Do sharks speak? If they did, they would be crying out for help. In general, sharks do not vocalize and are silent and stealthy hunters. However, our local swell shark (Cephaloscyllium ventriosum) can gulp air and bark to deter predatiors!
These Cat sharks live from the shallows to 500 meters deep and also glow, or biofluoresce as a form of intra-species communication. How cool is that?

Give sharks a voice. Join us in San Francisco at a multimedia event with our ocean images and colleagues Michael Stocker of Ocean Science Research combatting ocean noise pollution. Meditate with sound healer Joshua Miller for an evening of ocean sounds, images and healing solutions.*
At the rate that sharks are being finned and overfished, the cry of sharks is fading. It is up to us to shout out for sharks. Now the effectiveness of your tax deductible donations will be doubled by a private donor, saving thousands more sharks from the shark fin trade, reaching more Asian consumers in Singapore and China and protecting more habitat for sharks and healthy ecosystems.
