A fifty-ton female humpback whale swam into a web of crab lines off the coast of California, trapping her in a tangled mess. Hundreds of feet of line and hundreds of pounds of traps wrapped around her body as she struggled to stay afloat. Four divers came to her rescue, swimming under her belly. For an hour, they cut rope—dangerous work since one flap of her tail could have killed them. After they freed her, rather than immediately escaping, she swam to and gently nudged each diver. “It felt to me like she was thanking us,” one rescuer said.
