How many teeth does a shark need?

Shark teeth are not anchored in the jawbone like human teeth; they are attached to the skin by soft tissue. As a result and as seen here, they can easily break off when they attack their prey. But that doesn’t bother a shark – it has several hundred teeth in its mouth and they grow back over and over again. Scientists estimate that shark teeth take between eight and 15 days to grow, bringing the grand total of teeth Jaws may need in his lifetime close to 30,000.
