DNA test results are in on the shark that bit swimmer Caleb Adams last month in Del Mar, and they confirm it was a white shark. Scientists have also determined that it was about 6-7 years old, so still considered a juvenile. But what we don't know from those results is if it's still hanging out right off our coast. “They're probably one of the most mysterious and interesting animals on the planet,” said Dr. Chris Lowe, Director of the Shark Lab at Cal State Long Beach. He says they tested DNA from Caleb's wetsuit. “The DNA came back as positive for white shark and that's not surprising based on the magnitude of the bite and based on the bite marks we estimate that shark was approximately 9 feet long.” MORE: https://www.cbs8.com/article/news/local/swimmer-bit-by-shark-in-del-mar-recovering-injuries/509-cf0f657e-0a2c-4b66-b7ee-8751927246a5
