DNA test results reveal the shark responsible for biting a 46-year-old man off the coast of Del Mar in June was a juvenile white shark, approximately nine feet long. Dr. Chris Lowe of the Shark Lab at Cal State Long Beach told CBS 8 they estimate the shark was approximately six to seven years old. He said the next step in testing would be to try and determine exactly which shark bit the man. "This technique has never been done before," he said. "But our goal is, because we have the white shark genome, it is fully sequenced much like a human genome, and we can identify many of the genes, we think it's possible to do a 23-and-me type analysis to identify the shark to species. We won't know until we try." MORE: https://www.cbs8.com/article/news/local/dna-results-reveal-juvenile-white-shark-bit-man-off-del-mar-coast/509-cdd1e8af-4c83-4ddf-83a0-b8a4164287f1
