This incredible animal evolved in such a way that its kidneys, liver and rectal gland can gradually adjust to the salinity of the water in which they are found. One of their main characteristics, which differentiates Bull Sharks from all other types of sharks, is their unusual ability to adapt their organs to freshwater. Young Bull Sharks can be recognized by their dark spots on their fins, which will disappear as they grow older.ħ. Bull Sharks get their name from their overall appearance: Broad flat snout, large stout body, darker coloration on the back, unpredictable.Ħ. In comparison, a male Rainbow Trout’s average sits at 300 ng/ml and a male human adult’s at 2.50 to 9.50 ng/ml.ĥ. With 358 ng/ml (nanograms per milliliter) one shark tested even higher than a male African Elephant in heat with 64.4 gn/ml.īut can one Bull Shark speak for them all? Are unfathomable high testosterone levels the reason for aggressive behavior? In reality, their blood contains levels almost a hundred times lower, between 2 to 10 ng/ml. Bull Sharks’ testosterone levels are believed to be the highest in the animal kingdom. This is about 60 times as heavy as a domestic cat.Ĥ. Bull Sharks can grow to a length of up to 11 ft/ 3.3 m and, depending on their age, weigh between 198 and 570 lbs/ 90 and 259 kg. An Olympic champion like Caeleb Dressel who recently broke Michael Phelps’ world record can reach up to 9 mph/ 14.6 kph. Humans on the other hand can swim at an average of 2 mph/ 3 kph. Bull Sharks are incredibly agile in the water, reaching speeds of up to 25 mph/ 40 kph. How about a human, do you wonder? Entire 62psi! Although the human record is held by Richard Hofmann from Florida, USA, who achieved a bite strength of 975 psi, which is that of a Grizzly Bear!Ģ. In comparison, a Nile Crocodile can bite at 5,000psi, a Great White Shark at 4,000psi, a Hippo at 1,800psi, a Jaguar at 1,500psi, a Gorilla at 1,300psi and a Polar Bear at 1,200psi. With up to 1,350psi (pounds per square inch) the average bite strength of Bull Sharks ranks among the top 10 of the most powerful bites among animals.
