IUCN Red List Status: Near Threatened
Uniquely identified as a species of shark that can exist in freshwater for long periods of time, the bull shark can be found in tropical and subtropical habitats
The bull shark has been found large distances (several thousand miles!) up freshwater rivers, such as the Amazon, Ganges, and Mississippi (as far north as Illinois!) Rivers
Rarely targeted within fisheries, although caught as bycatch
Because this species is often found in freshwater, this puts them at unique risk to be exploited by freshwater fishing and habitat modification
This species has numerous common names, depending on the location, and include names such as Zambezi Shark, Swan River Shark, and Lake Nicaragua Shark
Commonly reach sizes up to 8.5 feet, but reported up to 13 feet
This species is responsible for a number of attacks on humans
Bull sharks are also well adapted to be on display in aquariums
Typically found in waters less than 30meters, but up to 150meters
This species is viviparous, with pups being nourished through a placental connection to the mother, resulting in live birth after gestation, which is 10-11 months
