A 2021 study helped illustrate this phenomenon by demonstrating that migratory bonnethead sharks change their swimming patterns when exposed to different magnetic fields.
Here’s what that looks like in a small pool:
It sounds counterintuitive, but the sharks that live at the depths of the ocean have to swim against their body’s natural inclination to float to the surface.
A study on baby epaulette sharks found they are often born weak and undernourished. Only time will tell what effect climate change will have — and how long some species will be able to survive in the wild.
