Submarines have been using low and mid-frequency active sonar technology, a deafening soundwave that is dangerous even 300 miles from it's source. Some mid-frequency sonar systems can put out over 235 decibals, which is about as loud as a rocket launch.
Animals for hundreds of miles literally jump out of the ocean to try to avoid the sound. The damaging effects vary, bet are akin to decompression sickness causing internal bleeding and bursting organs including lungs and eardrums. When beached dolphins are reported this sonar technology is rarely mentioned in the news, although the link has been demonstrated.
If you've had an organ transplant, it is best to avoid eating grapefruit or drinking grapefruit juice (it interferes with the anti-rejection drugs in your blood).

Sharks have special organs called ampullae of Lorenzini that detect the tiny electric fields produced by other animals' muscles, which helps them find hidden prey.
Snakes flick their tongues to collect scent particles from the air and deliver them to the Jacobson's organ in the roof of the mouth, which basically lets them smell with their tongues.
