How does the bull shark adapt to freshwater?
Their ability to tolerate freshwater is rooted in salt retention. Sharks must retain salt inside their bodies. Without it, their cells will rupture and cause bloating and death. Given this requirement, most sharks cannot enter fresh water, because their internal salt levels would become diluted.
How do fins help bull sharks survive?
Pectoral fins are located behind the bull shark’s head. It’s what they use to lift and steer themselves while they swim.

What are the structual adaptations of a shark?
Horizontal keel. The horizontal keel on the caudal peduncle of some sharks is an adaptation for fast swimming. It reduces turbulence.
