Narrator: This is Science Today. Sharks are some of the fiercest and oldest predators on the planet, so they naturally elicit public fear and fascination. To increase the knowledge and awareness of sharks and rays, researchers at the University of California , San Diego 's Scripps Institution of Oceanography are launching a shark consortium – an idea conceived by research physiologist and marine biologist Jeffrey Graham.
Graham: A very important objective of this consortium will be to raise public awareness about the natural history and ecology of many of the sharks and rays that occur in the coastal waters of San Diego and Northern Baja, California . Certainly those populations are changing the past century. They've all declined partially due to fishing, partially however also due to the encroachment of human civilization into areas that are affecting the quality and the status of inland water bodies.Narrator: Graham says their main objective now is to tag sharks and rays with satellite or acoustic technology to gather data.
