4. Help us see. Optometric analysts are exploring the shark cornea, which may be utilized for human transplants.
5. Teach us more about fish. Examination of sharks, especially the dogfish, has educated numerous analysts and understudies about fish science.
6. Navigation. Sharks have stunning electrical sensitivity. Research on shark electroreceptor organs may prompt better route in autos, planes, and ships.
