.
They weren’t discovered until 1975 when a navy ship accidentally found one caught up in their anchor. Yet it wasn’t until 1983 that it was proven to actually exist. In fact, since the early sighting it was rumored to be just a hoax by the military in an effort to gain attention.
The future of the megamouth shark remains mystifying. Since we don’t really know how many of them exist it is extremely difficult to calculate how many of them there are. Scientists believe they have healthy numbers though and that they are quite versatile so they can easily survive. More research has to be done but finding these sharks can prove to be difficult.” -

Frilled Shark | Chlamydoselachus anguineus

"Because the frilled shark bears such a striking resemblance to an eel, ichthyologists once assumed it navigated the water by wriggling. Now it’s known that this species possesses an oil- and hydrocarbon-packed liver that enable it to float and hover at depths between 160 and 660 feet. Although no one has ever observed the shark hunting, scientists theorize that the frilled shark strikes suddenly at its prey, more similar to a snake than an eel attack. It’s also believed that the shark feeds in caves and crevices on continental slopes, perhaps explaining its thin and narrow physique.
Many sharks undergo long gestation periods, but the frilled shark could actually break the world’s record. Although research on this matter is still ongoing, scientists suspect frilled sharks could gestate for up to three and a half years. An average litter consists of six pups, many of which may not survive into adulthood; thus reproduction in the shark’s deep-sea habitat is slow at best. Since temperatures are also colder at such levels, its metabolic cycle is thought to be equally sluggish.”   -

Tiger Shark | Galeocerdo cuvier

“These large, blunt-nosed predators have a duly earned reputation as man-eaters. They are second only to great whites in attacking people. But because they have a near completely undiscerning palate, they are not likely to swim away after biting a human, as great whites frequently do.
They are consummate scavengers, with excellent senses of sight and smell and a nearly limitless menu of diet items. They have sharp, highly serrated teeth and powerful jaws that allow them to crack the shells of sea turtles and clams. The stomach contents of captured tiger sharks have included stingrays, sea snakes, seals, birds, squids, and even license plates and old tires.”  -

Wobbegong Shark | Orectolobidae

“Wobbegong are highly patterned, flat sharks that can easily hide among the sea floor. They have an powerful jaw and will bite if provoked. These sharks use their bottoms fins to climb around, even sometimes out of the water.”   -

Port Jackson Shark | Heterodontus portusjacksoni

“Blending into their rocky home, Port Jackson sharks have dark markings that run from their blunt head right down the back of their brown-grey body. With a venomous spine in front of their top two fins, this remarkable species is provided with protection from predators attacking from above. Although they are a shark, growing up to around 1.65 metres in length, they are considered to be harmless to humans.”  -
