Bull sharks have occasionally gone as far upstream in the Mississippi River as Alton, Illinois. [32] Bull sharks have also been found in the Potomac River in St. Mary's County, Maryland.

Larger tiger sharks inhabit the upper region of the tank where their dorsal fin is breaking the surface frequently.

[99] Sharks are common down to depths of 2,000 metres (7,000 ft), and some live even deeper, but they are almost entirely absent below 3,000 metres (10,000 ft).
Bull sharks can grow up to 11 feet long and weigh up to 700 pounds. The species has been implicated in the third-most attacks on humans globally, trailing only Great White and Tiger sharks, ...
There are living Greenland sharks that were around at the same time as George Washington’s presidency in 1789. That’s because the life expectancy of a Greenland shark is over 500 years.
The Greenland shark had been estimated to live to about 200 years, but a study published in 2016 found that a 5.02 m (16.5 ft) specimen was between 272 and 512 years old. [75] [76] That makes the Greenland shark the longest-lived vertebrate. [77] The maximum lifespan of the freshwater pearl mussel (Margaritifera margaritifera) may be 210–250 ...
