Entangled Whale, set free.

A few years ago there was a entanglement of a female humpback, after she had been cut free by her rescuers, she swum round and "muzzled " her volunteer rescuers, as if to acknowledge her thanks for their assistance.

I wonder if this one did the same.

I guess that heavy clicking we hear is the sonar whales use to navigate and "see" their world. Amazing footage !
