An approximate number isn't available on the populations of Bull sharks as they are found all over the world and are hard to keep a track of.
Where does a Bull Shark live?
Bull sharks live in shallow coastal waters and in depths ranging from 1-150 m, and they are often found in estuaries, harbors, lagoons, and river mouths all over the globe.
What is a Bull Shark's habitat?
Bull sharks are known to have a vast habitat because of their ability to survive in freshwater as well as saltwater. They are found alongside coastal areas. Bull sharks have found their way into the local vocabulary of humans because they can be found almost all over the world.

How do they reproduce?
Male Bull sharks reach sexual maturity at the age of 15 years, while females reach sexual maturity at 18 years of age. Being mammals, female bull sharks give birth to live pups in freshwater in order to protect them from the dangerous environment of the seas and oceans after an 11 month gestation period. These juvenile Bull sharks enter estuaries with low salinity marine waters and use them as nursery grounds to develop.
What is their conservation status?

Bull Shark Fun Facts
What do Bull Shark look like?
Bull sharks have a thick, stout body with a long pectoral fin with a blunt snout. Bull sharks have a gray coat on top and are white below. Younger bull sharks can be differentiated by their dark-tipped fins.

How do they communicate?
Bull sharks and all other species of sharks communicate with one another by arching their bodies visually. Sharks use a special organ named 'lateral line' which helps them feel vibrations in the water, helping them navigate marine waters. They are also known to use this sense to locate prey by detecting blood and finding mates.
How big is a Bull Shark?
Bull shark size varies from male to female sexes. Female bull sharks are larger than males in comparison. At birth, a bull shark pup weighs around 6.6 lb (3 kg) and is 23.6-27.9 in (60-71 cm) long. An immature female has an average length of 74.4 in (189 cm) and an immature male is around 76 in (193 cm). Both have similar weights at around 116.8-119.1 lb (53-54 kg). At adulthood (age 18), females can weigh up to 244.7 lb (111 kg) and can grow up to 131.9 in (335 cm). Whereas males on reaching adulthood at the age of 14, weigh around 209 lb (95 kg) and are 89.8 in (228 cm) long.
The sizes of adults vary in geographical regions. North American Bull sharks are larger than those found in Costa Rica and other regions. The largest female Bull shark ever found in Costa Rica was measured at around 98.8 in (251 cm) and the largest male was around 94.9 in (241 cm) long.
How fast can a Bull Shark swim?
Like all other sharks, Bull sharks are agile in the water which makes them dangerous as a predator. These sea creatures can swim at a maximum speed of 25 mph (40.2 km/h)!

Unlike other animals, sharks do not have specific names assigned to their male and female counterparts.
What would you call a baby Bull Shark?
A baby Bull shark is called a pup. They are laid by the females in flat areas along the shore of coastal areas to protect them from predators and to help them thrive in nature.
What do they eat?
Bull sharks eat small sharks, bony fish, other bull sharks, and stingrays. In other instances, their diets include sea turtles, crustaceans, birds, and dolphins. The feeding ground for Bull sharks is located mostly in murky water systems where they attack prey that include sea turtles and other fishes. The murky water helps them to camouflage with their surroundings.
Are they dangerous?
Bull sharks are obviously at the top of the food chain because of their aggressive nature, making them apex predators. Bull shark bites have been recorded as the strongest bite of any other shark bites that have been studied. They are notorious as most shark attacks on humans are by Bull sharks because of their close proximity to the human population, especially in coastal areas. We are much more likely to get attacked by Bull sharks than Great White sharks or Tiger sharks.
Would they make a good pet?
Bull sharks are apex predators and are hostile and unfriendly to everything around them, which makes them savage, and outright deadly. They are unsuitable to be kept as pets since more human deaths come at the jaws of Bull sharks than any other shark species.
Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.
But unlike Great White sharks, they can live in captivity. It has been recorded that the oldest Bull shark in captivity, has lived up to 30 years. The Oklahoma Aquarium in North America houses 10 Bull sharks in a 500000-gallon tank.
Did you know...
Bull sharks are more likely to come into contact with the human population as they are the only sharks to be able to live in freshwaters. They are known to migrate from saltwater to freshwaters. They can be found upriver in the Amazon river basins, Mississippi River, and Lake Nicaragua. Because of their ability to thrive in freshwater and saltwater, they have a wide range of habitats. With that, they have been a part of the local legends, and they have been given names like the Zambezi shark in Africa, Lake Nicaragua shark in Nicaragua, freshwater whaler, estuary whaler, swan river whaler, shovelnose shark, cub shark, van Rooyen's shark, Fitzroy Creek Whaler and Ganges river shark (Glyphis gangeticus).
Fun fact, there's a shark-infested golf course in Brisbane, Australia! The Carbrook Golf Club near Brisbane is situated next to the Logan River, and because of floods, some Bull shark pups were stranded in the lake, and have been living there ever since.
Bull shark fin is eaten as a delicacy in countries like Japan and Australia.
How long is a Bull Shark?
Female Bull sharks can grow up to 131.9 in (335 cm) and males can grow up to 84 in (213.4 cm).
Differences and similarities with other common fish
Bull sharks are easily able to adapt to freshwater bodies, which allows them to have an unusual migratory pattern where they give birth in freshwater bodies, unlike other species of sharks. While stout, like most other fishes, the Bull shark has a streamlined body starting from its head, something we do not see with the Hammerhead shark.
