Just on a size basis, you'd think whales would have nothing to fear from crabs in the ocean. But the devices used to catch crabs for eating tend to come with ropes and other features that can entangle a whale just swimming by.
Scientists, regulators, and fishing fleets are aware, and taking steps to reduce the problem. Oregon Department of Fish and Wildlife has a hand in the solution; Dr. Caren Braby, ODFW Marine Resource Program Manager, pays a visit.
She's joined by Bob Eder, who catches crab for a living, and Dr. Leigh Torres at the Department of Fisheries and Wildlife at Oregon State University.
You can help track whales, our guests revealed, with a smartphone app called Whale mAPP.
