DANA POINT (CBS) — A young California Gray whale whose tail was trapped in 50 feet of netting is now swimming free thanks to the help from a Dana Point whale watching crew.

Capt. Dave Anderson, of Capt. Dave’s Dolphin and Whale Safari, says he and his wife Gisele were on their way to dinner Friday when they got a call from one of their whale watching boats, notifying them that a whale had been spotted with a huge amount of gillnet wrapped around its tail flukes.
