They give birth to live young every two years in late spring and summer. Although, in warmer places this may take place year-round. After a gestation period of 10-11 months, pup’s are born fully independent at 56-81cm long. Litter sizes can range from 1-13, but are usually between 6 and 8. Habegger, M. L.; Motta, P. J.; Huber, D.

Being able to live in seawater and freshwater is actually very impressive, and bull sharks do it by controlling how much salt is in their wee. In freshwater, bull sharks do really watery wees, whilst in seawater their wee is salty. They do this to keep the perfect amount of salt in their bodies, no matter how salty the water around them is. It's hard work on their kidneys, but opens up lots of freshwater feeding grounds - so probably worth it. 8. Sharks are really, really old Juvenile bull sharks are born in more freshwater environments and as they get older move to more saltwater conditions.

It hunts only in murky waters and compensates its limited sense of sight with a keen sense of smell. If they find a suitable prey, they swim directly toward it reaching speeds of up to 19 kilometers per hour; it hits the victim, and then sink their sharp teeth into the flesh. The rest is already known. REPRODUCTIVE HABITS These sharks prefer hunting in shallow waters that are close to the coast. Most bull sharks reside in waters less than 100 ft. deep. They live in warm waters, and can travel from the ocean into rivers and lakes. Whether you’ve submitted one eggcase or thousands, every eggcase adds to the Great Eggcase Hunt database and helps us to gain a better understanding of egg-laying sharks, skates and chimaera. Bull sharks are believed to be one of the most aggressive sharks on the planet, alongside great white sharks and tiger sharks. The bull shark shares numerous similarities with river sharks of the genus Glyphis, and other species in the genus Carcharhinus, but its phylogeny has not been cleared yet.

Threats to Survival

A taste of freedom! Nine-year-old hostage enjoys first meal of schnitzel and mash and ice cream with his pals before the Israeli football team visit him in hospital to welcome him home after 49 days When it comes to male and female bull sharks the females are larger. Females averaging 2.4 metres have been observed, where males on average have been seen up to 2.2 metres. There have been sightings of bull sharks reaching over 3 metres, however this is rarer.

The Shark Trust is a charity registered in the United Kingdom. And so our terms are governed by the appropriate laws in the United Kingdom. Bull shark longevity appears to be related to geographic region. Studies of bull sharks in the southern Gulf of Mexico indicate that they can reach an age of 28 years for females and 23 years for males. In the northern Gulf researchers found that female bull sharks live to be 24.2 years and the oldest male was 21.3 years. Researchers also found a female bull shark off the eastern coast of South Africa that was 32 years. ( Castro, 1996; Cruz-Martinez, et al., 2004) Join the Shark Trust for an online session about the current state of shark conservation, the key facts and figures and how we can engage visitors in concrete action for sharks.As discussed above, bull sharks do frequent many of the same areas that humans do. Because of this, they are responsible for large numbers of shark bites. They hunt in murky water, so it is difficult to see them approaching. Despite this, it is incredibly unlikely you will be the victim of a shark bite. In fact, you are more likely to have a vending machine fall on you!
